-/**
- * A Bloom filter: a lossy data structure for set representation. A Bloom filter consists of a bit
- * set and a set of hash functions. A Bloom filter has two operations: add and query. We can add an
- * object to a Bloom filter to indicate that it should be considered part of the set that the Bloom
- * filter represents. We can query the Bloom filter to see if a given object is considered part of
- * its set.
- * <p>
- * An object is added by sending it through a number of hash functions, each of which returns an
- * index into the bit set. The bit at each of the indices is flipped on. We can query for an abject
- * by sending it through the same hash functions. Then we look the bit at each index that was
- * returned by a hash function. If any of the bits is unset, we know that the object is not in the
- * Bloom filter (for otherwise all the bits should have already been set). If all the bits are set,
- * we assume that the object is present in the Bloom filter.
- * <p>
- * We cannot know for sure that an object is in the bloom filter just because all its bits were set.
- * There may be many collisions in the hash space, and all the bits for some object might be set by
- * chance, rather than by adding that particular object.
- * <p>
- * The advantage of a Bloom filter is that its set representation can be stored in a significantly
- * smaller space than information-theoretic lossless lower bounds. The price we pay for this is a
- * certain amount of error in the query function. One nice feature of the Bloom filter is that its
- * error is one-sided. This means that while the query function may return false positives (saying
- * an object is present when it really isn't), it can never return false negatives (saying that an
- * object is not present when it was already added.

-Provides abstraction and support for the language model feature function typically used in
-hierarchical phrase-based decoding for statistical machine translation.
-
-The classes contained within this directory are responsible for two tasks: implementing the feature
-function, and representing the language model itself. The class `LanguageModelFF` implements the
-feature function by exending the class `DefaultStatefulFF`. One of these is instantiated for each
-language model present in the decoder.
-
-The language models themselves are implemented as a combination of an interface
-(`NGramLanguageModel`), a default implementation (`DefaultNgramLangaugeModel`), and an abstract
-implementation of the default (`AbstractLM`).
-
-<pre>
- DefaultStatefulFF
- |- LanguageModelFF
-
- DefaultNgramLanguageModel implements interface NGramLanguageModel

-
-Provides an implementation of the linear feature functions typically used in
-hierarchical phrase-based decoding for statistical machine translation.
-
-The following is a note from Juri describing some of the functionality of the feature functions
-interfaces and default abstract classes.
-
-<pre>
-The equality that I intended for is ff.transitionLogP() =
-ff.estimateLogP() + ff.reEstimateTransitionLogP(). The re-estimate
-fixes the estimate to be the true transition cost that takes into
-account the state. Before decoding the cost of applying a rule is
-estimated via estimateLogP() and yields the phrasal feature costs plus
-an LM estimate of the cost of the lexical portions of the rule.
-transitionLogP() takes rule and state and computes everything from
-scratch, whereas reEstimateTransitionLogP() adds in the cost of new
-n-grams that result from combining the rule with the LM states and
-subtracts out the cost of superfluous less-than-n-grams that were
-overridden by the updated cost calculation.
-
-Hope this helps.

-/**
- * This class implements lazy k-best extraction on a hyper-graph.
- *
- * K-best extraction over hypergraphs is a little hairy, but is best understood in the following
- * manner. Imagine a hypergraph, which is composed of nodes connected by hyperedges. A hyperedge has
- * exactly one parent node and 1 or more tail nodes, corresponding to the rank of the rule that gave
- * rise to the hyperedge. Each node has 1 or more incoming hyperedges.
- *
- * K-best extraction works in the following manner. A derivation is a set of nodes and hyperedges
- * that leads from the root node down and exactly covers the source-side sentence. To define a
- * derivation, we start at the root node, choose one of its incoming hyperedges, and then recurse to
- * the tail (or antecedent) nodes of that hyperedge, where we continually make the same decision.
- *
- * Each hypernode has its hyperedges sorted according to their model score. To get the best
- * (Viterbi) derivation, we simply recursively follow the best hyperedge coming in to each
- * hypernode.
- *
- * How do we get the second-best derivation? It is defined by changing exactly one of the decisions
- * about which hyperedge to follow in the recursion. Somewhere, we take the second-best. Similarly,
- * the third-best derivation makes a single change from the second-best: either making another
- * (differnt) second-best choice somewhere along the 1-best derivation, or taking the third-best
- * choice at the same spot where the second-best derivation took the second-best choice. And so on.
- *
- * This class uses two classes that encode the necessary meta-information. The first is the
- * DerivationState class. It roughly corresponds to a hyperedge, and records, for each of that
- * hyperedge's tail nodes, which-best to take. So for a hyperedge with three tail nodes, the 1-best
- * derivation will be (1,1,1), the second-best will be one of (2,1,1), (1,2,1), or (1,1,2), the
- * third best will be one of
- *
- * (3,1,1), (2,2,1), (1,1,3)
- *
- * and so on.
- *
- * The configuration parameter `output-format` controls what exactly is extracted from the forest.
- * See documentation for that below. Note that Joshua does not store individual feature values while
- * decoding, but only the cost of each edge (in the form of a float). Therefore, if you request
- * the features values (`%f` in `output-format`), the feature functions must be replayed, which
- * is expensive.
- *
- * The configuration parameter `top-n` controls how many items are returned. If this is set to 0,
- * k-best extraction should be turned off entirely.

-/**
- * This class handles decoder initialization and the complication introduced by multithreading.
- *
- * After initialization, the main entry point to the Decoder object is
- * decodeAll(TranslationRequest), which returns a set of Translation objects wrapped in an iterable
- * Translations object. It is important that we support multithreading both (a) across the sentences
- * within a request and (b) across requests, in a round-robin fashion. This is done by maintaining a
- * fixed sized concurrent thread pool. When a new request comes in, a RequestParallelizer thread is
- * launched. This object iterates over the request's sentences, obtaining a thread from the
- * thread pool, and using that thread to decode the sentence. If a decoding thread is not available,
- * it will block until one is in a fair (FIFO) manner. RequestParallelizer thereby permits intra-request
- * parallelization by separating out reading the input stream from processing the translated sentences,
- * but also ensures that round-robin parallelization occurs, since RequestParallelizer uses the
- * thread pool before translating each request.
- *
- * A decoding thread is handled by DecoderThread and launched from DecoderThreadRunner. The purpose
- * of the runner is to record where to place the translated sentence when it is done (i.e., which
- * Translations object). Translations itself is an iterator whose next() call blocks until the next
- * translation is available.

-package joshua.decoder.ff.tm.packed;
-
-/***
- * This package implements Joshua's packed grammar structure, which enables the efficient loading
- * and accessing of grammars. It is described in the paper:
- *
- * @article{ganitkevitch2012joshua,
- * Author = {Ganitkevitch, J. and Cao, Y. and Weese, J. and Post, M. and Callison-Burch, C.},
- * Journal = {Proceedings of WMT12},
- * Title = {Joshua 4.0: Packing, PRO, and paraphrases},
- * Year = {2012}}
- *
- * The packed grammar works by compiling out the grammar tries into a compact format that is loaded
- * and parsed directly from Java arrays. A fundamental problem is that Java arrays are indexed
- * by ints and not longs, meaning the maximum size of the packed grammar is about 2 GB. This forces
- * the use of packed grammar slices, which together constitute the grammar. The figure in the
- * paper above shows what each slice looks like.
- *
- * The division across slices is done in a depth-first manner. Consider the entire grammar organized
- * into a single source-side trie. The splits across tries are done by grouping the root-level
- * outgoing trie arcs --- and the entire trie beneath them --- across slices.
- *
- * This presents a problem: if the subtree rooted beneath a single top-level arc is too big for a
- * slice, the grammar can't be packed. This happens with very large Hiero grammars, for example,
- * where there are a *lot* of rules that start with [X].
- *
- * A solution being worked on is to split that symbol and pack them into separate grammars with a
- * shared vocabulary, and then rely on Joshua's ability to query multiple grammars for rules to
- * solve this problem. This is not currently implemented but could be done directly in the
- * Grammar Packer.
- *
- * *UPDATE 10/2015*
- * The introduction of a SliceAggregatingTrie together with sorting the grammar by the full source string
- * (not just by the first source word) allows distributing rules with the same first source word
- * across multiple slices.
- * @author fhieber

-/**
- * SliceAggregatingTrie collapses multiple tries
- * with the same source root (i.e. tries from multiple packed slices).
- *
- * Consider the example below.
- * Without SliceAggregatingTries, the following grammar rules could have only
- * partitioned by splitting rule lists when the first word of SOURCE changes. (">" markers).
- *
- * Using a SliceAggregatingTrie allows splitting at changes of second SOURCE words (">>" marker).
- *
- * EXAMPLE: (LHS ||| SOURCE ||| TARGET)
- * [X] ||| - ||| -
- * >
- * [X] ||| [X] ||| [X]
- * >>
- * [X] ||| [X] a ||| [X] A
- * [X] ||| [X] a ||| [X] A
- * >>
- * [X] ||| [X] b ||| [X] B
- * >
- * [X] ||| u ||| u
- *
- * A SliceAggregatingTrie node behaves just like a regular Trie node but subsumes a list of extensions/children.
- * This class hides the complexity of having multiple tries with the same root
- * from nodes one level up.
- * Similar to PackedRoot, it maintains a lookup table of children's
- * source-side words to know
- * in which subtrie (i.e. packedSlice) it needs to traverse into when
- * match() is called.
- * A SliceAggregatingTrie never holds any rules associated with it, thus
- * rules with the source-side represented by the SliceAggregatingTrie node
- * must be found in exactly one of the subtries.
- * (!) This assumption relies on the sort order of the packed grammar.
- * If the grammar was incorrectly sorted and then packed, construction
- * of SliceAggregatingTrie nodes fails.

-/**
- * This class defines Joshua's feature function interface, for both sparse and
- * dense features. It is immediately inherited by StatelessFF and StatefulFF,
- * which provide functionality common to stateless and stateful features,
- * respectively. Any feature implementation should extend those classes, and not
- * this one. The distinction between stateless and stateful features is somewhat
- * narrow: all features have the opportunity to return an instance of a
- * {@link DPState} object, and stateless ones just return null.
- *
- * Features in Joshua work like templates. Each feature function defines any
- * number of actual features, which are associated with weights. The task of the
- * feature function is to compute the features that are fired in different
- * circumstances and then return the inner product of those features with the
- * weight vector. Feature functions can also produce estimates of their future
- * cost (via {@link estimateCost()}); these values are not used in computing the
- * score, but are only used for sorting rules during cube pruning. The
- * individual features produced by each template should have globally unique
- * names; a good convention is to prefix each feature with the name of the
- * template that produced it.
- *
- * Joshua does not retain individual feature values while decoding, since this
- * requires keeping a sparse feature vector along every hyperedge, which can be
- * expensive. Instead, it computes only the weighted cost of each edge. If the
- * individual feature values are requested, the feature functions are replayed
- * in post-processing, say during k-best list extraction. This is implemented in
- * a generic way by passing an {@link Accumulator} object to the compute()
- * function. During decoding, the accumulator simply sums weighted features in a
- * scalar. During k-best extraction, when individual feature values are needed,
- * a {@link FeatureAccumulator} is used to retain the individual values.

- * An implementation of a sparse feature vector, using for representing both weights and feature
- * values.
- *
- * This class is used to hold both the decoder weights and the feature values accumulated across
- * each edge. When features are read in upon decoder startup, they all start out as sparse features
- * and are stored in the hash table. After the feature functions have been loaded, the decoder
- * queries each of them for their sparse features via {@link registerDenseFeatures}. Those features
- * returned by each decoder are then *removed* from the sparse feature hash and placed in the dense
- * feature array. Therefore, when a feature registers a dense feature, it should take care to
- * query either {@link getDense()} or {@link getSparse} when asking for the feature values later on.

+/**
+ * This class handles decoder initialization and the complication introduced by multithreading.
+ *
+ * After initialization, the main entry point to the Decoder object is
+ * decodeAll(TranslationRequest), which returns a set of Translation objects wrapped in an iterable
+ * Translations object. It is important that we support multithreading both (a) across the sentences
+ * within a request and (b) across requests, in a round-robin fashion. This is done by maintaining a
+ * fixed sized concurrent thread pool. When a new request comes in, a RequestParallelizer thread is
+ * launched. This object iterates over the request's sentences, obtaining a thread from the
+ * thread pool, and using that thread to decode the sentence. If a decoding thread is not available,
+ * it will block until one is in a fair (FIFO) manner. RequestParallelizer thereby permits intra-request
+ * parallelization by separating out reading the input stream from processing the translated sentences,
+ * but also ensures that round-robin parallelization occurs, since RequestParallelizer uses the
+ * thread pool before translating each request.
+ *
+ * A decoding thread is handled by DecoderThread and launched from DecoderThreadRunner. The purpose
+ * of the runner is to record where to place the translated sentence when it is done (i.e., which
+ * Translations object). Translations itself is an iterator whose next() call blocks until the next
+ * translation is available.

+package joshua.decoder.ff.tm.packed;
+
+/***
+ * This package implements Joshua's packed grammar structure, which enables the efficient loading
+ * and accessing of grammars. It is described in the paper:
+ *
+ * @article{ganitkevitch2012joshua,
+ * Author = {Ganitkevitch, J. and Cao, Y. and Weese, J. and Post, M. and Callison-Burch, C.},
+ * Journal = {Proceedings of WMT12},
+ * Title = {Joshua 4.0: Packing, PRO, and paraphrases},
+ * Year = {2012}}
+ *
+ * The packed grammar works by compiling out the grammar tries into a compact format that is loaded
+ * and parsed directly from Java arrays. A fundamental problem is that Java arrays are indexed
+ * by ints and not longs, meaning the maximum size of the packed grammar is about 2 GB. This forces
+ * the use of packed grammar slices, which together constitute the grammar. The figure in the
+ * paper above shows what each slice looks like.
+ *
+ * The division across slices is done in a depth-first manner. Consider the entire grammar organized
+ * into a single source-side trie. The splits across tries are done by grouping the root-level
+ * outgoing trie arcs --- and the entire trie beneath them --- across slices.
+ *
+ * This presents a problem: if the subtree rooted beneath a single top-level arc is too big for a
+ * slice, the grammar can't be packed. This happens with very large Hiero grammars, for example,
+ * where there are a *lot* of rules that start with [X].
+ *
+ * A solution being worked on is to split that symbol and pack them into separate grammars with a
+ * shared vocabulary, and then rely on Joshua's ability to query multiple grammars for rules to
+ * solve this problem. This is not currently implemented but could be done directly in the
+ * Grammar Packer.
+ *
+ * *UPDATE 10/2015*
+ * The introduction of a SliceAggregatingTrie together with sorting the grammar by the full source string
+ * (not just by the first source word) allows distributing rules with the same first source word
+ * across multiple slices.

+ * Consider the example below.
+ * Without SliceAggregatingTries, the following grammar rules could have only
+ * partitioned by splitting rule lists when the first word of SOURCE changes. (">" markers).
+ *
+ * Using a SliceAggregatingTrie allows splitting at changes of second SOURCE words (">>" marker).
+ *
+ * EXAMPLE: (LHS ||| SOURCE ||| TARGET)
+ * [X] ||| - ||| -
+ * >
+ * [X] ||| [X] ||| [X]
+ * >>
+ * [X] ||| [X] a ||| [X] A

+ * >
+ * [X] ||| u ||| u
+ *
+ * A SliceAggregatingTrie node behaves just like a regular Trie node but subsumes a list of extensions/children.
+ * This class hides the complexity of having multiple tries with the same root
+ * from nodes one level up.
+ * Similar to PackedRoot, it maintains a lookup table of children's
+ * source-side words to know
+ * in which subtrie (i.e. packedSlice) it needs to traverse into when
+ * match() is called.
+ * A SliceAggregatingTrie never holds any rules associated with it, thus
+ * rules with the source-side represented by the SliceAggregatingTrie node
+ * must be found in exactly one of the subtries.
+ * (!) This assumption relies on the sort order of the packed grammar.
+ * If the grammar was incorrectly sorted and then packed, construction

+/**
+ * This class implements lazy k-best extraction on a hyper-graph.
+ *
+ * K-best extraction over hypergraphs is a little hairy, but is best understood in the following
+ * manner. Imagine a hypergraph, which is composed of nodes connected by hyperedges. A hyperedge has
+ * exactly one parent node and 1 or more tail nodes, corresponding to the rank of the rule that gave
+ * rise to the hyperedge. Each node has 1 or more incoming hyperedges.
+ *
+ * K-best extraction works in the following manner. A derivation is a set of nodes and hyperedges
+ * that leads from the root node down and exactly covers the source-side sentence. To define a
+ * derivation, we start at the root node, choose one of its incoming hyperedges, and then recurse to
+ * the tail (or antecedent) nodes of that hyperedge, where we continually make the same decision.
+ *
+ * Each hypernode has its hyperedges sorted according to their model score. To get the best
+ * (Viterbi) derivation, we simply recursively follow the best hyperedge coming in to each
+ * hypernode.
+ *
+ * How do we get the second-best derivation? It is defined by changing exactly one of the decisions
+ * about which hyperedge to follow in the recursion. Somewhere, we take the second-best. Similarly,
+ * the third-best derivation makes a single change from the second-best: either making another
+ * (differnt) second-best choice somewhere along the 1-best derivation, or taking the third-best
+ * choice at the same spot where the second-best derivation took the second-best choice. And so on.
+ *
+ * This class uses two classes that encode the necessary meta-information. The first is the
+ * DerivationState class. It roughly corresponds to a hyperedge, and records, for each of that
+ * hyperedge's tail nodes, which-best to take. So for a hyperedge with three tail nodes, the 1-best
+ * derivation will be (1,1,1), the second-best will be one of (2,1,1), (1,2,1), or (1,1,2), the
+ * third best will be one of
+ *
+ * (3,1,1), (2,2,1), (1,1,3)
+ *
+ * and so on.
+ *
+ * The configuration parameter `output-format` controls what exactly is extracted from the forest.
+ * See documentation for that below. Note that Joshua does not store individual feature values while
+ * decoding, but only the cost of each edge (in the form of a float). Therefore, if you request
+ * the features values (`%f` in `output-format`), the feature functions must be replayed, which
+ * is expensive.
+ *
+ * The configuration parameter `top-n` controls how many items are returned. If this is set to 0,
+ * k-best extraction should be turned off entirely.

+/**
+ * A Bloom filter: a lossy data structure for set representation. A Bloom filter consists of a bit
+ * set and a set of hash functions. A Bloom filter has two operations: add and query. We can add an
+ * object to a Bloom filter to indicate that it should be considered part of the set that the Bloom
+ * filter represents. We can query the Bloom filter to see if a given object is considered part of
+ * its set.
+ * <p>
+ * An object is added by sending it through a number of hash functions, each of which returns an
+ * index into the bit set. The bit at each of the indices is flipped on. We can query for an abject
+ * by sending it through the same hash functions. Then we look the bit at each index that was
+ * returned by a hash function. If any of the bits is unset, we know that the object is not in the
+ * Bloom filter (for otherwise all the bits should have already been set). If all the bits are set,
+ * we assume that the object is present in the Bloom filter.
+ * <p>
+ * We cannot know for sure that an object is in the bloom filter just because all its bits were set.
+ * There may be many collisions in the hash space, and all the bits for some object might be set by
+ * chance, rather than by adding that particular object.

+
+Provides abstraction and support for the language model feature function typically used in
+hierarchical phrase-based decoding for statistical machine translation.
+
+The classes contained within this directory are responsible for two tasks: implementing the feature
+function, and representing the language model itself. The class `LanguageModelFF` implements the
+feature function by exending the class `DefaultStatefulFF`. One of these is instantiated for each
+language model present in the decoder.
+
+The language models themselves are implemented as a combination of an interface
+(`NGramLanguageModel`), a default implementation (`DefaultNgramLangaugeModel`), and an abstract
+implementation of the default (`AbstractLM`).
+
+<pre>
+ DefaultStatefulFF
+ |- LanguageModelFF
+
+ DefaultNgramLanguageModel implements interface NGramLanguageModel
+ |- AbstractLM

+Provides an implementation of the linear feature functions typically used in
+hierarchical phrase-based decoding for statistical machine translation.
+
+The following is a note from Juri describing some of the functionality of the feature functions
+interfaces and default abstract classes.
+
+<pre>
+The equality that I intended for is ff.transitionLogP() =
+ff.estimateLogP() + ff.reEstimateTransitionLogP(). The re-estimate
+fixes the estimate to be the true transition cost that takes into
+account the state. Before decoding the cost of applying a rule is
+estimated via estimateLogP() and yields the phrasal feature costs plus
+an LM estimate of the cost of the lexical portions of the rule.
+transitionLogP() takes rule and state and computes everything from
+scratch, whereas reEstimateTransitionLogP() adds in the cost of new
+n-grams that result from combining the rule with the LM states and
+subtracts out the cost of superfluous less-than-n-grams that were
+overridden by the updated cost calculation.
+
+Hope this helps.

+ * For a word match, simply follow that arc along the trie. We create a parallel arc in our
+ * filtered grammar to represent it. Each arc in the filtered trie knows about its
+ * corresponding/underlying node in the unfiltered grammar trie.
+ *
+ * A nonterminal is always permitted to match. The question then is how much of the input sentence
+ * we imagine it consumed. The answer is that it could have been any amount. So the recursive call
+ * has to be a set of calls, one each to the next trie node with different lengths of the sentence
+ * remaining.
+ *
+ * A problem occurs when we have multiple sequential nonterminals. For scope-3 grammars, there can
+ * be four sequential nonterminals (in the case when they are grounded by terminals on both ends
+ * of the nonterminal chain). We'd like to avoid looking at all possible ways to split up the
+ * subsequence, because with respect to filtering rules, they are all the same.
+ *
+ * We accomplish this with the following restriction: for purposes of grammar filtering, only the
+ * first in a sequence of nonterminal traversals can consume more than one word. Each of the
+ * subsequent ones would have to consume just one word. We then just have to record in the

+/**
+ * This class defines Joshua's feature function interface, for both sparse and
+ * dense features. It is immediately inherited by StatelessFF and StatefulFF,
+ * which provide functionality common to stateless and stateful features,
+ * respectively. Any feature implementation should extend those classes, and not
+ * this one. The distinction between stateless and stateful features is somewhat
+ * narrow: all features have the opportunity to return an instance of a
+ * {@link DPState} object, and stateless ones just return null.
+ *
+ * Features in Joshua work like templates. Each feature function defines any
+ * number of actual features, which are associated with weights. The task of the
+ * feature function is to compute the features that are fired in different
+ * circumstances and then return the inner product of those features with the
+ * weight vector. Feature functions can also produce estimates of their future
+ * cost (via {@link estimateCost()}); these values are not used in computing the
+ * score, but are only used for sorting rules during cube pruning. The
+ * individual features produced by each template should have globally unique
+ * names; a good convention is to prefix each feature with the name of the
+ * template that produced it.
+ *
+ * Joshua does not retain individual feature values while decoding, since this
+ * requires keeping a sparse feature vector along every hyperedge, which can be
+ * expensive. Instead, it computes only the weighted cost of each edge. If the
+ * individual feature values are requested, the feature functions are replayed
+ * in post-processing, say during k-best list extraction. This is implemented in
+ * a generic way by passing an {@link Accumulator} object to the compute()
+ * function. During decoding, the accumulator simply sums weighted features in a
+ * scalar. During k-best extraction, when individual feature values are needed,
+ * a {@link FeatureAccumulator} is used to retain the individual values.

- * CKY-based decoding makes extensive use of charts, which maintain information about spans (i, j)

-/**
- * Feature function that reads in a list of language model fragments and matches them against the
- * hypergraph. This allows for language model fragment "glue" features, which fire when LM fragments
- * (supplied as input) are assembled. These LM fragments are presumably useful in ensuring
- * grammaticality and can be independent of the translation model fragments.
- *
- * Usage: in the Joshua Configuration file, put
- *
- * feature-function = FragmentLM -lm LM_FRAGMENTS_FILE -map RULE_FRAGMENTS_MAP_FILE
- *
- * LM_FRAGMENTS_FILE is a pointer to a file containing a list of fragments that it should look for.
- * The format of the file is one fragment per line in PTB format, e.g.:
- *
- * (S NP (VP (VBD said) SBAR) (. .))
- *
- * RULE_FRAGMENTS_MAP_FILE points to a file that maps fragments to the flattened SCFG rule format
- * that Joshua uses. This mapping is necessary because Joshua's rules have been flattened, meaning
- * that their internal structure has been removed, yet this structure is needed for matching LM
- * fragments. The format of the file is
- *
- * FRAGMENT ||| RULE-TARGET-SIDE
- *
- * for example,
- *
- * (S (NP (DT the) (NN man)) VP .) ||| the man [VP,1] [.,2] (SBAR (IN that) (S (NP (PRP he)) (VP
- * (VBD was) (VB done)))) ||| that he was done (VP (VBD said) SBAR) ||| said SBAR
