+<div class="block">Makes implementing and using UDFs easier by enabling named parameters.
+
+ <p>
+ This works by capturing the schema of the input tuple on the front-end and storing it into the UDFContext.
+ It provides an easy means of referencing the parameters on the back-end to aid in writing schema-based UDFs.
+ </p>
+
+ <p>
+ A related class is <a href="../../../datafu/pig/util/SimpleEvalFunc.html" title="class in datafu.pig.util"><code>SimpleEvalFunc</code></a>. However they are actually fairly different. The primary purpose of <a href="../../../datafu/pig/util/SimpleEvalFunc.html" title="class in datafu.pig.util"><code>SimpleEvalFunc</code></a> is
+ to skip the boilerplate under the assumption that the arguments in and out are well... simple.
+ It also assumes that these arguments are in a well-defined positional ordering.
+ </p>
+
+ <p>
+ AliasableEvalFunc allows the UDF writer to avoid dealing with all positional assumptions and instead reference fields
+ by their aliases. This practice allows for more readable code since the alias names should have more meaning
+ to the reader than the position. This approach is also less error prone since it creates a more explicit contract
+ for what input the UDF expects and prevents simple mistakes that positional-based UDFs could not easily catch,
+ such as transposing two fields of the same type. If this contract is violated, say, by attempting to reference
+ a field that is not present, a meaningful error message may be thrown.
+ </p>
+
+ Example: This example computes the monthly payments for mortgages depending on interest rate.
+ <pre>
+ <code>public class MortgagePayment extends AliasableEvalFunc<DataBag> {
+ ...
+ public DataBag exec(Tuple input) throws IOException {
+ DataBag output = BagFactory.getInstance().newDefaultBag();
+
+ Double principal = getDouble(input, "principal"); // get a value from the input tuple by alias
+ Integer numPayments = getInteger(input, "num_payments");
+ DataBag interestRates = getBag(input, "interest_rates");
+
+ for (Tuple interestTuple : interestRates) {
+ Double interest = getDouble(interestTuple, getPrefixedAliasName("interest_rates", "interest_rate")); // get a value from the inner bag tuple by alias
+ double monthlyPayment = computeMonthlyPayment(principal, numPayments, interest);
+ output.add(TupleFactory.getInstance().newTuple(monthlyPayment));
+ }
+ return output;
+ }
+ }
+ </code>

+<div class="block">Filter function which asserts that a value is true.
+
+ <p>
+ Unfortunately, the Pig interpreter doesn't recognize boolean expressions nested as function
+ arguments, so this uses C-style booleans. That is, the first argument should be
+ an integer. 0 is interpreted as "false", and anything else is considered "true".
+ The function will cause the Pig script to fail if a "false" value is encountered.
+ </p>
+
+ <p>
+ There is a unary and a binary version. The unary version just takes a boolean, and throws out a generic exception message when the
+ assertion is violated. The binary version takes a String as a second argument and throws that out when the assertion
+ is violated.
+ </p>
+
+ Example:
+ <pre>
+ <code>FILTER members BY AssertUDF( (member_id >= 0 ? 1 : 0), 'Doh! Some member ID is negative.' );
