+This is a grammar for Cayenen internal parser for templates rendering
+
+Supported features:
+
+- #if(condition) #else #end conditions
+- variable evaluation: $a replaced to String return by a.toString() call or by empty string if a is null
+- method evaluation: $a.m($arg, '', 123) (can be used as #if condition)
+- custom directives via #directive syntax
+- line comments from ## to end of line
+
+This template will be resolved correctly
+    SELECT #result('A' 'a')
+    FROM $table
+    WHERE
+        #if($a)
+        COLUMN1 #bindNotEqual($helper.cayenneExp($a, 'db:ID_COLUMN1'))
+        AND
+        COLUMN2 #bindNotEqual($helper.cayenneExp($a, 'db:ID_COLUMN2'))
+        #else
+        COLUMN3 IS NULL
+        #end
+
+
+
+Comparision to Velocity:
+- no escape syntax, i.e. ${a}, directives and vars must be space separated
+- no arrays syntax
+- no #set directive
+- no loops
+- no complex expressions (neither logical nor math)
+- no evaluation of string literals, i.e. "$a/$b" will be untouched
+- no include / parse of external resources
+- no different comment styles
+- no macro
+- no other advanced features..

-/**
- * A custom Velocity directive to create a PreparedStatement parameter text.
- * There are the following possible invocation formats inside the template:
- * 
- * <pre>
- * #bind(value) - e.g. #bind($xyz)
- * #bind(value jdbc_type_name) - e.g. #bind($xyz 'VARCHAR'). This is the most common and useful form.
- * #bind(value jdbc_type_name, scale) - e.g. #bind($xyz 'VARCHAR' 2)
- * </pre>
- * <p>
- * Other examples:
- * </p>
- * <p>
- * <strong>Binding literal parameter value:</strong>
- * </p>
- * <p>
- * <code>"WHERE SOME_COLUMN &gt; #bind($xyz)"</code> produces
- * <code>"WHERE SOME_COLUMN &gt; ?"</code> and also places the value of the
- * "xyz" parameter in the context "bindings" collection.
- * </p>
- * <p>
- * <strong>Binding ID column of a DataObject value:</strong>
- * </p>
- * <p>
- * <code>"WHERE ID_COL1 = #bind($helper.cayenneExp($xyz, 'db:ID_COL2')) 
- * AND ID_COL2 = #bind($helper.cayenneExp($xyz, 'db:ID_COL2'))"</code> produces
- * <code>"WHERE ID_COL1 = ? AND ID_COL2 = ?"</code> and also places the values
- * of id columns of the DataObject parameter "xyz" in the context "bindings"
- * collection.

- * 
- * <pre>
- *       #result(column_name) - e.g. #result('ARTIST_ID')
- *       #result(column_name java_type) - e.g. #result('ARTIST_ID' 'String')

- *       #result(column_name java_type column_alias data_row_key) - e.g. #result('ARTIST_ID' 'String' 'ID' 'toArtist.ID')
- * </pre>
- * 
- * <p>
- * 'data_row_key' is needed if SQL 'column_alias' is not appropriate as a
- * DataRow key on the Cayenne side. One common case when this happens is when a
- * DataRow retrieved from a query is mapped using joint prefetch keys. In this
- * case DataRow must use DB_PATH expressions for joint column keys, and their
- * format is incompatible with most databases alias format.
- * </p>
- * <p>
- * Most common Java types used in JDBC can be specified without a package. This
- * includes all numeric types, primitives, String, SQL dates, BigDecimal and
- * BigInteger.

+ * <p>
+ * <strong>Binding literal parameter value:</strong>
+ * </p>
+ * <p>
+ * <code>"WHERE SOME_COLUMN &gt; #bind($xyz)"</code> produces

+ * <code>"WHERE ID_COL1 = #bind($helper.cayenneExp($xyz, 'db:ID_COL2')) 
+ * AND ID_COL2 = #bind($helper.cayenneExp($xyz, 'db:ID_COL2'))"</code> produces
