/** \file
 *  This C header file was generated by $ANTLR version 3.2 debian-5
 *
 *     -  From the grammar source file : DAAP2SQL.g
 *     -                            On : 2011-09-11 15:48:50
 *     -           for the tree parser : DAAP2SQLTreeParser *
 * Editing it, at least manually, is not wise. 
 *
 * C language generator and runtime by Jim Idle, jimi|hereisanat|idle|dotgoeshere|ws.
 *
 *
 * The tree parser DAAP2SQL has the callable functions (rules) shown below,
 * which will invoke the code for the associated rule in the source grammar
 * assuming that the input stream is pointing to a token/text stream that could begin
 * this rule.
 * 
 * For instance if you call the first (topmost) rule in a parser grammar, you will
 * get the results of a full parse, but calling a rule half way through the grammar will
 * allow you to pass part of a full token stream to the parser, such as for syntax checking
 * in editors and so on.
 *
 * The parser entry points are called indirectly (by function pointer to function) via
 * a parser context typedef pDAAP2SQL, which is returned from a call to DAAP2SQLNew().
 *
 * The methods in pDAAP2SQL are  as follows:
 *
 *  - pANTLR3_STRING      pDAAP2SQL->query(pDAAP2SQL)
 *  - DAAP2SQL_expr_return      pDAAP2SQL->expr(pDAAP2SQL)
 *
 * The return type for any particular rule is of course determined by the source
 * grammar file.
