org.exist.xquery.parser
Class XQueryParser

java.lang.Object
  extended by antlr.Parser
      extended by antlr.LLkParser
          extended by org.exist.xquery.parser.XQueryParser
All Implemented Interfaces:
XQueryTokenTypes
public class XQueryParser
extends LLkParser
implements XQueryTokenTypes

eXist parses an XQuery expression in (currently) 4 phases: 1) lexical analysis in XQueryLexer 2) syntax analysis and construction of an intermediate AST (abstract syntax tree) in XQueryParser 3) analysis of the intermediate AST, and construction of the executable XQuery expression tree from the intermediate AST in XQueryTreeParser 4) static analysis of the final expression tree The grammar in XQuery.g corresponds to phase 2. It generates an intermediate AST which will then be parsed a second time by XQueryTree.g. ANTLR provides a special syntax for tree parsers. Every action returns an AST node and the # references these nodes. #[VARIABLE_BINDING, varName] constructs a new AST node of type VARIABLE_BINDING, which is prepended to the default AST generated by the production. ANTLR's meta language for tree construction is described in the ANTLR reference manual: http://www.antlr.org/doc/index.html .
