Class ParserExtension

  • public abstract class ParserExtension
    extends Object
    This class represents an extension base class to the Lucene standard QueryParser. The QueryParser is generated by the JavaCC parser generator. Changing or adding functionality or syntax in the standard query parser requires changes to the JavaCC source file. To enable extending the standard query parser without changing the JavaCC sources and re-generate the parser the ParserExtension can be customized and plugged into an instance of ExtendableQueryParser, a direct subclass of QueryParser.
