Class AbstractInternalAntlrParser

java.lang.Object
  org.antlr.runtime.BaseRecognizer
      org.antlr.runtime.Parser
          org.eclipse.xtext.parser.antlr.AbstractInternalAntlrParser

public abstract class AbstractInternalAntlrParser
extends org.antlr.runtime.Parser

Base class for Xtext's generated parsers. It is reasonable customizable by means of object composition, e.g. error messages can be tailored to specific needs with an ISyntaxErrorMessageProvider, objects construction is subject to an IAstFactory.
