Package org.eclipse.xtext.parser.antlr

Class AbstractInternalAntlrParser

  • Direct Known Subclasses:
    InternalXtextParser
    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.
