Class AbstractLexer

  • All Implemented Interfaces:
    org.antlr.v4.runtime.TokenSource, SyntaxErrorReportable
    Direct Known Subclasses:
    org.apache.groovy.parser.antlr4.GroovyLexer

    public abstract class AbstractLexer
    extends org.antlr.v4.runtime.Lexer
    implements SyntaxErrorReportable
    Because antlr4 does not support generating lexer with specified interface, we have to create a super class for it and implement the interface.
