Package org.apache.groovy.parser.antlr4

# Class AbstractLexer

java.lang.Object
org.antlr.v4.runtime.Recognizer<java.lang.Integer,​org.antlr.v4.runtime.atn.LexerATNSimulator>
org.antlr.v4.runtime.Lexer
org.apache.groovy.parser.antlr4.AbstractLexer

All Implemented Interfaces:
  `org.antlr.v4.runtime.TokenSource`, `SyntaxErrorReportable`

Direct Known Subclasses:
  `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.
