Package org.apache.groovy.parser.antlr4

Class AbstractLexer

java.lang.Object
org.antlr.v4.runtime.Recognizer<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.
