Class AbstractParser

java.lang.Object

org.antlr.v4.runtime.Recognizer<org.antlr.v4.runtime.Token,org.antlr.v4.runtime.atn.ParserATNSimulator>

org.antlr.v4.runtime.Parser

org.apache.groovy.parser.antlr4.AbstractParser

All Implemented Interfaces:

SyntaxErrorReportable

Direct Known Subclasses:

GroovyParser

public abstract class AbstractParser
extends org.antlr.v4.runtime.Parser
implements SyntaxErrorReportable

Because antlr4 does not support generating parser with specified interface, we have to create a super class for it and implement the interface.
