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.
