Class JavaScriptLexerBase

  • All Implemented Interfaces:
    org.antlr.v4.runtime.TokenSource
    Direct Known Subclasses:
    JavaScriptLexer
    public abstract class JavaScriptLexerBase
extends org.antlr.v4.runtime.Lexer
    All lexer methods that used in grammar (IsStrictMode) should start with Upper Case Char similar to Lexer rules.

        public org.antlr.v4.runtime.Token nextToken()
        Return the next token from the character stream and records this last token in case it resides on the default channel. This recorded token is used to determine when the lexer could possibly match a regex literal. Also changes scopeStrictModes stack if tokenize special string 'use strict';
        Specified by:

        Returns:
        the next token from the character stream.
