org.antlr.v4.runtime.Recognizer<java.lang.Integer,org.antlr.v4.runtime.atn.LexerATNSimulator>

org.antlr.v4.runtime.Lexer

io.doov.tsparser.JavaScriptBaseLexer

All Implemented Interfaces:

org.antlr.v4.runtime.TokenSource

Direct Known Subclasses:

JavaScriptLexer, TypeScriptLexer

public abstract class JavaScriptBaseLexer
extends org.antlr.v4.runtime.Lexer

All lexer methods that used in grammar (IsStrictMode) should start with Upper Case Char similar to Lexer rules.

Method Detail

getStrictDefault

public boolean getStrictDefault()

setUseStrictDefault

public void setUseStrictDefault(boolean value)

IsSrictMode

public boolean IsSrictMode()

nextToken

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:

nextToken in interface org.antlr.v4.runtime.TokenSource

Overrides:

nextToken in class org.antlr.v4.runtime.Lexer

Returns:

the next token from the character stream.

RegexPossible

protected boolean RegexPossible()

Returns true if the lexer can match a regex literal.

Returns:

regexPossible
