Function NewGScriptLexer

parser/gscript_lexer.go:321–341

NewGScriptLexer produces a new lexer instance for the optional input antlr.CharStream. The *GScriptLexer instance produced may be reused by calling the SetInputStream method. The initial lexer configuration is expensive to construct, and the object is not thread-safe; however, if used within a Gola

(input antlr.CharStream)

// however, if used within a Golang sync.Pool, the construction cost amortizes well and the
// objects can be used in a thread-safe manner.
func NewGScriptLexer(input antlr.CharStream) *GScriptLexer {

	lexerDeserializer := antlr.NewATNDeserializer(nil)
	lexerAtn := lexerDeserializer.DeserializeFromUInt16(serializedLexerAtn)
	lexerDecisionToDFA := make([]*antlr.DFA, len(lexerAtn.DecisionToState))
	for index, ds := range lexerAtn.DecisionToState {
		lexerDecisionToDFA[index] = antlr.NewDFA(ds, index)
