C# Class Antlr4.Runtime.Atn.LexerIndexedCustomAction

This implementation of ILexerAction is used for tracking input offsets for position-dependent actions within a LexerActionExecutor .

This action is not serialized as part of the ATN, and is only required for position-dependent lexer actions which appear at a location other than the end of a rule. For more information about DFA optimizations employed for lexer actions, see LexerActionExecutor.Append(LexerActionExecutor, ILexerAction) and LexerActionExecutor.FixOffsetBeforeMatch(int) .

Méthode Description
Equals ( object obj ) : bool
Execute ( Lexer lexer ) : void

This method calls Execute(Antlr4.Runtime.Lexer) on the result of Action() using the provided lexer .
GetHashCode ( ) : int
LexerIndexedCustomAction ( int offset, ILexerAction action ) : Antlr4.Runtime

Constructs a new indexed custom action by associating a character offset with a ILexerAction .

Note: This class is only required for lexer actions for which ILexerAction.IsPositionDependent() returns .
