Execute() public method

Execute the actions encapsulated by this executor within the context of a particular Antlr4.Runtime.Lexer .

This method calls Antlr4.Runtime.IIntStream.Seek(int) to set the position of the input Antlr4.Runtime.ICharStream prior to calling ILexerAction.Execute(Antlr4.Runtime.Lexer) on a position-dependent action. Before the method returns, the input position will be restored to the same position it was in when the method was invoked.

public Execute ( Lexer lexer, ICharStream input, int startIndex ) : void
lexer Lexer The lexer instance.
input ICharStream /// The input stream which is the source for the current token. /// When this method is called, the current /// /// for /// /// should be the start of the following token, i.e. 1 /// character past the end of the current token. ///
startIndex int /// The token start index. This value may be passed to /// /// to set the /// /// position to the beginning /// of the token. ///
