)

Parameters

name

The Symbol.Name of the new symbol.

value

The text which must be matched for the terminal symbol to be recognized within the text. If null, the name will be used as the value.

comparison

Indicates how the text should be interpreted: as a case-sensitive literal string, a case-insensitive literal string, or a regular expression.

isExitSymbol

Indicates whether the symbol should be an exit symbol for the lexer state.

Return Value

If the LexerState owning the collection is not the default lexer state, the symbol can optionally be added as an exit symbol. If it is an exit symbol, the lexer state will be exited when tokens associated with the symbol are created by the lexer. When a lexer state is exited, the lexer will go back to the state it was in before the state was entered. A LexerState will be entered when a token is created which is associated with a TerminalSymbol that has a TerminalSymbol.LexerStateToEnter set. If a TerminalSymbol is both an exit symbol and it has a LexerStateToEnter set, the LexerStateToEnter will be ignored. The lexer cannot enter and exit a state at the same time and exiting a lexer state takes precedence.
