The InvalidRegex exception class describes an exception associated with an invalid Regular Expression being passed to a method that takes a regular expression argument.
To produce an InvalidRegex exception yourself, you typically use a User Language Throw statement with an InvalidRegex New constructor. This statement must be issued from within a method, and it can only be caught by the code that calls the method. For example, the following statement throws an InvalidRegex exception with the position set to 13, the code set to 666, and the description indicating Bad luck:
throw %(invalidRegex):new(position=13, code=666, - description='Bad luck')
