You mean this object (class) contains this function? And in this class you have put some code in the Error() event to handle and log errors?

If yes then the Error() event for this class will trigger automatically if the function (method) produces an error.

And in addition to the other replies, if the function is contained in another object (class) what you can do is instead of having two objects (classes) have the second class inherit from the class with the error handler (and any class where you want to implement this error event), and in this way it will have this functionality built-in.
