I'm trying to figure out how setting an exception object in the 'throws' property of an object function works.

Does it negate the need for a try/catch in the function?

What happens when a runtime error occurs? Is there an event or function in the exception object that gets called?

 

Context:

C++ program uses PBNI to instantiate a PB object and calls a function in it. Works great until there is an exception. From what I can tell exceptions don't pass back to the calling C++ code. The C++ program aborts if the exception isn't handled by the PB code. Currently using try/catch but would like to use something more 'behind the scenes'.
