ExceptionEvent Class
public method Fire()
Parameters
None
Return Value
None
Description
This method initiates Aztec exception handling at the point where this method. The VM searches for an exceptions/handle block for a match with the type of exception being fired. If found, control is transferred to that construct (per standard Aztec exception handling rules). If not found, then an unhandled exception run-time error occurs.
In addition, if one or more Exception handlers are registered with the thread where the exception was fired, then standard Aztec event handling can proceed using the exception event object (if it passes the "filter"). If the thread which registered the handler is different than the thread where it was fired, the event will be processed by that thread at the same time that this thread processes the exceptions/handle construct.
