Abstract

Processing an event signifying a condition in a computer system is described. The computer system maintains an invocation stack which includes a plurality of stack frames. Such event processing operates by selecting a stack frame from the invocation stack, and then determining whether a user specified event processing procedure capable of processing the event has been registered with the selected stack frame. If a user specified event processing procedure has been so registered, then the event is processed using the user specified event processing procedure as specified by a set of rules and options defined for the disposition and/or processing of the specific event. Optionally, it is then determined whether a language specific event processing procedure capable of processing the event has been registered with the selected stack frame. If a language specific event processing procedure has been so registered, then the event is processed using the language specific event processing procedure as specified by a set of rules and options defined for the disposition and/or processing of the specific event. If an user specified event processing procedure capable of processing the event or a language specific event processing procedure capable of processing the event has not been registered with any stack frame of the invocation stack or have chosen not to terminate the event processing, then the event is processed using an applicable default event processing procedure.
