CROSS-THREAD EXCEPTION HANDLING

摘要

A system for providing cross-exception event handling is provided. The system allows a source thread to throw an event (e.g., exception) as part of structured event handling of a programming language that specifies a target thread. When the event is thrown, the source thread starts a handler thread to handle the event in a current context of the target thread. The handler thread is passed an indication of the event and the target thread and sets its context to be consistent with that of handling events in the target thread. The handler thread then handles the event. The source thread may continue its execution in parallel or may terminate its execution as specified in a statement that threw the event. Execution of the target thread may be aborted and its execution continued at an exit statement of an enclosing structured event handling construct—as specified when the event was thrown.
