The handler command modifies event handlers (enable, disable, and such). It has identical syntax and identical functionality in native mode and in Java mode.
A handler is created for each event that needs to be managed in a debugging session. The commands trace, stop, and when create handlers. Each of these commands returns a number known as the handler ID (handler-ID). The handler, status, and delete commands manipulate or provide information about handlers in a generic fashion.
Either enable or disable given handlers, specify handler-ID as all for all handlers. Use $firedhandlers instead of handler-ID to disable the handlers that caused the most recent stoppage.
Print value of trip counter for given handler.
If a new limit parameter is specified, set new count limit for given event.
Reset trip counter for given handler.
where:
handler-ID is the identifier of a handler.
