Detailed Description

A facade to the functionality of the Event Scheduler.

Every public operation against the scheduler has to be executed via the interface provided by a static method of this class. No instance of this class is ever created and it has no non-static data members.

The life cycle of the Events module is the following:

At server start up: init_mutexes() -> init() When the server is running: create_event(), drop_event(), start_or_stop_event_scheduler(), etc At shutdown: deinit(), destroy_mutexes().

The peculiar initialization and shutdown cycle is an adaptation to the outside server startup/shutdown framework and mimics the rest of MySQL subsystems (ACL, time zone tables, etc).

The documentation for this class was generated from the following files:
