Module ce_event

Super-simple generic synchronous event handler.

Description

Super-simple generic synchronous event handler.

This module differs from gen_event in several significant ways:

notify

each event (class, not instance) must have a unique name (event id)
fully synchronous (every event handler is executed in the process that causes the event)
each event is executed in order of its priority
each event handler can cancel all subsequent events and immediately return a value to the cause of the event

Event handlers are passed the state, initially given by the cause of the event. Each handler may return:

{ok, NewState} to change the state and continue processing this event with other handlers;
{done, NewState} to change the state and cancel the processing of the other handlers; or
{error, Error} to indicate an error occurred.
