im\util\EventHandler

---

Description

Defines a binary event handler.

This event handler uses binary event flags to define each event type. That means that each event type must be defined as $event = 1 << $x.

The event handler defines classes that provides events for internal tasks. It is not meant to be a global handler and as such it does not define any external dispatch features. Dispatching is an internal matter and the classes only provide external callback feature on events.
