Detailed Description

template<typename A = void>
class berry::Message< A >

Event/message/notification class.

This class allows one class to send out messages and another class to receive these message. There are subclasses for sending parameters along with the messages.

This is an implementation of the Observer pattern.

• There is no guarantee about the order of which observer is notified first. At the moment the observers which register first will be notified first.
• Notifications are synchronous, by direct method calls. There is no support for asynchronous messages.
