Detailed Description

Manager observer class.

Library: ilvmgr

This abstract class provides the infrastructure to receive notifications from an IlvManager instance. Subclasses must redefine the virtual member function IlvObserver::update where they can react to notifications sent by the manager.
During the notification, the only argument passed to IlvObserver::update is a pointer to a subclass of IlvManagerMessage. The IlvManagerMessage::_reason data member indicates the type of notification and which subclass the manager message belongs to.
A manager observer has an interest mask which is a bitwise OR combination of manager message categories. Each message category groups one or several message type (or reason). The interest mask determines the type of messages that the manager will sent to the observer and the ones that will be discarded.
