Description

The AcDbObjectReactor class is used as the base class for reactor classes that override methods called for events for which notification is desired. When an object of one of these derived classes is instantiated and added to the reactor chain of the object for which notification is desired, then whenever the "notifying" object is accessed, the appropriate methods within the reactor object will be called.

Remarks

You use this class by defining a class that inherits from AcDbObjectReactor. You instantiate an object of the class derived from AcDbObjectReactor, and add the newly created reactor object to the reactor chain by calling the addReactor method of the object you want notification on.
