org.eclipse.persistence.descriptors.changetracking.MapChangeEvent
Purpose: Define a change event for Map types.
Description: For any object that wishes to use either object change tracking or attribute change tracking, its map attributes need to fire MapChangeEvent in the put or remove methods. In the case of a replace (ie key already exists) both a remove for that key and a put using the new value and old key must be fired.
Responsibilities: Create a MapChangeEvent for an object
