Class Aggregate

java.lang.Object

java.util.Observable

com.codename1.rad.models.BaseEntity

com.codename1.rad.models.Aggregate

All Implemented Interfaces:

Entity, EntityWrapper, Iterable<Entity>

public class Aggregate
extends BaseEntity
implements Iterable<Entity>

A special type of Entity that helps to propagate changes from any entity in the aggregate to the aggregate root. This can be handy if there is a primary entity that contains some aggregated "sub-entities". The sub-entities cannot exist outside the context of their aggregate root, and changes to any of the sub-entities will imply that the root is dirty.
