NSCoding
The EODisplayGoup keeps track of all enterprise objects from a particular EODataSource to coordinate their internal state with other objects such as UI elements and other EODisplayGroups. Commonly the data source is a EODatabaseDataSource (EOAccess) which manages the objects of a single entity for a specific editing context. The display group is connected to the UI elements or other display groups via EOAssociations. This framework is responsible to update the enterprise objects when the contents and state of the UI elements are changed and to update the UI elements when the state of the enterprise objects are changed.
