Remarks

The IObjectLayer interface declares the members that are common to all object access layers that provide means for sessions to interact with data access layers.

The following classes implement the IObjectLayer interface:

• SimpleObjectLayer - An object access layer that saves and loads persistent objects via a data access layer associated with a data store provider (an IDataStore implementation).
• SessionObjectLayer - An object access layer that saves and loads persistent objects via a parent Session or UnitOfWork.
• SerializableObjectLayerClient - An object access layer that saves and loads persistent objects via an object implementing the ISerializableObjectLayer interface.
