Detailed Description

Data provider interface definition.

The data provider interface allows to:

  • Define lists of items to be loaded automatically when a new root node is assigned to the data store.
  • Register objects from the data store. Once objects are registered with the data store the client gives up ownership.
  • Unregister objects from the data store. Unregistering an object means to actually delete all entries hanging below, not the object itself - since the client claims back ownership. Note that this is a very delicate operation - any reference to the object will be invalid. Even worse: invalid references cannot be detected.
  • Retrieve objects to the data store. Depending ont he availibility of the requested object in the data store the represented object will be loaded if possible.
  • Find objects beeing present in the store without actually creating the representation if the object is not present.
  • Create 'soft' links between objects in the transient store.
  • Request object updates.
  • Removed call to update registry entry state in the data service
