Interface ObjectManager

All Known Implementing Classes:

DSpaceObjectManager

public interface ObjectManager

The object manager is a class that must be implemented by each specific repository implementation that identifies referenced objects. Since the DRI document includes references to external resources implementers of this class must know how objects are referenced. The specefic implementation of ObjectManager that is used is determened by the WingComponent that is creating the reference.
