org.eclipse.rse.core.model.RSEPersistableObject
      extended by 

org.eclipse.rse.core.model.PropertySetContainer
          extended by 

org.eclipse.rse.core.model.RSEModelObject
              extended by 
org.eclipse.rse.core.references.SystemReferencedObject
All Implemented Interfaces:
IPropertySetContainer, IRSEModelObject, IRSEPersistableContainer, IRSEBaseReferencedObject, IRSEReferencedObject

public abstract class SystemReferencedObject
extends RSEModelObject
implements IRSEReferencedObject

A class to encapsulate the operations required of an object which supports references to it by other objects ( SystemReferencingObject). This type of class needs to support maintaining an in-memory list of all who reference it so that list can be following on delete and rename operations.

Since:
org.eclipse.rse.core 3.0
