Examples of ObjectManager

gov.nasa.arc.mct.components.ObjectManager
Some components are capable of aggregating modifications made to other objects, typically in support of "Save All." Since the "All" in "Save All" may vary from view to view and component to component, this is communicated through a capability. ObjectManager instances must be available from {@link gov.nasa.arc.mct.components.AbstractComponent#getCapability(Class)}. @author vwoeltje

Definition of an ObjectManager. Provides the basics of object persistence internally, upon which are built javax.jdo.PersistenceManager and javax.persistence.EntityManager.
org.dspace.app.xmlui.wing.ObjectManager
The object manager is a class that must be implemented by each specific repository implementation that identifies refrenced objects. Since the DRI document includes refrences to external resources implementers of this class must know how objects are refrenced. The specefic implementation of ObjectManager that is used is determened by the WingComponent that is creating the refrence. @author Scott Phillips
