Class EdgeClassProxy

java.lang.Object
  i3.dragos.gm.core.proxy.GraphEntityClassProxy
      i3.dragos.gm.core.proxy.EdgeClassProxy

All Implemented Interfaces:

EdgeClass, ExistenceCheckable, GraphEntityClass, MetaAttributable

public class EdgeClassProxy
extends GraphEntityClassProxy
implements EdgeClass

An EdgeClassProxy delegates all method calls to the underlying edge class except for those that access fields which are used after an edge class has been deleted.
