Object used to create memory relationship class objects.
|IMemoryRelationshipClassFactory||Provides access to members that open a memory relationship class.|
A MemoryRelationshipClassFactory is an object that manages the MemoryRelationshipClasses that exist in the application. You must use either a MemoryRelationshipClassFactory or a MemoryRelationshipClassName object to create new MemoryRelationshipClasses.
Like WorkspaceFactory, a MemoryRelationshipClassFactory is a singleton object. This means that you can only have one instance of this object per COM STA apartment / per thread.
MemoryRelationshipClassFactory is the one and only instance of its class.
