getRelationship
ObjRelationship getRelationship()
Returns a relationship associated with this arc.- Since:
- 3.0
-
getComplimentaryReverseDbRelationshipPath
String getComplimentaryReverseDbRelationshipPath()
Returns a path over reverse DbRelationships for this arc's ObjRelationship.- Since:
- 4.0
-
getComplimentaryReverseArc
ArcProperty getComplimentaryReverseArc()
Returns a complimentary reverse ArcProperty or null if no reverse arc exists.
-
getTargetDescriptor
ClassDescriptor getTargetDescriptor()
Returns a ClassDescriptor for the type of graph nodes pointed to by this arc property. Note that considering that a target object may be a subclass of the class handled by the descriptor, users of this method may need to callClassDescriptor.getSubclassDescriptor(Class)
before using the descriptor to access objects.
-
isFault
boolean isFault(Object source)
Returns whether a target node connected to a given object is an unresolved fault.- Parameters:
source
- an object that is a source object of the relationship.
-
invalidate
void invalidate(Object object)
Turns a property of an object into a fault.- Since:
- 3.0
