Method Detail

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 call ClassDescriptor.getSubclassDescriptor(Class) before using the descriptor to access objects.

isFault

boolean isFault(java.lang.Object target)

Returns whether a target node connected to a given object is an unresolved fault.
