public boolean visit(PropertyVisitor visitor)

Specified by:

visit in interface Property

Overrides:

getComplimentaryReverseArc

public ArcProperty getComplimentaryReverseArc()

Description copied from interface: ArcProperty

Returns a complimentary reverse ArcProperty or null if no reverse arc exists.

Specified by:

getComplimentaryReverseArc in interface ArcProperty

getTargetDescriptor

public ClassDescriptor getTargetDescriptor()

Description copied from interface: ArcProperty

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.

Specified by:

getTargetDescriptor in interface ArcProperty

isFault

public abstract boolean isFault(java.lang.Object target)

Description copied from interface: ArcProperty

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

Specified by:

isFault in interface ArcProperty
