Field Detail

### complimentaryReverseArcName

    protected String complimentaryReverseArcName

### targetDescriptor

    protected ClassDescriptor targetDescriptor

### relationship

    protected ObjRelationship relationship

Constructor Detail

### BaseArcProperty

    public BaseArcProperty(ClassDescriptor owner,
                           ClassDescriptor targetDescriptor,
                           Accessor accessor,
                           String reverseName)

Method Detail

### visit

    public abstract boolean visit(PropertyVisitor visitor)

  Description copied from interface: `Property`
  A visitor accept method.

  Specified by:
    `visit` in interface `Property`
  Specified by:
    `visit` in class `BaseProperty`
  Returns:
    a status returned by the corresponding callback method of the visitor. It serves as an indication of whether peer properties processing is still needed.

### isFault

    public abstract boolean isFault(Object source)

  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`
  Parameters:
    `source` - an object that is a source object of the relationship.

### getRelationship

    public ObjRelationship getRelationship()

  Description copied from interface: `ArcProperty`
  Returns a relationship associated with this arc.

  Specified by:
    `getRelationship` in interface `ArcProperty`

### 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`

### setReverse

    protected void setReverse(Object source,
                              Object oldTarget,
                              Object newTarget)

  A convenience method to set the reverse arc used by subclasses.
