Method Detail

### fieldModified

    public void fieldModified(PersistenceField field,
                              int[] indices,
                              Transaction t)

  Specified by:
    `fieldModified` in interface `Manageable`

### getGraph

    public abstract Graph getGraph(View view)

  Returns the graph described by this descriptor, given the context `view`.

  Parameters:
    `view` - the context for the graph
  Returns:
    graph corresponding to this descriptor

### getPathFor

    public Path getPathFor(View view,
                           GraphState gs,
                           java.lang.Object obj,
