Interface ModelChangedListener

All Known Implementing Classes:
ChangedListener, NullListener, ObjectListener, StatementListener
public interface ModelChangedListener
The interface for classes that listen for model-changed events. In all cases, the argument is [a copy of] the item that has been presented to the model, or its underlying graph, for addition or removal. For an add, the item [or parts of that item] may have already been present in the model; for remove, the item [or parts of it] need not have been absent from the item.

NOTE that the listener is supplied with more-or-less faithful copies of the original items that were added to, or removed from, the model. In particular, graph-level updates to the model appear as statements, not triples.
