Interface GraphChangeHandler

All Known Implementing Classes:
ChildDiffLoader
public interface GraphChangeHandler
Defines callback API that can be used by object graph nodes to notify of their state changes. Graph nodes can be any objects as long as each node supports a notion of a unique id within the graph and each directional arc has a unique identifier within its source node.
