Interface NodeStateDiff

All Known Implementing Classes:

TraversingNodeDiffHandler

public interface NodeStateDiff

Handler of node state differences. The NodeStore.compare(NodeState, NodeState, NodeStateDiff) reports detected node state differences by calling methods of a handler instance that implements this interface. The compare method will go through all properties and child nodes of the two states, calling the relevant added, changed or deleted methods where appropriate. Differences in the ordering of properties or child nodes do not affect the comparison, and the order in which such differences are reported is unspecified.
