public class PropertiesMergeModel
extends java.util.Observable

This is the model for resolving conflicts in the properties of the OsmPrimitives. In particular, it represents conflicts in the coordinates of Nodes and the deleted or visible state of OsmPrimitives. This model is an Observable. It notifies registered Observers whenever the internal state changes. This model also emits property changes for RESOLVED_COMPLETELY_PROP. Property change listeners may register themselves using addPropertyChangeListener(PropertyChangeListener).
