ObservableMap

public interface ObservableMap
implements Map

android.databinding.ObservableMap

Known Indirect Subclasses

A Map that notifies when items change. This kind of Map may be data bound and have the UI update as the map changes.

Implementers must call onMapChanged(ObservableMap, Object) whenever an item is added, changed, or removed.

ObservableArrayMap is a convenient implementation of ObservableMap. MapChangeRegistry may help other implementations manage the callbacks.
