ObservableMap

public interface ObservableMap
implements Map<K, V>

android.databinding.ObservableMap<K, V>

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.

void addOnMapChangedCallback (OnMapChangedCallback<? extends ObservableMap<K, V>, K, V> callback)

Adds a callback to listen for changes to the ObservableMap.

Parameters
`callback`	`OnMapChangedCallback`: The callback to start listening for events.

void removeOnMapChangedCallback (OnMapChangedCallback<? extends ObservableMap<K, V>, K, V> callback)

Removes a previously added callback.

Parameters
`callback`	`OnMapChangedCallback`: The callback that no longer needs to be notified of map changes.
