ObservableMap

Class Overview

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.

Public Methods
abstract void	addOnMapChangedCallback(OnMapChangedCallback<? extends ObservableMap<K, V>, K, V> callback) Adds a callback to listen for changes to the ObservableMap.
abstract void	removeOnMapChangedCallback(OnMapChangedCallback<? extends ObservableMap<K, V>, K, V> callback) Removes a previously added callback.

Public Methods

abstract void

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

Adds a callback to listen for changes to the ObservableMap.

abstract void

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

Removes a previously added callback.

Inherited Methods

From interface java.util.Map

abstract void	clear() Removes all elements from this `Map`, leaving it empty.
abstract boolean	containsKey(Object key) Returns whether this `Map` contains the specified key.
abstract boolean	containsValue(Object value) Returns whether this `Map` contains the specified value.
abstract Set<Entry<K, V>>	entrySet() Returns a `Set` containing all of the mappings in this `Map`.
abstract boolean	equals(Object object) Compares the argument to the receiver, and returns `true` if the specified object is a `Map` and both `Map`s contain the same mappings.
abstract V	get(Object key) Returns the value of the mapping with the specified key.
abstract int	hashCode() Returns an integer hash code for the receiver.
abstract boolean	isEmpty() Returns whether this map is empty.
abstract Set<K>	keySet() Returns a set of the keys contained in this `Map`.
abstract V	put(K key, V value) Maps the specified key to the specified value.
abstract void	putAll(Map<? extends K, ? extends V> map) Copies every mapping in the specified `Map` to this `Map`.
abstract V	remove(Object key) Removes a mapping with the specified key from this `Map`.
abstract int	size() Returns the number of mappings in this `Map`.
abstract Collection<V>	values() Returns a `Collection` of the values contained in this `Map`.

Public Methods

Adds a callback to listen for changes to the ObservableMap.

callback	The callback to start listening for events.

Removes a previously added callback.

callback	The callback that no longer needs to be notified of map changes.
