Module javafx.base

Class MapExpression<K,​V>

Type Parameters:
K - the type of the key elements
V - the type of the value elements
All Implemented Interfaces:
Map<K,​V>, Observable, ObservableMapValue<K,​V>, ObservableObjectValue<ObservableMap<K,​V>>, ObservableValue<ObservableMap<K,​V>>, ObservableMap<K,​V>
Direct Known Subclasses:
MapBinding, ReadOnlyMapProperty

public abstract class MapExpression<K,​V>
extends Object
implements ObservableMapValue<K,​V>
MapExpression is an ObservableMapValue plus additional convenience methods to generate bindings in a fluent style.

A concrete sub-class of MapExpression has to implement the method ObservableObjectValue.get(), which provides the actual value of this expression.

If the wrapped list of a MapExpression is null, all methods implementing the Map interface will behave as if they were applied to an immutable empty list.
