K - the type of the key elements of the MapV - the type of the value elements of the Mappublic abstract class MapProperty<K,V> extends ReadOnlyMapProperty<K,V> implements Property<ObservableMap<K,V>>, WritableMapValue<K,V>
Property wrapping a
ObservableMap.
The value of a MapProperty can be get and set with ObservableObjectValue.get(),
MapExpression.getValue(), WritableObjectValue.set(Object), and setValue(javafx.collections.ObservableMap).
A property can be bound and unbound unidirectional with
Property.bind(javafx.beans.value.ObservableValue) and Property.unbind(). Bidirectional bindings
can be created and removed with bindBidirectional(Property) and
unbindBidirectional(Property).
The context of a MapProperty can be read with ReadOnlyProperty.getBean()
and ReadOnlyProperty.getName().ObservableMap,

Bidirectional bindings exists independently of unidirectional bindings. So it is possible to
add unidirectional binding to a property with bidirectional binding and vice-versa. However, this practice is
discouraged.
It is possible to have multiple bidirectional bindings of one Property.
JavaFX bidirectional binding implementation use weak listeners. This means bidirectional binding does not prevent properties from being garbage collected.

Property and another

If no bidirectional binding between the properties exists, calling this
method has no effect.
It is possible to unbind by a call on the second property. This code will work:
property1.bindBirectional(property2);
property2.unbindBidirectional(property1);
