Method Detail

bindContentBidirectional

public void bindContentBidirectional(ObservableMap<K,V> map)

Creates a bidirectional content binding of the ObservableMap, that is wrapped in this ReadOnlyMapProperty, and another ObservableMap.

A bidirectional content binding ensures that the content of two ObservableMaps is the same. If the content of one of the maps changes, the other one will be updated automatically.

Parameters:

map - the ObservableMap this property should be bound to

Throws:

NullPointerException - if map is null

IllegalArgumentException - if map is the same map that this ReadOnlyMapProperty points to

unbindContentBidirectional

public void unbindContentBidirectional(Object object)

Deletes a bidirectional content binding between the ObservableMap, that is wrapped in this ReadOnlyMapProperty, and another Object.

Parameters:

object - the Object to which the bidirectional binding should be removed

Throws:

NullPointerException - if object is null

IllegalArgumentException - if object is the same map that this ReadOnlyMapProperty points to

bindContent

public void bindContent(ObservableMap<K,V> map)

Creates a content binding between the ObservableMap, that is wrapped in this ReadOnlyMapProperty, and another ObservableMap.

A content binding ensures that the content of the wrapped ObservableMaps is the same as that of the other map. If the content of the other map changes, the wrapped map will be updated automatically. Once the wrapped list is bound to another map, you must not change it directly.

Parameters:

map - the ObservableMap this property should be bound to

Throws:

NullPointerException - if map is null

IllegalArgumentException - if map is the same map that this ReadOnlyMapProperty points to

unbindContent

public void unbindContent(Object object)

Deletes a content binding between the ObservableMap, that is wrapped in this ReadOnlyMapProperty, and another Object.

Parameters:

object - the Object to which the binding should be removed

Throws:

NullPointerException - if object is null

IllegalArgumentException - if object is the same map that this ReadOnlyMapProperty points to

hashCode

public int hashCode()

Returns a hash code for this ReadOnlyMapProperty object.

Specified by:

hashCode in interface Map<K,V>

Overrides:

hashCode in class Object

Returns:

a hash code for this ReadOnlyMapProperty object.

See Also:

Object.equals(java.lang.Object), System.identityHashCode(java.lang.Object)

toString

public String toString()

Returns a string representation of this ReadOnlyMapProperty object.

Overrides:

toString in class Object

Returns:

a string representation of this ReadOnlyMapProperty object.
