Constructor Details

ReadOnlySetProperty

public ReadOnlySetProperty()

The constructor of ReadOnlySetProperty.

Method Details

bindContentBidirectional

public void bindContentBidirectional(ObservableSet<E> set)

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

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

Parameters:: set - the ObservableSet this property should be bound to
Throws:: NullPointerException - if set is null; IllegalArgumentException - if set is the same set that this ReadOnlySetProperty points to

unbindContentBidirectional

public void unbindContentBidirectional(Object object)

Deletes a bidirectional content binding between the ObservableSet, that is wrapped in this ReadOnlySetProperty, 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 set that this ReadOnlySetProperty points to

bindContent

public void bindContent(ObservableSet<E> set)

Creates a content binding between the ObservableSet, that is wrapped in this ReadOnlySetProperty, and another ObservableSet.

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

Parameters:: set - the ObservableSet this property should be bound to
Throws:: NullPointerException - if set is null; IllegalArgumentException - if set is the same set that this ReadOnlySetProperty points to

unbindContent

public void unbindContent(Object object)

Deletes a content binding between the ObservableSet, that is wrapped in this ReadOnlySetProperty, 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 set that this ReadOnlySetProperty points to

hashCode

public int hashCode()

Returns a hash code for this ReadOnlySetProperty object.

Specified by:: hashCode in interface Collection<E>
Specified by:: hashCode in interface Set<E>
Overrides:: hashCode in class Object
Returns:: a hash code for this ReadOnlySetProperty object.

toString

public String toString()

Returns a string representation of this ReadOnlySetProperty object.

Overrides:: toString in class Object
Returns:: a string representation of this ReadOnlySetProperty object.
