Package org.eclipse.gef.common.beans.binding

Class MultisetBinding<E>

java.lang.Object

org.eclipse.gef.common.beans.binding.MultisetExpression<E>

org.eclipse.gef.common.beans.binding.MultisetBinding<E>

Type Parameters:

E - The element type of the ObservableMultiset.

All Implemented Interfaces:

Multiset<E>, Iterable<E>, Collection<E>, Binding<ObservableMultiset<E>>, Observable, ObservableObjectValue<ObservableMultiset<E>>, ObservableValue<ObservableMultiset<E>>, ObservableMultisetValue<E>, ObservableMultiset<E>

public abstract class MultisetBinding<E>
extends MultisetExpression<E>
implements Binding<ObservableMultiset<E>>

An abstract base class that provides functionality needed to realize a Binding on an ObservableMultiset.

This class provides identical functionality for Multiset as MapBinding for Map, SetBinding for Set, or ListBinding for List.

Property Details

empty

public ReadOnlyBooleanProperty emptyProperty

Specified by:

emptyProperty in class MultisetExpression<E>

Returns:

A read-only property.

size

public ReadOnlyIntegerProperty sizeProperty

Specified by:

sizeProperty in class MultisetExpression<E>

Returns:

A read-only property.

Constructor Details

MultisetBinding

public MultisetBinding()

Method Details

addListener

public void addListener(ChangeListener<? super ObservableMultiset<E>> listener)

Specified by:

addListener in interface ObservableValue<E>

addListener

public void addListener(InvalidationListener listener)

Specified by:

addListener in interface Observable

addListener

public void addListener(MultisetChangeListener<? super E> listener)

Description copied from interface: ObservableMultiset

Adds a MultisetChangeListener to this ObservableMultiset. If the same listener is registered more than once, it will be notified more than once.

Specified by:

addListener in interface ObservableMultiset<E>

Parameters:

listener - The MultisetChangeListener to add.

bind

protected void bind(Observable... dependencies)

Start observing the given dependencies for changes. If the value of one of the dependencies changes, the binding is marked as invalid.

Parameters:

dependencies - The dependencies to observe.

computeValue

protected abstract ObservableMultiset<E> computeValue()

Computes the current value of this MultisetBinding.

Returns:

The current value of this MultisetBinding.

dispose

public void dispose()

Specified by:

dispose in interface Binding<E>

emptyProperty

public ReadOnlyBooleanProperty emptyProperty()

Description copied from class: MultisetExpression

A boolean property that reflects whether the Multiset is empty.

Specified by:

emptyProperty in class MultisetExpression<E>

Returns:

A read-only property.

fireValueChangedEvent

protected void fireValueChangedEvent()

Fires notifications to all attached InvalidationListeners, ChangeListeners, and SetMultimapChangeListeners.

fireValueChangedEvent

protected void fireValueChangedEvent(MultisetChangeListener.Change<? extends E> change)

Fires notifications to all attached InvalidationListeners, ChangeListeners, and MultisetChangeListeners.

Parameters:

change - the change that needs to be propagated

get

public ObservableMultiset<E> get()

Specified by:

get in interface ObservableObjectValue<E>

getDependencies

public ObservableList<?> getDependencies()

Specified by:

getDependencies in interface Binding<E>

invalidate

public void invalidate()

Specified by:

invalidate in interface Binding<E>

invalidated

protected void invalidated()

Can be overwritten by subclasses to receive invalidation notifications. Does nothing by default.

isValid

public boolean isValid()

Specified by:

isValid in interface Binding<E>

removeListener

public void removeListener(ChangeListener<? super ObservableMultiset<E>> listener)

Specified by:

removeListener in interface ObservableValue<E>

removeListener

public void removeListener(InvalidationListener listener)

Specified by:

removeListener in interface Observable

removeListener

public void removeListener(MultisetChangeListener<? super E> listener)

Description copied from interface: ObservableMultiset

Removes a MultisetChangeListener from this ObservableMultiset. Will do nothing if the listener was not attached to this ObservableMultiset. If it was added more than once, then only the first occurrence will be removed.

Specified by:

removeListener in interface ObservableMultiset<E>

Parameters:

listener - The MultisetChangeListener to remove.

sizeProperty

public ReadOnlyIntegerProperty sizeProperty()

Description copied from class: MultisetExpression

An integer property that represents the size of the Multiset.

Specified by:

sizeProperty in class MultisetExpression<E>

Returns:

A read-only property.

unbind

protected void unbind(Observable... dependencies)

Stops observing the dependencies for changes. The binding will no longer be marked as invalid if one of the dependencies changes.

Parameters:

dependencies - The dependencies to stop observing.
