Class MultisetPropertyBase<E>

java.lang.Object

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

org.eclipse.gef.common.beans.property.ReadOnlyMultisetProperty<E>

org.eclipse.gef.common.beans.property.MultisetProperty<E>

org.eclipse.gef.common.beans.property.MultisetPropertyBase<E>

Type Parameters:

E - The element type of the wrapped ObservableMultiset.

All Implemented Interfaces:

Multiset<E>, Iterable<E>, Collection<E>, Observable, Property<ObservableMultiset<E>>, ReadOnlyProperty<ObservableMultiset<E>>, ObservableObjectValue<ObservableMultiset<E>>, ObservableValue<ObservableMultiset<E>>, WritableObjectValue<ObservableMultiset<E>>, WritableValue<ObservableMultiset<E>>, ObservableMultisetValue<E>, WritableMultisetValue<E>, ObservableMultiset<E>

Direct Known Subclasses:

SimpleMultisetProperty

public abstract class MultisetPropertyBase<E>
extends MultisetProperty<E>

Abstract base class for implementing a Property wrapping an ObservableMultiset.

This class provides identical functionality for Multiset as MapPropertyBase for Map, SetPropertyBase for Set, or ListPropertyBase for List.

Property Details

empty

public ReadOnlyBooleanProperty emptyProperty

Specified by:

emptyProperty in class MultisetExpression<E>

See Also:

• MultisetExpression.isEmpty()

size

public ReadOnlyIntegerProperty sizeProperty

Specified by:

sizeProperty in class MultisetExpression<E>

Constructor Details

MultisetPropertyBase

public MultisetPropertyBase()

Creates a new MultisetPropertyBase with no initial value.

MultisetPropertyBase

public MultisetPropertyBase(ObservableMultiset<E> initialValue)

Creates a new MultisetPropertyBase with the given ObservableMultiset as initial value.

Parameters:

initialValue - The initial value of the to be created MultisetPropertyBase.

Method Details

addListener

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

addListener

public void addListener(InvalidationListener listener)

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.

Parameters:

listener - The MultisetChangeListener to add.

appendValueToString

protected void appendValueToString(StringBuilder result)

Description copied from class: ReadOnlyMultisetProperty

Appends a representation of this SetMultimapProperty's value to the given StringBuilder. Gets called from ReadOnlyMultisetProperty.toString() to allow subclasses to provide a changed value representation.

Overrides:

appendValueToString in class ReadOnlyMultisetProperty<E>

Parameters:

result - A StringBuilder to append the value representation to.

bind

public void bind(ObservableValue<? extends ObservableMultiset<E>> observedValue)

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>

See Also:

• MultisetExpression.isEmpty()

fireValueChangedEvent

protected void fireValueChangedEvent()

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

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()

invalidated

protected void invalidated()

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

isBound

public boolean isBound()

removeListener

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

removeListener

public void removeListener(InvalidationListener listener)

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.

Parameters:

listener - The MultisetChangeListener to remove.

set

public void set(ObservableMultiset<E> newValue)

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>

unbind

public void unbind()
