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

Class MultisetExpression<E>

java.lang.Object

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

Type Parameters:

E - The element type of the ObservableMultiset.

All Implemented Interfaces:

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

Direct Known Subclasses:

MultisetBinding, ReadOnlyMultisetProperty

public abstract class MultisetExpression<E>
extends Object
implements ObservableMultisetValue<E>

A SetMultimapExpression is a ObservableMultisetValue plus additional convenience methods to generate bindings.

This class provides identical functionality for Multiset as MapExpression for Map, SetExpression for Set, or ListExpression for List.

Property Details

empty

public abstract ReadOnlyBooleanProperty emptyProperty

A boolean property that reflects whether the Multiset is empty.

See Also:

• isEmpty()

size

public abstract ReadOnlyIntegerProperty sizeProperty

An integer property that represents the size of the Multiset.

Constructor Details

MultisetExpression

public MultisetExpression()

Method Details

multisetExpression

public static <E> MultisetExpression<E> multisetExpression(ObservableMultisetValue<E> multisetValue)

Returns a MultisetExpression that wraps an ObservableMultisetValue. If the ObservableMultisetValue is already a MultisetExpression, it will be returned. Otherwise a new concrete MultisetBinding is created that is bound to the ObservableMultisetValue.

Type Parameters:

E - The element type of the MultisetExpression.

Parameters:

multisetValue - The ObservableMultisetValue for which to return a MultisetExpression.

Returns:

The passed in ObservableMultisetValue if its already a MultisetExpression, or a newly created MultisetBinding for it.

add

public boolean add(E element)

Specified by:

add in interface Collection<E>

Specified by:

add in interface Multiset<E>

add

public int add(E element,
 int occurrences)

Specified by:

add in interface Multiset<E>

addAll

public boolean addAll(Collection<? extends E> c)

Specified by:

addAll in interface Collection<E>

asString

public StringBinding asString()

Creates a StringBinding that holds the value of the MultisetExpression turned into a String. If the value of this SetMultimapExpression changes, the value of the StringBinding will be updated automatically.

Returns:

A new StringBinding.

clear

public void clear()

Specified by:

clear in interface Collection<E>

contains

emptyProperty

public abstract ReadOnlyBooleanProperty emptyProperty()

A boolean property that reflects whether the Multiset is empty.

See Also:

• isEmpty()

entrySet

public Set<Multiset.Entry<E>> entrySet()

Specified by:
