Class AbstractObservableSet<E>

java.lang.Object

java.util.AbstractCollection<E>

java.util.AbstractSet<E>

org.jhotdraw8.fxcollection.AbstractObservableSet<E>

Type Parameters:

E - the element type

All Implemented Interfaces:

Iterable<E>, Collection<E>, Set<E>, javafx.beans.Observable, javafx.collections.ObservableSet<E>, ReadOnlyCollection<E>, ReadOnlySet<E>

Direct Known Subclasses:

ModifiableObservableSet

public abstract class AbstractObservableSet<E>
extends AbstractSet<E>
implements javafx.collections.ObservableSet<E>, ReadOnlySet<E>

Abstract base class for ObservableSets. This implementation provides overridable fire methods, saving one level of indirection.

Method Details

add

public boolean add(E e)

Specified by:

add in interface Collection<E>

Specified by:

add in interface Set<E>

Overrides:

add in class AbstractCollection<E>

backingSetAdd

protected abstract boolean backingSetAdd(E e)

addAll

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

Specified by:

addAll in interface Collection<E>

Specified by:

addAll in interface Set<E>

Overrides:

addAll in class AbstractCollection<E>

addListener

public void addListener(javafx.beans.InvalidationListener listener)

Specified by:

addListener in interface javafx.beans.Observable

addListener

public void addListener(javafx.collections.SetChangeListener<? super E> listener)

Specified by:

addListener in interface javafx.collections.ObservableSet<E>

clear

public void clear()

Specified by:

clear in interface Collection<E>

Specified by:

clear in interface Set<E>

Overrides:

clear in class AbstractCollection<E>

stream

public Stream<E> stream()

Specified by:

stream in interface Collection<E>

Specified by:

stream in interface ReadOnlyCollection<E>

backingSetClear

protected abstract void backingSetClear()

backingSetToArray

protected abstract Object[] backingSetToArray()

contains

public boolean contains(@Nullable Object o)

Specified by:

contains in interface Collection<E>

Specified by:

contains in interface ReadOnlyCollection<E>

Specified by:

contains in interface Set<E>

Overrides:

contains in class AbstractCollection<E>

backingSetContains

protected abstract boolean backingSetContains(Object o)

containsAll

public boolean containsAll(Collection<?> c)

Specified by:

containsAll in interface Collection<E>

Specified by:

fireAdded

protected void fireAdded(@Nullable E e)

fireRemoved

protected void fireRemoved(@Nullable E e)

fireUpdated

public void fireUpdated(@Nullable E e)

invalidated

protected void invalidated()

The method invalidated() can be overridden to receive invalidation notifications. This is the preferred option in Objects defining the property, because it requires less memory.

The default implementation is empty.
