javafx.collections.transformation.SortedList<E>

Type Parameters:

E - the list element type

All Implemented Interfaces:

Iterable<E>, Collection<E>, List<E>, SequencedCollection<E>, Observable, ObservableList<E>

public final class SortedList<E>
extends TransformationList<E,E>

Wraps an ObservableList and sorts its content. All changes in the ObservableList are propagated immediately to the SortedList. Note: invalid SortedList (as a result of broken comparison) doesn't send any notification to listeners on becoming valid again.

Since:

JavaFX 8.0

Property Details

comparator

public final ObjectProperty<Comparator<? super E>> comparatorProperty

Constructor Details

SortedList

public SortedList(ObservableList<? extends E> source,

comparator - a comparator to use or null for unordered List

SortedList

public SortedList(ObservableList<? extends E> source)

Constructs a new unordered SortedList wrapper around the source list.

Parameters:

source - the source list
