boolean	addAll(E... elements) A convenient method for var-arg adding of elements.
void	addListener(ListChangeListener<? super E> listener) Add a listener to this observable list.
default FilteredList<E>	filtered(Predicate<E> predicate) Creates a FilteredList wrapper of this list using the specified predicate.

boolean	setAll(Collection<? extends E> col) Clears the ObservableList and add all elements from the collection.
boolean	setAll(E... elements) Clears the ObservableList and add all the elements passed as var-args.
default SortedList<E>	sorted() Creates a SortedList wrapper of this list with the natural ordering.
default SortedList<E>	sorted(Comparator<E> comparator) Creates a SortedList wrapper of this list using the specified comparator.

Method Detail

addListener

void addListener(ListChangeListener<? super E> listener)

Add a listener to this observable list.

Parameters:

listener - the listener for listening to the list changes

removeListener

void removeListener(ListChangeListener<? super E> listener)

Tries to removed a listener from this observable list. If the listener is not attached to this list, nothing happens.

Parameters:

listener - a listener to remove

addAll

boolean addAll(E... elements)

A convenient method for var-arg adding of elements.

Parameters:

elements - the elements to add

Returns:

true (as specified by Collection.add(E))

setAll

boolean setAll(E... elements)

Clears the ObservableList and add all the elements passed as var-args.

Parameters:

elements - the elements to set

Returns:

true (as specified by Collection.add(E))

Throws:

NullPointerException - if the specified arguments contain one or more null elements

setAll

boolean setAll(Collection<? extends E> col)

Clears the ObservableList and add all elements from the collection.

Parameters:

col - the collection with elements that will be added to this observableArrayList

Returns:

true (as specified by Collection.add(E))

Throws:

NullPointerException - if the specified collection contains one or more null elements

removeAll

boolean removeAll(E... elements)

A convenient method for var-arg usage of removaAll method.

Parameters:

elements - the elements to be removed

Returns:

true if list changed as a result of this call

retainAll

boolean retainAll(E... elements)

A convenient method for var-arg usage of retain method.

Parameters:

elements - the elements to be retained

Returns:

true if list changed as a result of this call

remove

void remove(int from,
            int to)

Basically a shortcut to sublist(from, to).clear() As this is a common operation, ObservableList has this method for convenient usage.

Parameters:

from - the start of the range to remove (inclusive)

to - the end of the range to remove (exclusive)

Throws:

IndexOutOfBoundsException - if an illegal range is provided

filtered

default FilteredList<E> filtered(Predicate<E> predicate)

Creates a FilteredList wrapper of this list using the specified predicate.

Parameters:

predicate - the predicate to use

Returns:

new FilteredList

Since:

JavaFX 8.0

sorted

default SortedList<E> sorted(Comparator<E> comparator)

Creates a SortedList wrapper of this list using the specified comparator.

Parameters:

comparator - the comparator to use or null for unordered List

Returns:

new SortedList

Since:

JavaFX 8.0

sorted

default SortedList<E> sorted()

Creates a SortedList wrapper of this list with the natural ordering.

Returns:

new SortedList

Since:

JavaFX 8.0
