E - the type of the List elements.public abstract class ListExpression<E> extends Object implements ObservableListValue<E>
ListExpression is a
ObservableListValue plus additional convenience
methods to generate bindings in a fluent style.
A concrete sub-class of ListExpression has to implement the method
ObservableObjectValue.get(), which provides the
actual value of this expression.
If the wrapped list of a ListExpression is null, all methods implementing the List
interface will behave as if they were applied to an immutable empty list.

addAll(E... elements)
A convenient method for var-arg adding of elements.

listExpression(ObservableListValue<E> value)
Returns a
ListExpression that wraps a
ObservableListValue. |

remove(int i) |
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.

remove(Object obj) |
boolean |
removeAll(Collection<?> objects) |
boolean |
removeAll(E... elements)
A convenient method for var-arg usage of removaAll method.
|
boolean |
retainAll(Collection<?> objects) |
boolean |
retainAll(E... elements)
A convenient method for var-arg usage of retain method.
|
E |
set(int i,
E element) |
boolean |
setAll(Collection<? extends E> elements)
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.
|

size() |
abstract ReadOnlyIntegerProperty |
sizeProperty()
An integer property that represents the size of the list.
