Class ListEditor<T,E extends Editor<? super T>>
T - The type of data being managedE - The type of Editorpublic class ListEditor<T,E extends Editor<? super T>> extends Object implements CompositeEditor<List<T>,T,E>
The ListEditor will have no backing list until setValue(List) is
called with a non-null value.

Create a ListEditor backed by an EditorSource.
|
void |
onPropertyChange(String... paths)
Notifies the Editor that one or more value properties have changed.

The returned list will be live until the next call to setValue(List)
and shouldn't be used after that. Editors might (or might not) be reused
after a call to setValue(List).
If there is no backing list, an empty list will be returned.
Editors of type Epublic List<T> getList()
The structure of the List may be mutated arbitrarily, subject to the
limitations of the backing List, but the elements themselves should not
be mutated except through getEditors() to avoid data
inconsistency.
Returns null if there is no backing list, and edits cannot be made.
