Method Details

add

public void add(int index,
 T element)

Specified by:

add in interface List<T>

Overrides:

add in class AbstractList<T>

get

public T get(int index)

Specified by:

get in interface List<T>

Specified by:

get in class AbstractList<T>

remove

public T remove(int index)

Specified by:

remove in interface List<T>

Overrides:

remove in class AbstractList<T>

set

public T set(int index,
 T element)

Specified by:

set in interface List<T>

Overrides:

set in class AbstractList<T>

size

public int size()

Specified by:

size in interface Collection<T>

Specified by:

size in interface List<T>

Specified by:

size in class AbstractCollection<T>

attach

void attach()

Must be called after construction. This is a two-phase initialization so that ListEditor can assign its list field before any sub-editors might call ListEditor.getList()

detach

void detach()

flush

void flush()

getEditors

List<? extends E> getEditors()

For testing only.

isSameValue

boolean isSameValue(List<T> value)

Checks whether that ListEditorWrapper can be reused for the passed list.

The ListEditorWrapper can be reused if and only if the backing list is the same instance as the passed list.

refresh

void refresh()

Refresh the editors in case the backing list has been modified from outside the ListEditorWrapper list.

This is basically the opposite from flush(). It's used to reuse sub-editors instead of recreating a ListEditorWrapper from scratch.
