 ListChangeListener.Change<? extends E> change)

Method Details

next

public boolean next()

Description copied from class: ListChangeListener.Change

Go to the next change. The Change in the initial state is invalid a requires a call to next() before calling other methods. The first next() call will make this object represent the first change.

Specified by:

next in class ListChangeListener.Change<E>

Returns:

true if switched to the next change, false if this is the last change.

reset

public void reset()

Description copied from class: ListChangeListener.Change

Reset to the initial stage. After this call, the next() must be called before working with the first change.

Specified by:

reset in class ListChangeListener.Change<E>

getTo

public int getTo()

Description copied from class: ListChangeListener.Change

The end of the change interval.

Specified by:

getTo in class ListChangeListener.Change<E>

Returns:

a end (exclusive) of an interval related to the change.

• ListChangeListener.Change.getFrom()

getRemoved

public List<E> getRemoved()

Description copied from class: ListChangeListener.Change

An immutable list of removed/replaced elements. If no elements were removed from the list, an empty list is returned.

Specified by:

getRemoved in class ListChangeListener.Change<E>

Returns:

a list with all the removed elements

getFrom

public int getFrom()

Description copied from class: ListChangeListener.Change

If wasAdded is true, the interval contains all the values that were added. If wasPermutated is true, the interval marks the values that were permutated. If wasRemoved is true and wasAdded is false, getFrom() and getTo() should return the same number - the place where the removed elements were positioned in the list.

Specified by:

getFrom in class ListChangeListener.Change<E>

Returns:

a beginning (inclusive) of an interval related to the change

wasUpdated

public boolean wasUpdated()

Description copied from class: ListChangeListener.Change

Indicates that the elements between getFrom() (inclusive) to getTo() exclusive has changed. This is the only optional event type and may not be fired by all ObservableLists.

Overrides:

wasUpdated in class ListChangeListener.Change<E>

Returns:

true if the current change is an update change.

getPermutation

protected int[] getPermutation()

Description copied from class: ListChangeListener.Change

If this change is an permutation, it returns an integer array that describes the permutation. This array maps directly from the previous indexes to the new ones. This method is not publicly accessible and therefore can return an array safely. The 0 index of the array corresponds to index ListChangeListener.Change.getFrom() of the list. The same applies for the last index and ListChangeListener.Change.getTo(). The method is used by ListChangeListener.Change.wasPermutated() and ListChangeListener.Change.getPermutation(int) methods.

Specified by:

getPermutation in class ListChangeListener.Change<E>

Returns:

empty array if this is not permutation or an integer array containing the permutation

toString

public String toString()

Overrides:

toString in class Object
