Method Detail

getElements
public Object[] getElements()
Return the contents of the model.- Returns:
- the array of elements
-
set
public void set(Object[] newContents)
Sets the contents to the given array of elements- Parameters:
newContents
- new contents of this set
-
clear
public void clear()
Empties the set
-
addAll
public void addAll(Object[] toAdd)
Adds the given elements to the set- Parameters:
toAdd
- elements to add
-
addAll
public void addAll(Collection toAdd)
Adds the given elements to the set. Duplicate elements are ignored.- Parameters:
toAdd
- elements to add
-
changeAll
public void changeAll(Object[] changed)
Fires a change notification for all elements in the given array- Parameters:
changed
- array of elements that have changed
-
removeAll
public void removeAll(Object[] toRemove)
Removes all of the given elements from the set.- Parameters:
toRemove
- elements to remove
-
requestUpdate
public void requestUpdate(IConcurrentModelListener listener)
Description copied from interface:IConcurrentModel
Requests that the receiver to call the given listener's setContents(...) method at its earliest convenience. The receiver is allowed to compute the elements asynchronously. That is, it can compute the result in a background thread and call setContents(...) once the result is ready. If the result is too large to return in one batch, it can call setContents with an empty array followed by a sequence of adds.Has no effect if an update is already queued for an identical listener.
- Parameters:
listener
- listener whose setContents method should be called. The listener must have been previously registered with addListener.
