public class ContainerOrderedWrapper extends Object implements Container.Ordered, Container.ItemSetChangeNotifier, Container.PropertySetChangeNotifier
A wrapper class for adding external ordering to containers not implementing
the Container.Ordered interface.
If the wrapped container is changed directly (that is, not through the
wrapper), and does not implement Container.ItemSetChangeNotifier and/or
Container.PropertySetChangeNotifier the hierarchy information must be updated
with the updateOrderWrapper() method.

Note : If the contents of the wrapped container change without the wrapper's knowledge, this method needs to be called to update the ordering information of the Items.

ContainerFiltering can hide items so that they will not be visible through the container API, and this method should respect visibility of items (i.e. only indicate visible items as being in the container) if feasible for the container.
containsId in interface ContaineritemId - ID the of Item to be testedpublic Item getItem(Object itemId)
ContainerItem with the given Item ID from the Container. If the
Container does not contain the requested Item, null is
returned.
Containers should not return Items that are filtered out.
public Collection<?> getItemIds()
Container
If the container is Container.Ordered, the collection returned by this
method should follow that order. If the container is Container.Sortable,
the items should be in the sorted order.
Calling this method for large lazy containers can be an expensive operation and should be avoided when practical.
