ContainerOrderedWrapper (vaadin-server 7.7.24 API)

java.lang.Object
- com.vaadin.data.util.ContainerOrderedWrapper

All Implemented Interfaces:

Container, Container.ItemSetChangeNotifier, Container.Ordered, Container.PropertySetChangeNotifier, Serializable

Direct Known Subclasses:

HierarchicalContainerOrderedWrapper
```
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.

Since:

3.0

    Specified by:
    
    containsId in interface Container
    
    Parameters:
    
    itemId - ID the of Item to be tested

  - getItem
```
public Item getItem(Object itemId)
```
    Description copied from interface: Container
    
    Gets the Item 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.
    
    Specified by:
    
    getItem in interface Container
    
    Parameters:
    
    itemId - ID of the Item to retrieve
    
    Returns:
    
    the Item with the given ID or null if the Item is not found in the Container

```
    Description copied from interface: Container
    
    Gets the ID's of all visible (after filtering and sorting) Items stored in the Container. The ID's cannot be modified through the returned collection.
    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.
    
    Specified by:
    
    getItemIds in interface Container
    
    Returns:
    
    unmodifiable collection of Item IDs
