  com.vaadin.data.util.AbstractContainer

All Implemented Interfaces:

Container, Serializable

Direct Known Subclasses:

AbstractInMemoryContainer

public abstract class AbstractContainer
extends Object
implements Container

Abstract container class that manages event listeners and sending events to them (PropertySetChangeNotifier, ItemSetChangeNotifier). Note that this class provides the internal implementations for both types of events and notifiers as protected methods, but does not implement the PropertySetChangeNotifier and ItemSetChangeNotifier interfaces directly. This way, subclasses can choose not to implement them. Subclasses implementing those interfaces should also override the corresponding #addListener() and #removeListener() methods to make them public.

Since:

6.6

fireContainerPropertySetChange

protected void fireContainerPropertySetChange()

Sends a simple Property set change event to all interested listeners.

fireContainerPropertySetChange

protected void fireContainerPropertySetChange(Container.PropertySetChangeEvent event)

Sends a Property set change event to all interested listeners. Use fireContainerPropertySetChange() instead of this method unless additional information about the exact changes is available and should be included in the event.

Parameters:

event - the property change event to send, optionally with additional information

fireItemSetChange

protected void fireItemSetChange()

Sends a simple Item set change event to all interested listeners, indicating that anything in the contents may have changed (items added, removed etc.).

fireItemSetChange

protected void fireItemSetChange(Container.ItemSetChangeEvent event)

Sends an Item set change event to all registered interested listeners.

Parameters:

event - the item set change event to send, optionally with additional information

setPropertySetChangeListeners

protected void setPropertySetChangeListeners(Collection<Container.PropertySetChangeListener> propertySetChangeListeners)

Sets the property set change listener collection. For internal use only.

Parameters:

propertySetChangeListeners -

getPropertySetChangeListeners

protected Collection<Container.PropertySetChangeListener> getPropertySetChangeListeners()

Returns the property set change listener collection. For internal use only.

setItemSetChangeListeners

protected void setItemSetChangeListeners(Collection<Container.ItemSetChangeListener> itemSetChangeListeners)

Sets the item set change listener collection. For internal use only.

Parameters:

itemSetChangeListeners -

getItemSetChangeListeners

protected Collection<Container.ItemSetChangeListener> getItemSetChangeListeners()

Returns the item set change listener collection. For internal use only.

getListeners
