Class AbstractContainer

java.lang.Object
  com.vaadin.data.util.AbstractContainer

All Implemented Interfaces:

Container, Serializable

Direct Known Subclasses:

AbstractInMemoryContainer

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(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.

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 -

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.
