Class AbstractContainer

  • All Implemented Interfaces:

    Container, Serializable

    Direct Known Subclasses:

    AbstractInMemoryContainer, GeneratedPropertyContainer


    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.

      • fireContainerPropertySetChange

        protected void fireContainerPropertySetChange()

      • 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.
