net.helipilot50.stocktrade.displayproject.binding.value.ValueModel
Describes models with a generic access to a single value that allow to observe value changes. The value can be accessed using the #getValue()/#setValue(Object) methods. Observers can register instances of PropertyChangeListener to be notified if the value changes.
If the value is read-only or write-only, an implementor may choose to reject an operation using an UnsupportedOperationException or may do nothing or perform an appropriate action, or may return an appropriate value.
The listeners registered with this ValueModel using #addValueChangeListener will be invoked only with PropertyChangeEvents that have the name set to "value". In other words, the listeners won't get notified when a PropertyChangeEvent is fired that has a null object as the name to indicate an arbitrary set of the event source's properties have changed. This is the case if you use the PropertyChangeSupport, either directly or indirectly, to fire property changes with the property name "value" specified. This constraint ensures that all ValueModel implementors behave like the AbstractValueModel subclasses. In the rare case, where you want to notify a PropertyChangeListener even with PropertyChangeEvents that have no property name set, you can register the listener with #addPropertyChangeListener, not #addValueChangeListener.
AbstractValueModel minimizes the effort required to implement this interface. It uses the PropertyChangeSupport to fire PropertyChangeEvents, and it adds PropertyChangeListeners for the specific property name "value". This ensures that the constraint mentioned above is met.
Implementors are encouraged to provide non-null values for the PropertyChangeEvent's old and new values. However, both may be null. @author Karsten Lentzsch @version $Revision: 1.8 $ @see AbstractValueModel @see ValueHolder @see net.helipilot50.stocktrade.displayproject.binding.beans.PropertyAdapter Copyright (c) 2002-2005 JGoodies Karsten Lentzsch.
