Examples of DisplayProject.binding.value.ValueHolder

DisplayProject.binding.value.ValueHolder
A simple {@link DisplayProject.binding.value.ValueModel} implementation that holds a generic value. If the value changes, a PropertyChangeEvent is fired that can be observed using a PropertyChangeListener.
Differences in the old and new value can be checked either using == or #equals. The unbound property identityCheckEnabled determines which mechanism is used to check for changes in #setValue(Object). This check can be overriden for individual changes by the boolean parameter in #setValue(Object, boolean).
Constraints: The value is of type Object. @author Karsten Lentzsch @version $Revision: 1.8 $ @see ValueModel @see java.beans.PropertyChangeEvent @see java.beans.PropertyChangeListener @see DisplayProject.binding.beans.ExtendedPropertyChangeSupport Copyright (c) 2002-2005 JGoodies Karsten Lentzsch.
