Examples of 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.

oracle.toplink.indirection.ValueHolder
org.apache.cayenne.ValueHolder
Provides a level of indirection for property value access, most often used for deferred faulting of to-one relationships. A ValueHolder abstracts how a property value is obtained (fetched from DB, etc.), thus simplifying design of an object that uses it.
Here is an example of a bean property implemented using ValueHolder:
```
 protected ValueHolder someProperty; public SomeClass getSomeProperty() { return (SomeClass) somePropertyHolder.getValue(SomeClass.class); } public void setSomeProperty(SomeClass newValue) { somePropertyHolder.setValue(SomeClass.class, newValue); } 
```

org.apache.drill.exec.expr.holders.ValueHolder
org.drools.ide.common.client.modeldriven.brl.templates.RuleModelPeerVariableVisitor.ValueHolder
org.eclipse.persistence.indirection.ValueHolder

Purpose: Act as a place holder for a variable that required a value holder interface. This class should be used to initialze an objects attributes that are using indirection is their mappings.

org.metawidget.statically.faces.component.ValueHolder
org.msgpack.value.holder.ValueHolder
This class can hold any message packed value.
org.openntf.formula.ValueHolder
This Valueholder is to hold single or multiple values. When evaluating a formula, every String/int/double value is wrapped in a "ValueHolder". The holder has several get-methods to return the different types. You always must check the datatype before calling one of the getters, because a ValueHolder that contains Strings cannot return The code itself might look strange, but this was done to be as fast as possible @author Roland Praml, Foconis AG
org.springframework.beans.factory.config.ConstructorArgumentValues.ValueHolder
org.springframework.binding.value.support.ValueHolder
A simple value model that contains a single value. Notifies listeners when the contained value changes. @author Keith Donald @author Karsten Lentzsch
