Class ExtensionObjectProxy<T>

java.lang.Object

de.intarsys.claptz.impl.ExtensionObjectProxy<T>

All Implemented Interfaces:

IElementConfigurable, IProxy<T>

public class ExtensionObjectProxy<T>
extends Object
implements IElementConfigurable, IProxy<T>

A generic implementation to ease implementation of "deferred" objects declared via an IExtension.

This object encapsulates the IExtension and the Element, preparing for realization of the intended object on demand. Two common scenarios are supported. In the first, the provider of the extension point itself creates the ExtensionObjectProxy directly to avoid the cost of reflective class access. In the second, a concrete factory object may be derived from ExtensionObjectProxy to inherit its lazyness with regard to hosting an object to be realized. The concrete proxy class name may be declared in an another element attribute than "class".
