Class ViewDeclarationLanguageFactory

java.lang.Object

javax.faces.view.ViewDeclarationLanguageFactory

All Implemented Interfaces:

FacesWrapper<ViewDeclarationLanguageFactory>

public abstract class ViewDeclarationLanguageFactory
extends Object
implements FacesWrapper<ViewDeclarationLanguageFactory>

ViewDeclarationLanguageFactory is a factory object that creates (if needed) and returns a new ViewDeclarationLanguage instance based on the VDL found in a specific view.

There must be one ViewDeclarationLanguageFactory instance per web application that is utilizing Jakarta Server Faces. This instance can be acquired, in a portable manner, by calling:

   ViewDeclarationLanguageFactory factory = (ViewDeclarationLanguageFactory)
    FactoryFinder.getFactory(FactoryFinder.VIEW_DECLARATION_LANGUAGE_FACTORY);
 

Usage: extend this class and push the implementation being wrapped to the constructor and use getWrapped() to access the instance being wrapped.

Since:

2.0
