ViewDeclarationLanguageFactory

java.lang.Object
- javax.faces.view.ViewDeclarationLanguageFactory

All Implemented Interfaces:

FacesWrapper<ViewDeclarationLanguageFactory>
```
public abstract class ViewDeclarationLanguageFactory
extends java.lang.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

```
public ViewDeclarationLanguageFactory(ViewDeclarationLanguageFactory wrapped)
```
    If this factory has been decorated, the implementation doing the decorating should push the implementation being wrapped to this constructor. The getWrapped() will then return the implementation being wrapped.
    
    Parameters:
    
    wrapped - The implementation being wrapped.

```
public ViewDeclarationLanguageFactory getWrapped()
```
    If this factory has been decorated, the implementation doing the decorating may override this method to provide access to the implementation being wrapped.
    
    Specified by:
    
    getWrapped in interface FacesWrapper<ViewDeclarationLanguageFactory>
    
    Returns:
    
    the wrapped instance.
  - getViewDeclarationLanguage
```
public abstract ViewDeclarationLanguage getViewDeclarationLanguage(java.lang.String viewId)
```
    Return the ViewDeclarationLanguage instance suitable for handling the VDL contained in the page referenced by the argument viewId. The default implementation must return a valid ViewDeclarationLanguage instance for views written in either Jakarta Server Pages, Faces XML Views, or Facelets for Jakarta Server Faces 2.
    
    Parameters:
    
    viewId - the viewId to be inspected for an appropriate ViewDeclarationLanguage implementation for the VDL used in the view.
    
    Returns:
    
    the ViewDeclarationLanguage corresponding to the argument viewId
    
    Throws:
    
    java.lang.NullPointerException - if viewId is null.
