 package javax.faces.application;

 import java.util.Map;

Provides a simple implementation of ViewHandler that can be subclassed by developers wishing to provide specialized behavior to an existing ViewHandler instance. The default implementation of all methods is to call through to the wrapped ViewHandler.

Usage: extend this class and override getWrapped() to return the instance we are wrapping.

Since:
1.2
 
 public abstract class ViewHandlerWrapper extends ViewHandler implements FacesWrapper<ViewHandler> {


    

Returns:
the instance that we are wrapping.
  
 
     public abstract ViewHandler getWrapped();
 
 
     // ------------------------ Methods from javax.faces.application.ViewHandler
 

    
 
 
     public String calculateCharacterEncoding(FacesContext context) {
 
         return getWrapped().calculateCharacterEncoding(context);
 
     }
        
    

The default behavior of this method is to call ViewHandler.calculateLocale(javax.faces.context.FacesContext) on the wrapped ViewHandler object.

    public Locale calculateLocale(FacesContext context) {
        return getWrapped().calculateLocale(context);
    }


    
    @Override
    public String deriveViewId(FacesContext contextString input) {
        return getWrapped().deriveViewId(contextinput);
    }

    
    @Override
    public String deriveLogicalViewId(FacesContext contextString input) {
        return getWrapped().deriveLogicalViewId(contextinput);
    }
    
    
    public String calculateRenderKitId(FacesContext context) {
        return getWrapped().calculateRenderKitId(context);
    }


    
    public UIViewRoot createView(FacesContext contextString viewId) {
        return getWrapped().createView(contextviewId);
    }


    
    public String getActionURL(FacesContext contextString viewId) {
        return getWrapped().getActionURL(contextviewId);
    }


    
    @Override
    public String getRedirectURL(FacesContext context,
                                 String viewId,
                                 Map<String,List<String>> parameters,
                                 boolean includeViewParams) {
        return getWrapped().getRedirectURL(context,
                                           viewId,
                                           parameters,
                                           includeViewParams);
    }


    
    @Override
    public String getBookmarkableURL(FacesContext context,
                                     String viewId,
                                     Map<String,List<String>> parameters,
                                     boolean includeViewParams) {
        return getWrapped().getBookmarkableURL(context,
                                               viewId,
                                               parameters,
                                               includeViewParams);
    }


    
    public String getResourceURL(FacesContext contextString path) {
        return getWrapped().getResourceURL(contextpath);
    }

    

The default behavior of this method is to call ViewHandler.getViewDeclarationLanguage(javax.faces.context.FacesContext,java.lang.String) on the wrapped ViewHandler object.

Since:
2.0
    @Override
                                                              String viewId) {
        return getWrapped().getViewDeclarationLanguage(contextviewId);
        
    }
    
    
    
    

The default behavior of this method is to call ViewHandler.initView(javax.faces.context.FacesContext) on the wrapped ViewHandler object.

    public void initView(FacesContext contextthrows FacesException {
        
        getWrapped().initView(context);
    }
    
    
    public void renderView(FacesContext contextUIViewRoot viewToRender)
    throws IOExceptionFacesException {
        getWrapped().renderView(contextviewToRender);
    }


    
    public UIViewRoot restoreView(FacesContext contextString viewId) {
        return getWrapped().restoreView(contextviewId);
    }    

    

The default behavior of this method is to call ViewHandler.writeState(javax.faces.context.FacesContext) on the wrapped ViewHandler object.

    public void writeState(FacesContext contextthrows IOException {
    }
