- All Implemented Interfaces:
- FacesWrapper<NavigationHandler>
public abstract class NavigationHandlerWrapper extends NavigationHandler implements FacesWrapper<NavigationHandler>
NavigationHandlerWrapper provides a simple implementation of
NavigationHandlerthat can be subclassed by developers wishing to provide specialized behavior to an existingNavigationHandlerinstance. The default implementation of all methods is to call through to the wrappedNavigationHandlerinstance.getWrapped()to return the instance being wrapping.- Since:

getWrapped
public abstract NavigationHandler getWrapped()
Description copied from interface:FacesWrapperA class that implements this interface uses this method to return an instance of the class being wrapped.
- Specified by:
getWrappedin interfaceFacesWrapper<NavigationHandler>

handleNavigation
public void handleNavigation(FacesContext context, String fromAction, String outcome)
Description copied from class:NavigationHandlerPerform navigation processing based on the state information in the specified
FacesContext, plus the outcome string returned by an executed application action.If the implementation class also extends
ConfigurableNavigationHandler, the implementation must guarantee that the logic used in a call toConfigurableNavigationHandler.getNavigationCase(javax.faces.context.FacesContext, java.lang.String, java.lang.String)is used in this method to determine the correct navigation.This method must set the render targets (used in partial rendering) to
render allinvokingPartialViewContext.setRenderAll(boolean)) if the view identifier has changed as the result of an application action (to take into accountAjax requests).- Specified by:
handleNavigationin classNavigationHandler- Parameters:
context- TheFacesContextfor the current requestfromAction- The action binding expression that was evaluated to retrieve the specified outcome, ornullif the outcome was acquired by some other meansoutcome- The logical outcome returned by a previous invoked application action (which may benull)

handleNavigation
public void handleNavigation(FacesContext context, String fromAction, String outcome, String toFlowDocumentId)
Description copied from class:NavigationHandlerOverloaded variant of
NavigationHandler.handleNavigation(javax.faces.context.FacesContext, java.lang.String, java.lang.String)that allows the caller to provide the defining document id for a flow to be entered by this navigation. For backward compatibility with decoratedNavigationHandlerimplementations that conform to an earlier version of the specification, an implementation is provided that calls through toNavigationHandler.handleNavigation(javax.faces.context.FacesContext, java.lang.String, java.lang.String), ignoring thetoFlowDocumentIdparameter.- Overrides:
handleNavigationin classNavigationHandler- Parameters:
context- TheFacesContextfor the current requestfromAction- The action binding expression that was evaluated to retrieve the specified outcome, ornullif the outcome was acquired by some other meansoutcome- The logical outcome returned by a previous invoked application action (which may benull)toFlowDocumentId- The defining document id of the flow into which this navigation will cause entry.
