public abstract class NavigationHandlerWrapper extends NavigationHandler implements FacesWrapper<NavigationHandler>
NavigationHandlerWrapper provides a simple
implementation of NavigationHandler that can be subclassed by developers wishing to
provide specialized behavior to an existing NavigationHandler instance. The default
implementation of all methods is to call through to the wrapped NavigationHandler
instance.
Usage: extend this class and push the implementation being wrapped to the constructor and use
getWrapped() to access the instance being wrapped.

NavigationHandler
Perform 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 to
ConfigurableNavigationHandler.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 all invoking
PartialViewContext.setRenderAll(boolean)) if the view identifier has
changed as the result of an application action (to take into account
Ajax requests).

NavigationHandler
Overloaded 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 decorated NavigationHandler
implementations that conform to an earlier version of the specification, an implementation is
provided that calls through to
NavigationHandler.handleNavigation(javax.faces.context.FacesContext, java.lang.String, java.lang.String),
ignoring the toFlowDocumentId parameter.
