Class NavigationCaseWrapper

java.lang.Object

jakarta.faces.application.NavigationCase

jakarta.faces.application.NavigationCaseWrapper

All Implemented Interfaces:

FacesWrapper<NavigationCase>

public abstract class NavigationCaseWrapper
extends NavigationCase
implements FacesWrapper<NavigationCase>

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

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

Since:

2.2

Constructors

Constructor	Description
NavigationCaseWrapper()	Deprecated. Use the other constructor taking the implementation being wrapped.

Constructor Details

NavigationCaseWrapper

@Deprecated
public NavigationCaseWrapper()

Deprecated.

Use the other constructor taking the implementation being wrapped.

NavigationCaseWrapper

public NavigationCaseWrapper(NavigationCase wrapped)

If this navigation case 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.

Since:

2.3

Returns:

the bookmarkable URL.

Throws:

MalformedURLException - if the process of constructing the URL causes this exception to be thrown.

getCondition

public Boolean getCondition(FacesContext context)

Description copied from class: NavigationCase
