Class NavigationCaseWrapper

java.lang.Object

javax.faces.application.NavigationCase

javax.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

Method Details

getWrapped

public NavigationCase getWrapped()

Description copied from interface: FacesWrapper

A class that implements this interface uses this method to return an instance of the class being wrapped.

Overrides:

getActionURL in class NavigationCase

Parameters:

context - the FacesContext for the current request

Returns:

the action URL.

Throws:

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

getBookmarkableURL

public URL getBookmarkableURL(FacesContext context)
                       throws MalformedURLException

Description copied from class: NavigationCase

Construct an absolute URL suitable for a bookmarkable link to this NavigationCase instance using ViewHandler.getBookmarkableURL(javax.faces.context.FacesContext, java.lang.String, java.util.Map<java.lang.String, java.util.List<java.lang.String>>, boolean) on the path portion of the url.

Overrides:

getBookmarkableURL in class NavigationCase

Parameters:

context - the FacesContext for the current request

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

Evaluates the <if> for this <navigation-case>, if any. The expression to be evaluated is passed into the constructor as a string. When the expression is evaluated, its value must be coerced into a boolean per the normal EL coercion rules.

Note throws any exceptions encountered during the process of evaluating the expression or obtaining its value.

Overrides:

getCondition in class NavigationCase

Parameters:

context - the FacesContext for the current request

Returns:

null if there is no <if> element associated with this <navigation-case>, otherwise return the evaluation result of the condition
