Method Details

initView

public void initView(FacesContext context) throws FacesException

Deprecated.

Do not call the default implementation of ViewHandler.initView(jakarta.faces.context.FacesContext) if the ExternalContext.getRequestCharacterEncoding() returns a non-null result.

Overrides:

initView in class ViewHandler

Parameters:

context - the Faces context.

Throws:

FacesException - if a problem occurs setting the encoding, such as the UnsupportedEncodingException thrown by the underlying Jakarta Servlet or Portlet technology when the encoding is not supported.

See Also:

ViewHandler.initView(jakarta.faces.context.FacesContext)

renderView

public void renderView(FacesContext context, UIViewRoot viewToRender) throws IOException, FacesException

Deprecated.

Description copied from class: ViewHandler

Perform whatever actions are required to render the response view to the response object associated with the current FacesContext.

Otherwise, the default implementation must obtain a reference to the ViewDeclarationLanguage for the viewId of the argument viewToRender and call its ViewDeclarationLanguage.renderView(jakarta.faces.context.FacesContext, jakarta.faces.component.UIViewRoot) method, returning the result and not swallowing any exceptions thrown by that method.

Specified by:

renderView in class ViewHandler

Parameters:

context - FacesContext for the current request

viewToRender - the view to render

Throws:

IOException - if an input/output error occurs

FacesException - if a Jakarta Servlet error occurs

restoreView

public UIViewRoot restoreView(FacesContext context, String viewId)

Deprecated.

Description copied from class: ViewHandler

Perform whatever actions are required to restore the view associated with the specified FacesContext and viewId. It may delegate to the restoreView of the associated StateManager to do the actual work of restoring the view. If there is no available state for the specified viewId, return null.

Otherwise, the default implementation must obtain a reference to the ViewDeclarationLanguage for this viewId and call its ViewDeclarationLanguage.restoreView(jakarta.faces.context.FacesContext, java.lang.String) method, returning the result and not swallowing any exceptions thrown by that method.

Specified by:

restoreView in class ViewHandler

Parameters:

context - FacesContext for the current request

viewId - the view identifier for the current request

Returns:

the restored view root, or null.

createView

public UIViewRoot createView(FacesContext context, String viewId)

Deprecated.

Description copied from class: ViewHandler

Create and return a new UIViewRoot instance initialized with information from the argument FacesContext and viewId. Locate the ViewDeclarationLanguage implementation for the VDL used in the view. The argument viewId must be converted to a physical viewId that can refer to an actual resource suitable for use by the ViewDeclarationLanguage ViewDeclarationLanguage.createView(jakarta.faces.context.FacesContext, java.lang.String), which must be called by this method.

Specified by:

createView in class ViewHandler

Parameters:

context - the Faces context.

viewId - the view id.

Returns:

the viewroot.

calculateLocale

public Locale calculateLocale(FacesContext context)

Deprecated.

Description copied from class: ViewHandler

Returns an appropriate Locale to use for this and subsequent requests for the current client.

Specified by:

calculateLocale in class ViewHandler

Parameters:

context - FacesContext for the current request

Returns:

the locale.

calculateRenderKitId

public String calculateRenderKitId(FacesContext context)

Deprecated.

Description copied from class: ViewHandler

Return an appropriate renderKitId for this and subsequent requests from the current client. It is an error for this method to return null.

The default return value is RenderKitFactory.HTML_BASIC_RENDER_KIT.

Specified by:

calculateRenderKitId in class ViewHandler

Parameters:

context - FacesContext for the current request

Returns:

the render kit id.

findMatch

protected Locale findMatch(FacesContext context, Locale pref)

Deprecated.

Attempts to find a matching locale based on pref and list of supported locales, using the matching algorithm as described in JSTL 8.3.2.

Parameters:

context - the FacesContext for the current request

pref - the preferred locale

Returns:

the Locale based on pref and the matching alogritm specified in JSTL 8.3.2

writeState

public void writeState(FacesContext context) throws IOException

Deprecated.

Description copied from class: ViewHandler

Take any appropriate action to either immediately write out the current state information (by calling StateManager.writeState(jakarta.faces.context.FacesContext, java.lang.Object), or noting where state information should later be written.

This method must do nothing if the current request is an Ajax request. When responding to Ajax requests, the state is obtained by calling StateManager.getViewState(jakarta.faces.context.FacesContext) and then written into the Ajax response during final encoding (PartialViewContext.processPartial(jakarta.faces.event.PhaseId)) .

Specified by:

writeState in class ViewHandler

Parameters:

context - FacesContext for the current request

Throws:

IOException - if an input/output error occurs

getActionURL

public String getActionURL(FacesContext context, String viewId)

Deprecated.

Description copied from class: ViewHandler

If the value returned from this method is used as the file argument to the four-argument constructor for java.net.URL (assuming appropriate values are used for the first three arguments), then a client making a request to the toExternalForm() of that URL will select the argument viewId for traversing the Jakarta Server Faces lifecycle. Please see section 7.6.2 for the complete specification, especially for details related to view protection using the ResponseStateManager.NON_POSTBACK_VIEW_TOKEN_PARAM and the behavior when the current request is to a URL for which the FacesServlet has an exact mapping as defined by Servlet.12.2.

Specified by:

getActionURL in class ViewHandler

Parameters:

context - FacesContext for this request

viewId - View identifier of the desired view

Returns:

the action url.

getResourceURL

public String getResourceURL(FacesContext context, String path)

Deprecated.

Description copied from class: ViewHandler

If the value returned from this method is used as the file argument to the four-argument constructor for java.net.URL (assuming appropriate values are used for the first three arguments), then a client making a request to the toExternalForm() of that URL will select the argument path for direct rendering. If the specified path starts with a slash, it must be treated as context relative; otherwise, it must be treated as relative to the action URL of the current view.

Specified by:

getResourceURL in class ViewHandler

Parameters:

context - FacesContext for the current request

path - Resource path to convert to a URL

Returns:

the resource URL.

getWebsocketURL

public String getWebsocketURL(FacesContext context, String channel)

Deprecated.

Description copied from class: ViewHandler

If the value returned from this method is used as the file argument to the four-argument constructor for java.net.URL (assuming appropriate values are used for the first three arguments), then a client making a push handshake request to the toExternalForm() of that URL will select the argument channel for connecting the websocket push channel in the current view. It must match the PushContext.URI_PREFIX of the endpoint.

Specified by:

getWebsocketURL in class ViewHandler

Parameters:

context - FacesContext for the current request.

channel - The channel name of the websocket.

Returns:

the websocket URL.
