Method Detail

• isRichFacesInstalled

  public static boolean isRichFacesInstalled()

  Returns true if RichFaces is installed. That is, when the RichFaces specific ExtendedPartialViewContextImpl is present in the runtime classpath -which is present in RF 4.x. As this is usually auto-registered, we may safely assume that RichFaces is installed.

  Returns:

  Whether RichFaces is installed.

• getRichFacesPartialViewContext

  public static PartialViewContext getRichFacesPartialViewContext()

  RichFaces PartialViewContext implementation does not extend from PartialViewContextWrapper. So a hack wherin the exact fully qualified class name needs to be known has to be used to properly extract it from the FacesContext.getPartialViewContext().

  Returns:

  The RichFaces PartialViewContext implementation.

• getRichFacesRenderIds

  public static Collection<String> getRichFacesRenderIds()

  RichFaces PartialViewContext implementation does not have the getRenderIds() method properly implemented. So a hack wherin the exact name of the private field needs to be known has to be used to properly extract it from the RichFaces PartialViewContext implementation.

  Returns:

  The render IDs from the RichFaces PartialViewContext implementation.

• getRichFacesWrappedPartialViewContext

  public static PartialViewContext getRichFacesWrappedPartialViewContext()

  RichFaces PartialViewContext implementation does not have any getWrapped() method to return the wrapped PartialViewContext. So a reflection hack is necessary to return it from the private field.

  Returns:

  The wrapped PartialViewContext from the RichFaces PartialViewContext implementation.

• isRichFacesResourceOptimizationEnabled

  public static boolean isRichFacesResourceOptimizationEnabled()

  RichFaces "resource optimization" do not support Resource.getURL() and Resource.getInputStream(). The combined resource handler has to manually create the URL based on Resource.getRequestPath() and the current request domain URL whenever RichFaces "resource optimization" is enabled.

  Returns:

  Whether RichFaces resource optimization is enabled.

• isRichFacesResourceLibraryRenderer

  public static boolean isRichFacesResourceLibraryRenderer(String rendererType)

  Returns true if the given renderer type is recognizeable as RichFaces resource library renderer.

  Parameters:

  rendererType - The renderer type to be checked.

  Returns:

  Whether the given renderer type is recognizeable as RichFaces resource library renderer.

• getRichFacesResourceLibraryResources

  public static Set<ResourceIdentifier> getRichFacesResourceLibraryResources(ResourceIdentifier id)

  Returns an ordered set of all JSF resource identifiers for the given RichFaces resource library resources.

  Parameters:

  id - The resource identifier of the RichFaces resource library (e.g. org.richfaces:ajax.reslib).

  Returns:

  An ordered set of all JSF resource identifiers for the given RichFaces resource library resources.

• isJUELUsed

  public static boolean isJUELUsed()

• isJUELUsed

  public static boolean isJUELUsed(ExpressionFactory factory)

• isJUELSupportingMethodExpression

  public static boolean isJUELSupportingMethodExpression()

• methodExpressionToStaticMethod

  public static Method methodExpressionToStaticMethod(ELContext context,
                                      MethodExpression methodExpression)

  This method wraps a MethodExpression in a Method which can be statically invoked.

  Since Method is a final class with only a non-public constructor, various reflective tricks have been used to create an instance of this class and make sure it calls the given method expression. It has been tested on the Sun/Oracle JDK versions 6 and 7, and it should work on OpenJDK 6 and 7 as well. Other JDKs might not work.

  Parameters:

  context - the context used for evaluation of the method expression when it's invoked later. NOTE, this reference is retained by the returned method.

  methodExpression - the method expression to be wrapped

  Returns:

  a Method instance that when invoked causes the wrapped method expression to be invoked.

• isMyFacesUsed

  public static boolean isMyFacesUsed()

  Returns true if MyFaces is used. That is, when the FacesContext instance is from the MyFaces specific package.

  Returns:

  Whether MyFaces is used.

  Since:

  1.8

• setScriptResourceRendered

  public static void setScriptResourceRendered(FacesContext context,
                               ResourceIdentifier id)

  Set the given script resource as rendered.

  Parameters:

  context - The involved faces context.

  id - The resource identifier.

  Since:

  1.8

• setStylesheetResourceRendered

  public static void setStylesheetResourceRendered(FacesContext context,
                                   ResourceIdentifier id)

  Set the given stylesheet resource as rendered.

  Parameters:

  context - The involved faces context.

  id - The resource identifier.

  Since:

  1.8

• removeResourceDependencyState

  public static void removeResourceDependencyState(FacesContext context)

  Remove the resource dependency processing related attributes from the given faces context.

  Parameters:

  context - The involved faces context.

• isPrimeFacesDynamicResourceRequest

  public static boolean isPrimeFacesDynamicResourceRequest(FacesContext context)

  Returns true if the current request is a PrimeFaces dynamic resource request.

  Parameters:

  context - The involved faces context.

  Returns:

  Whether the current request is a PrimeFaces dynamic resource request.

  Since:

  1.8
