* Application represents a per-web-application singleton object where applications based on JavaServer Faces (or
* implementations wishing to provide extended functionality) can register application-wide singletons that provide
* functionality required by JavaServer Faces. Default implementations of each object are provided for cases where the
* application does not choose to customize the behavior.
*
*
*
* The instance of {@link Application} is created by calling the getApplication() method of
* {@link ApplicationFactory}. Because this instance is shared, it must be implemented in a thread-safe manner.
*
*
* Holds webapp-wide resources for a Faces application. There is a single one of these for a web application, accessable
* via
*
*
* FacesContext.getCurrentInstance().getApplication()
*
*
* In particular, this provides a factory for UIComponent objects. It also provides convenience methods for creating
* ValueBinding objects.
