Examples of com.sun.faces.spi.InjectionProvider

com.sun.faces.spi.InjectionProvider

This interface defines an integration point for Java EE vendors. Each vendor will need to provide an implementation of this interface which will provide the JSF implementation the necessary hooks to perform resource injection.

The implementation of this interface *must* be thread-safe and must provider either a no-arg constructor, or a constructor accepting a ServletContext instance.
