Interface InjectionProvider

All Known Implementing Classes:

public interface InjectionProvider

This interface defines an integration point for Jakarta EE vendors. Each vendor will need to provide an implementation of this interface which will provide the Faces 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.
