    • Method Detail

      • get

        T get()
        The contextual reference is obtained lazily, i.e. when first needed.
        Returns:
        the contextual reference
        Throws:
        IllegalStateException - If the producing WeldInstance does not exist
        See Also:
        Provider.get()

      • getBean

        javax.enterprise.inject.spi.Bean<?> getBean()
        Returns:
        the bean metadata

      • destroy

        void destroy()
        Destroy the contextual instance. It's a no-op if:
        • called multiple times
        • if the producing WeldInstance does not exist
        • if the handler does not hold a contextual reference, i.e. get() was never called
