      • EpollEvent

        public EpollEvent​(java.nio.ByteBuffer container)
        Creates a EpollEvent instance at the current position of the specified ByteBuffer container. Changes to the buffer's content will be visible to the struct instance and vice versa.

        The created instance holds a strong reference to the container object.
