  • Field Details

    • SIZEOF

      public static final int SIZEOF
      The struct size in bytes.
    • ALIGNOF

      public static final int ALIGNOF
      The struct alignment in bytes.
    • EVENTS

      public static final int EVENTS
      The struct member offsets.

  • Constructor Details

    • EpollEvent

      public EpollEvent(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.
