  • Constructor Details

    • IOURingBuf

      public IOURingBuf(ByteBuffer container)
      Creates a IOURingBuf 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.

  • Method Details

      public short bid()
      Returns:
      the value of the bid field.

    • addr

      public IOURingBuf addr(long value)
      Sets the specified value to the addr field.

    • len

      public IOURingBuf len(int value)
      Sets the specified value to the len field.

    • bid

      public IOURingBuf bid(short value)
      Sets the specified value to the bid field.

    • set

      public IOURingBuf set(long addr, int len, short bid)
      Initializes this struct with the specified values.

    • set

      public IOURingBuf set(IOURingBuf src)
      Copies the specified struct data to this struct.
      Parameters:
      src - the source struct
      Returns:
      this struct

    • malloc

      public static IOURingBuf malloc()
