  • Method Details

    • checkNotNull

      static void checkNotNull(ByteBuffer[] buffers)
      Throws IllegalArgumentException if any of the buffers in the array are null.
    • remaining

      static long remaining(ByteBuffer[] buffers)
      Returns the total number of bytes remaining in the buffer array.
    • consume

      static void consume(ByteBuffer[] sourceBuffers, int toConsume)
      Marks toConsume bytes of data as consumed from the buffer array.
      Throws:
      IllegalArgumentException - if there are fewer than toConsume bytes remaining
    • getBufferLargerThan

      static ByteBuffer getBufferLargerThan(ByteBuffer[] buffers, int minSize)
      Looks for a buffer in the buffer array which EITHER is larger than minSize AND has no preceding non-empty buffers OR is the only non-empty buffer in the array.
    • copyNoConsume

      static ByteBuffer copyNoConsume(ByteBuffer[] buffers, ByteBuffer destination, int maxAmount)
      Copies up to maxAmount bytes from a buffer array to destination. The copied data is not marked as consumed from the source buffers, on the assumption the copy will be passed to some method which will consume between 0 and maxAmount bytes which can then be reflected in the source array using the consume() method.
