Class BufferByteArray

    • Field Detail

      • bb

        protected IoBuffer bb
        The backing IoBuffer.

    • Constructor Detail

      • BufferByteArray

        public BufferByteArray​(IoBuffer bb)
        Creates a new instance of BufferByteArray and uses the supplied IoBuffer to back this class
        Parameters:
        bb - The backing buffer

    • Method Detail

      • getIoBuffers

        public Iterable<IoBuffer> getIoBuffers()
        Returns:
        the sequence of IoBuffers that back this array. Compared to getSingleIoBuffer(), this method should be relatively efficient for all implementations.

      • getSingleIoBuffer

        public IoBuffer getSingleIoBuffer()
        Returns:
        a single IoBuffer that backs this array. Some implementations may initially have data split across multiple buffers, so calling this method may require a new buffer to be allocated and populated.

      • slice

        public ByteArray slice​(int index,
                       int length)
        Creates an array with a view of part of this array. Calling free() on the returned slice has no effect.
        Parameters:
        index - The starting position
        length - The number of bytes to copy
        Returns:
        The ByteArray that is a view on the original array

      • cursor

        public ByteArray.Cursor cursor()
        Returns:
        a cursor starting at index 0 (which may not be the start of the array).

      • cursor

        public ByteArray.Cursor cursor​(int index)
        Parameters:
        index - The starting point
        Returns:
        a cursor starting at the given index.

      • first

        public int first()
        Returns:
        the index of the first byte that can be accessed.

      • last

        public int last()
        Returns:
        the index after the last byte that can be accessed.

      • order

        public ByteOrder order()
        Returns:
        the order of the bytes.

      • order

        public void order​(ByteOrder order)
        Set the byte order of the array.
        Parameters:
        order - The ByteOrder to use

        a byte from the given index.

      • put

        public void put​(int index,
                byte b)
        Puts a byte at the given index.
        Parameters:
        index - The position
        b - The byte to put

      • get

      • put

        public void put​(int index,
