- - ### Constructor Detail

    - #### ByteBuffer

          public ByteBuffer(byte[] bytes)

      Creates instance of ByteBuffer already filled by bytes.
      Parameters:
        `bytes` -

    - #### ByteBuffer

          public ByteBuffer(int cacheSize)

      Creates instance of ByteBuffer with byte array of required length.
      Parameters:
        `cacheSize` - length of byte array

  - ### Method Detail

    - #### append

          public ByteBuffer append(byte c)

      Appends byte to array if there are unfilled positions in it. Otherwize creates next link in the chain, and appends the byte to it.
      Parameters:
        `c` -
      Returns:
        instance of ByteBuffer to which byte was appended.

    - #### append

          public ByteBuffer append(byte[] bs,
                          int off,
                          int len)

      Appends segment of a byte array to array if there are unfilled positions in it. Otherwize creates next link in the chain, and appends data to it.
      Parameters:
        `c` -
      Returns:
        instance of ByteBuffer to which byte array was appended.

    - #### getBytes

          public byte[] getBytes()

      Returns stored byte array.
      Returns:
        stored byte array

    - #### getByteAt

          public byte getByteAt(int index)

      Returns byte at index. No check is fulfilled to provide high speed.
      Parameters:
        `index` -
      Returns:

    - #### getUsedSize

          public int getUsedSize()

      Returns actual number of byte stored in this link.
      Returns:

    - #### getCacheSize

          public int getCacheSize()

      Returns capacity of this link.
      Returns:

      Returns:

    - #### getPrevious

          public ByteBuffer getPrevious()

      Returns the previous link in the chain.
      Returns:

    - #### getNext

          public ByteBuffer getNext()

      Returns the next link in the chain.
      Returns:

    - #### setNext

          public void setNext(ByteBuffer b)

      Sets the next link in the chain.
      Parameters:
