- - ### Constructor Detail

    - #### ByteVector

          public ByteVector()

      Construct byte vector instance with default block size.

    - #### ByteVector

          public ByteVector(int capacity)

      Construct byte vector instance.
      Parameters:
        `capacity` - initial block size

    - #### ByteVector

          public ByteVector(byte[] a)

      Construct byte vector instance.
      Parameters:
        `a` - byte array to use TODO should n should be initialized to a.length to be consistent with CharVector behavior? [GA]

    - #### ByteVector

          public ByteVector(byte[] a,
                            int capacity)

      Construct byte vector instance.
      Parameters:
        `a` - byte array to use
        `capacity` - initial block size TODO should n should be initialized to a.length to be consistent with CharVector behavior? [GA]

  - ### Method Detail

    - #### getArray

          public byte[] getArray()

      Obtain byte vector array.
      Returns:
        byte array

    - #### length

          public int length()

      Obtain number of items in array.
      Returns:
        number of items

    - #### capacity

          public int capacity()

      Obtain capacity of array.
      Returns:
        current capacity of array

    - #### put

          public void put(int index,
                          byte val)

      Pet byte at index.
      Parameters:
        `index` - the index
        `val` - a byte

    - #### get

          public byte get(int index)

      Get byte at index.
      Parameters:
        `index` - the index
      Returns:
        a byte

    - #### alloc

          public int alloc(int size)

      This is to implement memory allocation in the array. Like malloc().
      Parameters:
        `size` - to allocate
      Returns:
        previous length

    - #### trimToSize

          public void trimToSize()

      Trim byte vector to current length.
