    - #### GrowableByteArrayDataOutput

          public GrowableByteArrayDataOutput(int cp)

      Create a `GrowableByteArrayDataOutput` with the given initial capacity.

  - ### Method Detail

    - #### writeByte

          public void writeByte(byte b)

      Description copied from class: `DataOutput`
      Writes a single byte.

      The most primitive data type is an eight-bit byte. Files are accessed as sequences of bytes. All other data types are defined as sequences of bytes, so file formats are byte-order independent.

      Specified by:
        `writeByte` in class `DataOutput`
      See Also:
        `DataInput.readByte()`

    - #### writeBytes

          public void writeBytes(byte[] b,
                                 int off,
                                 int len)

      Description copied from class: `DataOutput`
      Writes an array of bytes.
      Specified by:
        `writeBytes` in class `DataOutput`
      Parameters:
        `b` - the bytes to write
        `off` - the offset in the byte array
        `len` - the number of bytes to write
      See Also:
        `DataInput.readBytes(byte[],int,int)`

    - #### writeString

          public void writeString(String string)
                           throws IOException

      Description copied from class: `DataOutput`
      Writes a string.

      Writes strings as UTF-8 encoded bytes. First the length, in bytes, is written as a `VInt`, followed by the bytes.

      Overrides:
        `writeString` in class `DataOutput`
      Throws:
        `IOException`
      See Also:
        `DataInput.readString()`

    - #### getBytes

          public byte[] getBytes()

    - #### getPosition

          public int getPosition()

    - #### reset

          public void reset()
