### write

    public void write(DataOutput out)
               throws IOException

  Serialize the fields of this object to `out`.

  Specified by:
    `write` in interface `Writable`
  Parameters:
    `out` - `DataOuput` to serialize this object into.
  Throws:
    `IOException`

### readFields

    public void readFields(DataInput in)
                    throws IOException

  For efficiency, implementations should attempt to re-use storage in the existing object where possible.

  Specified by:
    `readFields` in interface `Writable`
  Parameters:
    `in` - `DataInput` to deseriablize this object from.
  Throws:
    `IOException`

### getHeader

    public static String getHeader(boolean qOption)

  Return the header of the output. if qOption is false, output directory count, file count, and content size; if qOption is true, output quota and remaining quota as well.

  Parameters:
    `qOption` - a flag indicating if quota needs to be printed or not
  Returns:
    the header of the output

### toString

    public String toString()

  Overrides:
    `toString` in class `Object`

### toString

    public String toString(boolean qOption)

  Return the string representation of the object in the output format. if qOption is false, output directory count, file count, and content size; if qOption is true, output quota and remaining quota as well.

  Parameters:
    `qOption` - a flag indicating if quota needs to be printed or not
