/**
 * @class   vtkArrayDataWriter
 * @brief   Serialize vtkArrayData to a file or stream.
 *
 *
 * vtkArrayDataWriter serializes vtkArrayData using a text-based
 * format that is human-readable and easily parsed (default option).  The
 * WriteBinary array option can be used to serialize the vtkArrayData
 * using a binary format that is optimized for rapid throughput.
 *
 * vtkArrayDataWriter can be used in two distinct ways: first, it can be used as a
 * normal pipeline filter, which writes its inputs to a file.  Alternatively, static
 * methods are provided for writing vtkArrayData instances to files or arbitrary c++
 * streams.
 *
 * Inputs:
 *   Input port 0: (required) vtkArrayData object.
 *
 * Output Format:
 *   See http://www.kitware.com/InfovisWiki/index.php/N-Way_Array_File_Formats for
 *   details on how vtkArrayDataWriter encodes data.
 *
 * @sa
