// .NAME vtkXMLPMultiBlockDataWriter - parallel writer for
// vtkHierarchicalBoxDataSet.
// .SECTION Description
// vtkXMLPCompositeDataWriter writes (in parallel or serially) the VTK XML
// multi-group, multi-block hierarchical and hierarchical box files. XML
// multi-group data files are meta-files that point to a list of serial VTK
// XML files.

// Controller used to communicate data type of blocks.

// If no controller is set, only the local blocks will be written
// to the meta-file.

// Description:
// Determine the data types for each of the leaf nodes.
// Currently each process requires this information in order to
// simplify creating the file names for both the metadata file
// as well as the actual dataset files. It takes into account
// that a piece of a dataset may be distributed in multiple pieces
// over multiple processes.

// the children of compositeData as well as write the actual data
// set files. element will only have added nested information.
// writerIdx is the global piece index used to create unique
// filenames for each file written. This function returns 0 if
// no files were written from compositeData. Process 0 creates
// the metadata for all of the processes/files.
virtual int WriteComposite(vtkCompositeDataSet* compositeData,

// Description:
// Internal method to write a non vtkCompositeDataSet subclass as
// well as add in the file name to the metadata file.
// Element is the containing XML metadata element that may
// have data overwritten and added to (the index XML attribute
// should not be touched though). writerIdx is the piece index
// that gets incremented for the globally numbered piece.
// If this piece exists on multiple processes than it also takes
// care of that in the metadata description. This function returns
// 0 if no file was written.

// the dataSetType.
