* @class vtkXMLMultiBlockDataReader
|
|
* @brief Reader for multi-block datasets
|
|
*
|
|
* vtkXMLMultiBlockDataReader reads the VTK XML multi-block data file
|
|
* format. XML multi-block data files are meta-files that point to a list
|
|
* of serial VTK XML files. When reading in parallel, it will distribute
|
|
* sub-blocks among processor. If the number of sub-blocks is less than
|
|
* the number of processors, some processors will not have any sub-blocks
|
|
* for that block. If the number of sub-blocks is larger than the
|
|
* number of processors, each processor will possibly have more than
|
|
* 1 sub-block.
