// .NAME vtkXMLPUnstructuredGridReader - Read PVTK XML UnstructuredGrid files.

|
// .SECTION Description
|
||
|
|
// vtkXMLPUnstructuredGridReader reads the PVTK XML UnstructuredGrid
|
||
|
|
// file format. This reads the parallel format's summary file and
|
||
|
|
// then uses vtkXMLUnstructuredGridReader to read data from the
|
||
|
|
// individual UnstructuredGrid piece files. Streaming is supported.
|
||
|
|
// The standard extension for this reader's file format is "pvtu".
