Detailed Description

Read VTK XML UnstructuredGrid files.

vtkXMLUnstructuredGridReader reads the VTK XML UnstructuredGrid file format. One unstructured grid file can be read to produce one output. Streaming is supported. The standard extension for this reader's file format is "vtu". This reader is also used to read a single piece of the parallel file format.

Member Function Documentation

virtual const char* vtkXMLUnstructuredGridReader::GetClassName ( )
virtual

Reimplemented from vtkXMLUnstructuredDataReader.

static int vtkXMLUnstructuredGridReader::IsTypeOf ( const char *  name)
static

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkXMLUnstructuredDataReader.

virtual int vtkXMLUnstructuredGridReader::IsA ( const char *  name)
virtual

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkXMLUnstructuredDataReader.

static vtkXMLUnstructuredGridReader* vtkXMLUnstructuredGridReader::SafeDownCast ( vtkObject o)
static

Reimplemented from vtkXMLUnstructuredDataReader.

void vtkXMLUnstructuredGridReader::PrintSelf ( ostream &  os,
vtkIndent  indent 
)
virtual

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkXMLUnstructuredDataReader.

static vtkXMLUnstructuredGridReader* vtkXMLUnstructuredGridReader::New ( )
static

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkAlgorithm.

vtkUnstructuredGrid* vtkXMLUnstructuredGridReader::GetOutput ( )

Get the reader's output.

vtkUnstructuredGrid* vtkXMLUnstructuredGridReader::GetOutput ( int  idx)

Get the reader's output.

const char* vtkXMLUnstructuredGridReader::GetDataSetName ( )
protectedvirtual

virtual vtkIdType vtkXMLUnstructuredGridReader::GetNumberOfCellsInPiece ( int  piece)
protectedvirtual
virtual int vtkXMLUnstructuredGridReader::FillOutputPortInformation ( int  port,
vtkInformation info 
)
protectedvirtual

Fill the output port information objects for this algorithm. This is invoked by the first call to GetOutputPortInformation for each port so subclasses can specify what they can handle.

Reimplemented from vtkAlgorithm.
