## Member Function Documentation

void vtkPDataSetReader::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 vtkSource.

virtual const char* vtkPDataSetReader::GetClassName | ( |  | ) | `[virtual]`

| Reimplemented from vtkSource.

int vtkPDataSetReader::IsTypeOf | ( | const char * | type | ) | `[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 vtkTypeRevisionMacro found in vtkSetGet.h. Reimplemented from vtkSource.

virtual int vtkPDataSetReader::IsA | ( | const char * | type | ) | `[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 vtkTypeRevisionMacro found in vtkSetGet.h. Reimplemented from vtkSource.

vtkPDataSetReader* vtkPDataSetReader::SafeDownCast | ( | vtkObject * | o | ) | `[static]`

| Reimplemented from vtkSource.

vtkPDataSetReader* vtkPDataSetReader::New | ( |  | ) | `[static]`

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

virtual int vtkPDataSetReader::GetNumberOfOutputs | ( |  | ) | `[inline, virtual]`

| Let everyone know we have one output before the output is set. Reimplemented from vtkSource. Definition at line 55 of file vtkPDataSetReader.h.

virtual void vtkPDataSetReader::SetFileName | ( | const char * |  | ) | `[virtual]`

| This file to open and read.

virtual char* vtkPDataSetReader::GetFileName | ( |  | ) | `[virtual]`

| This file to open and read.

void vtkPDataSetReader::SetOutput | ( | vtkDataSet * | output | ) |

| The output of this reader depends on the file choosen. You cannot get the output until the filename is set.

virtual vtkDataSet* vtkPDataSetReader::GetOutput | ( |  | ) | `[virtual]`

| The output of this reader depends on the file choosen. You cannot get the output until the filename is set.

virtual vtkDataSet* vtkPDataSetReader::GetOutput | ( | int | idx | ) | `[virtual]`

| The output of this reader depends on the file choosen. You cannot get the output until the filename is set. Reimplemented from vtkSource.

virtual void vtkPDataSetReader::Update | ( |  | ) | `[virtual]`

| We need to define this so that the output gets created. Reimplemented from vtkSource.

virtual int vtkPDataSetReader::GetDataType | ( |  | ) | `[virtual]`

| This is set when UpdateInformation is called. It shows the type of the output.

virtual int vtkPDataSetReader::ReadOutputType | ( |  | ) | `[virtual]`

| This method can be used to find out the type of output expected without needing to read the whole file.

int vtkPDataSetReader::CanReadFile | ( | const char * | filename | ) |

| Called to determine if the file can be read by the reader.

virtual void vtkPDataSetReader::ExecuteInformation | ( |  | ) | `[protected, virtual]`

| Reimplemented from vtkSource.

void vtkPDataSetReader::ReadPVTKFileInformation | ( | ifstream * | fp | ) | `[protected]`

void vtkPDataSetReader::ReadVTKFileInformation | ( | ifstream * | fp | ) | `[protected]`

virtual void vtkPDataSetReader::Execute | ( |  | ) | `[protected, virtual]`

| This method is the old style execute method Reimplemented from vtkSource.

void vtkPDataSetReader::PolyDataExecute | ( |  | ) | `[protected]`

void vtkPDataSetReader::UnstructuredGridExecute | ( |  | ) | `[protected]`

void vtkPDataSetReader::ImageDataExecute | ( |  | ) | `[protected]`

void vtkPDataSetReader::StructuredGridExecute | ( |  | ) | `[protected]`

void vtkPDataSetReader::CoverExtent | ( | int | ext[6],
|  | int * | pieceMask
| ) | `[protected]`

vtkDataSet* vtkPDataSetReader::CheckOutput | ( |  | ) | `[protected]`

void vtkPDataSetReader::SetNumberOfPieces | ( | int | num | ) | `[protected]`

ifstream* vtkPDataSetReader::OpenFile | ( | const char * |  | ) | `[protected]`

int vtkPDataSetReader::ReadXML | ( | ifstream * | file,
|  | char ** | block,
|  | char ** | param,
|  | char ** | value
| ) | `[protected]`

void vtkPDataSetReader::SkipFieldData | ( | ifstream * | file | ) | `[protected]`
