Detailed Description

Manages reading pieces of a data set.

vtkPDataSetReader will read a piece of a file, it takes as input a metadata file that lists all of the files in a data set.

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 vtkDataSetAlgorithm.

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

Reimplemented from vtkDataSetAlgorithm.

static int vtkPDataSetReader::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 vtkDataSetAlgorithm.

virtual int vtkPDataSetReader::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 vtkDataSetAlgorithm.

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

Reimplemented from vtkDataSetAlgorithm.

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

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

Reimplemented from vtkDataSetAlgorithm.

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

This file to open and read.

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

This file to open and read.

virtual int vtkPDataSetReader::GetDataType ( ) [virtual]

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

int vtkPDataSetReader::CanReadFile ( const char * filename )

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

virtual int vtkPDataSetReader::RequestDataObject	(	vtkInformation *	request,
		vtkInformationVector **	inputVector,
		vtkInformationVector *	outputVector
	)			`[protected, virtual]`

This is called within ProcessRequest to when a request asks the algorithm to create empty output data objects. This typically happens early on in the execution of the pipeline. The default behavior is to create an output DataSet of the same type as the input for each output port. This method can be overridden to change the output data type of an algorithm. This happens in the third pass of the pipeline execution.

Reimplemented from vtkDataSetAlgorithm.

void vtkPDataSetReader::ReadPVTKFileInformation	(	ifstream *	fp,
		vtkInformation *	request,
		vtkInformationVector **	inputVector,
		vtkInformationVector *	outputVector
	)			`[protected]`

void vtkPDataSetReader::ReadVTKFileInformation	(	ifstream *	fp,
		vtkInformation *	request,
		vtkInformationVector **	inputVector,
		vtkInformationVector *	outputVector
	)			`[protected]`

virtual int vtkPDataSetReader::RequestData	(	vtkInformation *	,
		vtkInformationVector **	,
		vtkInformationVector *
	)			`[protected, virtual]`

This is called within ProcessRequest when a request asks the algorithm to do its work. This is the method you should override to do whatever the algorithm is designed to do. This happens during the fourth pass in the pipeline execution process.

Reimplemented from vtkDataSetAlgorithm.
