Detailed Description

produces simple (composite or atomic) data sets for testing.

vtkDataObjectGenerator parses a string and produces dataobjects from the dataobject template names it sees in the string. For example, if the string contains "ID1" the generator will create a vtkImageData. "UF1", "RD1", "SD1", "PD1", and "UG1" will produce vtkUniformGrid, vtkRectilinearGrid, vtkStructuredGrid, vtkPolyData and vtkUnstructuredGrid respectively. You can compose composite datasets from the atomic ones listed above by putting them between "(" and ")" in the string to create groups, and then placing a collection of groups together inside one of the three composite dataset identifiers - "MB{}", "HD<>" or "HB[]". "HB[ (UF1)(UF1)(UF1) ]" will create a vtkHierarchicalBoxDataSet representing an octree, in which the firstmost cell is refined, and then the firstmost refined cell is refined itself. "HD< (UG1UG1UG1) (PD1)>" will create a vtkHierachicalDataSet which contains two refinement levels, the first is a group with three unstructured grids, the second, more refined level is a vtkPolyData. "MB{ (ID1)(PD1 RG1)(MB{}) }" will create a vtkMultiBlockDataSet consisting of three groups. The first group has one data set, a vtkImageData. The second group has two datasets, a vtkPolyData and a vtkRectilinearGrid. The third contains a vtkMultiBlockDataSet, which in this case is empty.

Member Function Documentation

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

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

Reimplemented from vtkDataObjectAlgorithm.

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

Reimplemented from vtkDataObjectAlgorithm.

static int vtkDataObjectGenerator::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 vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkDataObjectAlgorithm.

virtual int vtkDataObjectGenerator::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 vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkDataObjectAlgorithm.

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

Reimplemented from vtkDataObjectAlgorithm.

void vtkDataObjectGenerator::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 vtkDataObjectAlgorithm.

virtual void vtkDataObjectGenerator::SetProgram ( const char * ) [virtual]

The string that will be parsed to specify a dataobject structure.

virtual char* vtkDataObjectGenerator::GetProgram ( ) [virtual]

The string that will be parsed to specify a dataobject structure.

virtual int vtkDataObjectGenerator::RequestData	(	vtkInformation *	req,
		vtkInformationVector **	inV,
		vtkInformationVector *	outV
	)			`[protected, virtual]`

Reimplemented from vtkDataObjectAlgorithm.

virtual int vtkDataObjectGenerator::RequestDataObject	(	vtkInformation *	,
		vtkInformationVector **	,
		vtkInformationVector *
	)			`[protected, virtual]`

This is called by the superclass. This is the method you should override.

Reimplemented from vtkDataObjectAlgorithm.

virtual int vtkDataObjectGenerator::RequestInformation	(	vtkInformation *	req,
		vtkInformationVector **	inV,
		vtkInformationVector *	outV
	)			`[protected, virtual]`
