Superclass for all sources, filters, and sinks in VTK.
Definition: vtkAlgorithm.h:123
general representation of visualization data
abstract class to specify dataset behavior
Definition: vtkDataSet.h:166
a simple class to control print indentation
Definition: vtkIndent.h:113
Store zero or more vtkInformation instances.
Store vtkAlgorithm input/output information.
Superclass for algorithms that produce only Selection as output.
vtkSelection * GetOutput()
Get the output data object for a port on this algorithm.
vtkSelection * GetOutput(int index)
virtual int RequestUpdateExtent(vtkInformation *, vtkInformationVector **, vtkInformationVector *)
This is called by the superclass.
void SetInputData(vtkDataObject *obj)
Assign a data object as input.
int FillInputPortInformation(int port, vtkInformation *info) override
Fill the input port information objects for this algorithm.
~vtkSelectionAlgorithm() override
virtual int RequestData(vtkInformation *request, vtkInformationVector **inputVector, vtkInformationVector *outputVector)
This is called by the superclass.
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
int FillOutputPortInformation(int port, vtkInformation *info) override
Fill the output port information objects for this algorithm.
static vtkSelectionAlgorithm * New()
vtkTypeBool ProcessRequest(vtkInformation *, vtkInformationVector **, vtkInformationVector *) override
see vtkAlgorithm for details
void SetInputData(int index, vtkDataObject *obj)
virtual int RequestInformation(vtkInformation *request, vtkInformationVector **inputVector, vtkInformationVector *outputVector)
data object that represents a "selection" in VTK.
