abstract class to specify dataset behavior
Definition: vtkDataSet.h:53
subset a vtkDataSet to create a vtkUnstructuredGrid
void SetCellIds(const vtkIdType *ptr, vtkIdType numValues)
Another way to provide ids using a pointer to vtkIdType array.
void SetCellList(vtkIdList *l)
Set the list of cell IDs that the output vtkUnstructuredGrid will be composed of.
~vtkExtractCells() override
void PrintSelf(ostream &os, vtkIndent indent) override
Standard methods for construction, type info, and printing.
vtkSmartPointer< vtkExtractCellsIdList > CellList
void AddCellList(vtkIdList *l)
Add the supplied list of cell IDs to those that will be included in the output vtkUnstructuredGrid.
int RequestData(vtkInformation *, vtkInformationVector **, vtkInformationVector *) override
This is called by the superclass.
void AddCellIds(const vtkIdType *ptr, vtkIdType numValues)
Another way to provide ids using a pointer to vtkIdType array.
static vtkExtractCells * New()
Standard methods for construction, type info, and printing.
void AddCellRange(vtkIdType from, vtkIdType to)
Add this range of cell IDs to those that will be included in the output vtkUnstructuredGrid.
bool Copy(vtkDataSet *input, vtkUnstructuredGrid *output)
int FillInputPortInformation(int port, vtkInformation *info) override
Fill the input port information objects for this algorithm.
list of point or cell ids
Definition: vtkIdList.h:23
a simple class to control print indentation
Definition: vtkIndent.h:29
Store zero or more vtkInformation instances.
Store vtkAlgorithm input/output information.
Superclass for algorithms that produce only unstructured grid as output.
dataset represents arbitrary combinations of all possible cell types
