vtkExtractSelectionBase

Section: Visualization Toolkit Graphics Classes

# Usage

vtkExtractSelectionBase is an abstract base class for all extract selection filters. It defines some properties common to all extract selection filters.

To create an instance of class vtkExtractSelectionBase, simply invoke its constructor as follows

      obj = vtkExtractSelectionBase

# Methods

The class vtkExtractSelectionBase has several methods that can be used. They are listed below. Note that the documentation is translated automatically from the VTK sources, and may not be completely intelligible. When in doubt, consult the VTK website. In the methods listed below, `obj` is an instance of the vtkExtractSelectionBase class.

- `string = obj.GetClassName ()`
- `int = obj.IsA (string name)`
- `vtkExtractSelectionBase = obj.NewInstance ()`
- `vtkExtractSelectionBase = obj.SafeDownCast (vtkObject o)`
- `obj.SetSelectionConnection (vtkAlgorithmOutput algOutput)` - This flag tells the extraction filter not to convert the selected output into an unstructured grid, but instead to produce a vtkInsidedness array and add it to the input dataset. Default value is false(0).
- `obj.SetPreserveTopology (int )` - This flag tells the extraction filter not to convert the selected output into an unstructured grid, but instead to produce a vtkInsidedness array and add it to the input dataset. Default value is false(0).
- `int = obj.GetPreserveTopology ()` - This flag tells the extraction filter not to convert the selected output into an unstructured grid, but instead to produce a vtkInsidedness array and add it to the input dataset. Default value is false(0).
- `obj.PreserveTopologyOn ()` - This flag tells the extraction filter not to convert the selected output into an unstructured grid, but instead to produce a vtkInsidedness array and add it to the input dataset. Default value is false(0).
- `obj.PreserveTopologyOff ()` - This flag tells the extraction filter not to convert the selected output into an unstructured grid, but instead to produce a vtkInsidedness array and add it to the input dataset. Default value is false(0).
