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 vtkObjectBase.

Sets the vtkSelectionNode used by this selection operator and initializes the data structures in the selection operator based on the selection.
(for example in the vtkFrustumSelector this creates the vtkPlanes implicit function to represent the frustum).

Reimplemented from vtkObject.
void vtkFrustumSelector::SetFrustum | ( | vtkPlanes * | ) |
Set the selection frustum.
The planes object must contain six planes.
vtkPlanes * vtkFrustumSelector::GetFrustum | ( | ) |
Set the selection frustum.
The planes object must contain six planes.

This method computes whether or not each element in the dataset is inside the selection and populates the given array with 0 (outside the selection) or 1 (inside the selection).
The vtkDataObject passed in will never be a vtkCompositeDataSet
subclass.
What type of elements are operated over is determined by the vtkSelectionNode's field association. The insidednessArray passed in should have the correct number of elements for that field type or it will be resized.
Returns true for successful completion. The operator should only return false when it cannot operate on the inputs. In which case, it is assumed that the insidednessArray may have been left untouched by this method and the calling code will fill it with 0.
Implements vtkSelector.
