Definition at line 35 of file vtkSelector.h.
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 should be a non-composite data object.
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. The last three parameters give the data object's composite index, AMR level or AMR index.
Returns true for successful completion. The operator should only return false when it cannot operate on the inputs.
Implemented in vtkFrustumSelector, vtkValueSelector, vtkLocationSelector, and vtkBlockSelector.
