If the node is a leaf, then the range is determined by scanning the range of scalar data in n cells in the dataset. The implication is that there are no direct lists of cell ids per leaf node, instead the cell ids are implicitly known. Construct the scalar tree from the dataset provided.
Checks build times and modified time from input and reconstructs the tree if necessary.
This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkObject . The value of this ivar may change each time the locator is built. For legacy compatibility. Do not use.
