## Detailed Description

template<typename InGridT, typename MaskGridType, typename OutGridT, typename MapT, typename OperatorT, typename InterruptT = util::NullInterrupter>
class openvdb::v11_0::tools::gridop::GridOperator< InGridT, MaskGridType, OutGridT, MapT, OperatorT, InterruptT >

Apply an operator to an input grid to produce an output grid with the same active voxel topology but a potentially different value type.

To facilitate inlining, this class is also templated on a Map type.

Note
  This is a helper class and should never be used directly.
