Detailed Description

template<class DeviceType>
class Intrepid2::OrientationOperator< DeviceType >

OrientationOperator.

Introduced in 2025, OrientationOperator seeks to make the application of orientations to vectors of local basis coefficients more efficient. Each orientation operator corresponds to a subcell (face or edge) of a basis, and applies the specified orientation map to the part of the basis corresponding to the subcell. The assumption is that the input and output vectors supplied prior to application of any orientation operators are identical, allowing the identity map to be implemented as a no-op.

The operator object is stored in a Kokkos::View and copied between host and device. To keep that safe for non-UVM CUDA builds, it deliberately stores only raw device pointers plus extents, rather than nested Kokkos::View handles.
