| template<typename OtherDeviceType , class = typename std::enable_if<!std::is_same<DeviceType, OtherDeviceType>::value>::type> | |
| TransformedBasisValues (const TransformedBasisValues< Scalar, OtherDeviceType > &transformedVectorData) | |
| copy-like constructor for differing device types. This may do a deep_copy of underlying views, depending on the memory spaces involved. | |
| TransformedBasisValues () | |
| Default constructor; an invalid container. Will return -1 for numCells(). | |
| KOKKOS_INLINE_FUNCTION bool | axisAligned () const |
| Returns true if the transformation matrix is diagonal. | |
| BasisValues< Scalar, DeviceType > | basisValues () const |
| KOKKOS_INLINE_FUNCTION int | cellDataExtent () const |
| Returns the true data extent in the cell dimension (e.g., will be 1 for transform matrices that do not vary from one cell to the next). | |
|
KOKKOS_INLINE_FUNCTION DataVariationType | cellVariationType () const |
| Returns the variation type corresponding to the cell dimension. | |
| template<class ViewType > | |
| void | multiplyByPointwiseWeights (const ViewType &weights) |
| Replaces the internal pullback (transformation operator) with the result of the pullback multiplied by the specified (C,P) weights. ViewType may be a rank-2 Kokkos::View, a rank-2 Kokkos::DynRankView, or a rank-2 Intrepid2::Data object. | |
| KOKKOS_INLINE_FUNCTION int | numCells () const |
| Returns the logical extent in the cell dimension, which is the 0 dimension in this container. | |
| KOKKOS_INLINE_FUNCTION int | numFields () const |
| Returns the logical extent in the fields dimension, which is the 1 dimension in this container. | |
| KOKKOS_INLINE_FUNCTION int | numPoints () const |
| Returns the logical extent in the points dimension, which is the 2 dimension in this container. | |
| KOKKOS_INLINE_FUNCTION int | spaceDim () const |
| Returns the logical extent in the space dimension, which is the 3 dimension in this container. | |
| KOKKOS_INLINE_FUNCTION Scalar | operator() (const int &cellOrdinal, const int &fieldOrdinal, const int &pointOrdinal) const |
| Scalar accessor, with arguments (C,F,P). | |
| KOKKOS_INLINE_FUNCTION Scalar | operator() (const int &cellOrdinal, const int &fieldOrdinal, const int &pointOrdinal, const int &dim) const |
| Vector accessor, with arguments (C,F,P,D). | |
| KOKKOS_INLINE_FUNCTION Scalar | transformWeight (const int &cellOrdinal, const int &pointOrdinal) const |
| Returns the specified entry in the (scalar) transform. (Only valid for scalar-valued BasisValues; see the four-argument transformWeight() for the vector-valued case.) | |
| KOKKOS_INLINE_FUNCTION Scalar | transformWeight (const int &cellOrdinal, const int &pointOrdinal, const int &dim1, const int &dim2) const |
| Returns the specified entry in the transform matrix. | |
| const Data< Scalar, DeviceType > & | transform () const |
| Returns the transform matrix. An invalid/empty container indicates the identity transform. | |
|
const VectorData< Scalar, DeviceType > & | vectorData () const |
| Returns the reference-space vector data. | |
| KOKKOS_INLINE_FUNCTION unsigned | rank () const |
| Returns the rank of the container, which is 3 for scalar values, and 4 for vector values. | |
| KOKKOS_INLINE_FUNCTION int | extent_int (const int &r) const |
| Returns the extent in the specified dimension as an int. | |
Public Attributes | |
| ordinal_type | numCells_ |
| Data< Scalar, DeviceType > | transform_ |
| BasisValues< Scalar, DeviceType > | basisValues_ |
Structure-preserving representation of transformed vector data; reference space values and transformations are stored separately.
TransformedBasisValues provides a View-like interface of rank 4, with shape (C,F,P,D). When the corresponding accessor is used, the transformed value is determined from corresponding reference space values and the transformation.
