|
ScalarView< PointScalar, DeviceType > | allocateAndFillExpandedRawPointView () const |
| This method is for compatibility with existing methods that take raw point views. Note that in general it is probably better for performance to make the existing methods accept a TensorPoints object, since that can dramatically reduce memory footprint, and avoids an allocation here. | |
| KOKKOS_INLINE_FUNCTION ScalarView< PointScalar, DeviceType > | getTensorComponent (const ordinal_type &r) const |
| Returns the requested tensor component. More... | |
| KOKKOS_INLINE_FUNCTION bool | isValid () const |
| Returns true for containers that have data; false for those that don't (e.g., those that have been constructed by the default constructor). | |
| KOKKOS_INLINE_FUNCTION ordinal_type | numTensorComponents () const |
| Returns the number of tensorial components. | |
|
KOKKOS_INLINE_FUNCTION constexpr ordinal_type | rank () const |
| Return the rank of the container, which is 2. | |
