template<typename VT, bool TF>
class blaze::SVecTransExpr< VT, TF >
Expression object for sparse vector transpositions.
The SVecTransExpr class represents the compile time expression for transpositions of sparse vectors.
◆ anonymous enum
template<typename VT , bool TF>
Compilation switch for the serial evaluation strategy of the transposition expression.
The useAssign compile time constant expression represents a compilation switch for the serial evaluation strategy of the transposition expression. In case the given sparse vector expression of type VT requires an intermediate evaluation, useAssign will be set to 1 and the transposition expression will be evaluated via the assign function family. Otherwise useAssign will be set to 0 and the expression will be evaluated via the subscript operator.
◆ SVecTransExpr()
template<typename VT , bool TF>
Constructor for the SVecTransExpr class.
- Parameters
-
sv | The sparse vector operand of the transposition expression. |
◆ at()
template<typename VT , bool TF>
Checked access to the vector elements.
- Parameters
-
index | Access index. The index has to be in the range . |
- Returns
- The resulting value.
- Exceptions
-
std::out_of_range | Invalid vector access index. |
◆ begin()
template<typename VT , bool TF>
Returns an iterator to the first non-zero element of the sparse vector.
- Returns
- Iterator to the first non-zero element of the sparse vector.
◆ canAlias()
template<typename VT , bool TF>
template<typename T >
Returns whether the expression can alias with the given address alias.
- Parameters
-
alias | The alias to be checked. |
- Returns
- true in case the expression can alias, false otherwise.
◆ canSMPAssign()
template<typename VT , bool TF>
Returns whether the expression can be used in SMP assignments.
