class blaze::DVecAbsExpr< VT, TF >
Expression object for the dense vector abs() function.
The DVecAbsExpr class represents the compile time expression for the calculation of the absolute value of each element of a dense vector via the abs() function.
template<typename VT , bool TF>
Compilation switch for the selection of the subscript operator return type.
The returnExpr compile time constant expression is a compilation switch for the selection of the ReturnType. If the vector operand returns a temporary vector or matrix, returnExpr will be set to false and the subscript operator will return it's result by value. Otherwise returnExpr will be set to true and the subscript operator may return it's result as an expression.
template<typename VT , bool TF>
Compilation switch for the evaluation strategy of the absolute value expression.
The useAssign compile time constant expression represents a compilation switch for the evaluation strategy of the absolute value expression. In case the given dense vector expression of type VT requires an intermediate evaluation, useAssign will be set to 1 and the absolute value 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.
template<typename VT , bool TF>
Constructor for the DVecAbsExpr class.
- Parameters
-
dv | The dense vector operand of the absolute value expression. |
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.
template<typename VT , bool TF>
template<typename T >
Returns whether the expression is aliased with the given address alias.
- Parameters
-
alias | The alias to be checked. |
- Returns
- true in case an alias effect is detected, false otherwise.
template<typename VT , bool TF>
Returns the dense vector operand.
- Returns
- The dense vector operand.
template<typename VT , bool TF>
Subscript operator for the direct access to the vector elements.
- Parameters

template<typename , bool >
Conversion operator for non-constant vectors.
- Returns
- Reference of the actual type of the vector.
template<typename , bool >
Conversion operator for constant vectors.
