class blaze::DVecScalarMultExpr< VT, ST, TF >
Expression object for dense vector-scalar multiplications.
The DVecScalarMultExpr class represents the compile time expression for multiplications between a dense vector and a scalar value.
template<typename VT, typename ST, 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, typename ST, bool TF>
Compilation switch for the serial evaluation strategy of the multiplication expression.
The useAssign compile time constant expression represents a compilation switch for the serial evaluation strategy of the multiplication expression. In case the given dense vector expression of type VT is a computation expression and requires an intermediate evaluation, useAssign will be set to 1 and the multiplication 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.
