template<typename VT, typename ST, bool TF>
class blaze::DVecScalarDivExpr< VT, ST, TF >
Expression object for divisions of a dense vector by a scalar.
The DVecScalarDivExpr class represents the compile time expression for divisions of dense vectors by scalar values.
◆ anonymous enum
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.
◆ anonymous enum
template<typename VT, typename ST, bool TF>
Compilation switch for the serial evaluation strategy of the division expression.
The useAssign compile time constant expression represents a compilation switch for the serial evaluation strategy of the division 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 division 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.
