Detailed Description

template<typename VT, bool TF>
class blaze::DVecTransExpr< VT, TF >

Expression object for dense vector transpositions.

The DVecTransExpr class represents the compile time expression for transpositions of dense vectors.

Member Enumeration Documentation

◆ anonymous enum

template<typename VT, bool TF>
anonymous enum : bool
private

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 dense 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.
