Detailed Description

template<typename, bool>
class blaze::SVecTransExpr< typename, bool >

Expression object for sparse vector transpositions.

The SVecTransExpr class represents the compile time expression for transpositions of sparse vectors.

Member Enumeration Documentation

template<typename , bool >
anonymous enum
private

Compilation switch for the evaluation strategy of the transposition expression.

The useAssign compile time constant expression represents a compilation switch for the 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.
