staticconstexprprivate |
Compilation switch for the serial evaluation strategy of the map expression.
The useAssign compile time constant expression represents a compilation switch for the serial evaluation strategy of the map expression. In case either of the two dense vector operands requires an intermediate evaluation, useAssign will be set to true and the map expression will be evaluated via the assign function family. Otherwise useAssign will be set to false and the expression will be evaluated via the subscript operator.
