In this case, we can't borrow a vec as mutable inside of fill_vec on line 20. In contrast, for the last two move_semantics, we aren't creating a new vec inside of the fill_vec function this time.

Nettet31. A problem of "value types" with external resources (like std::vector or std::string) is that copying them tends to be quite expensive, and copies are created implicitly in various contexts, so this tends to be a performance concern. C++0x's answer to this problem is move semantics, which is conceptionally based on the idea of resource ... director of agriculture biharNettet7. Copy elision will do the job just fine. Even a C++03 compiler will elide the temporary. In particular, NRVO (named return value optimization) will, for this code, MatrixXd foo () { MatrixXd huge_matrix (N,N); return huge_matrix; } MatrixXd A = foo (); construct huge_matrix right inside A.

QVector b = a; you are requesting a copy. As others have mentioned implicit sharing will not copy the data at this point, but it is basically a copy on write (if either a or b are changing the data).
