city map vector

Summarize my experience and lessons in the work. You can use the list, set, or map traversal to remove certain elements: Correct use of Method 1 Copy Code code as follows: std::liststd::listfor (itlist = List.begin (); itlist!= list.end ();) { if (Willdelete (*itlist)) { Itlist = List.erase (itlist); } Else itlist++; } correct use of Method 2 Copy Code code as follows: std::liststd::listfor (itl

Sequential containers::(vectors and lists and deque)The erase iterator not only invalidates all iterators that point to the deleted element, but also invalidates all iterators after the deleted element, so erase (iter++) cannot be used, but the return value of erase is the next valid iterator, so the correct method is:: For (iter = C.begin (); ITER! = C.end ();)iter = C.erase (ITER);Associative containers::(map and set are more commonly used) The eras

This paper mainly combines some characteristics of SQLSERVER2008 spatial database to explain some technical points of Silverlight in vector map drawing. The server side is responsible for providing data services, the client is responsible for drawing, of course, this process will encounter performance bottlenecks, but this article focuses on the map data Model tr
