16x20" and larger are printed on a beautiful flat matte canvas material.

8x10" and 11x14" are printed on a premium watercolor textured paper. Framing can be added separately here.Įach map is drawn digitally by hand with a watercolor style and texture, giving close attention to every detail on the course, from bunkers, water hazards, tee boxes, fairways and greens. I reference aerial satellite images to establish the course layout, but if you have any special requests or want to provide additional layouts and renderings that's ok too! On the wall at home or in the office, custom course maps tell a story and provide a beautiful way to showcase your passion for golf. These watercolor-style maps are minimal, yet personal pieces of art decor. which is undesirable in client scenarios.A custom golf course map makes the perfect gift for any golfer. This solution will also work but its very bad as operator < will be overloaded universally for your data type/class. Overloading operator< for your user defined data type. Note: You need to create specialized std::less for every user defined data type(if you want to use that data type as key for cpp maps).

Nodes who's element compares less than that of the parent node are placed on the left of the parent and nodes whose elements compare greater than the parent nodes element are placed on the right.įor each node, struct lessīool operator() (const M圜lass& lhs, const M圜lass& rhs) const.

BSTs compare elements of nodes to determine the organization of the tree.

Basically maps in cpp are implemented as Binary Search Trees.

The right solution is to Specialize std::less for your class/Struct. Then you can use it instead of a friend declaration (i.e. However, if you have an access function for your private member, for example getId() for id, as follows: class Class1 If you wonder about the correct syntax, here it is: class Class1įriend struct Class1Compare // Use this for Pavel's first solution.įriend struct std::less // Use this for Pavel's second solution. In this case, VS2013 throws the following error for me:Įrror C2248: 'Class1::id' : cannot access private member declared in class 'Class1'Īs mentioned by SkyWalker in the comments on Pavel's answer, using a friend declaration helps. Both solutions presented by Pavel won't compile if the member to be compared (such as id in the question's code) is private. I'd like to expand a little bit on Pavel Minaev's answer, which you should read before reading my answer.

The advantage of this is that it will be picked by std::map "by default", and yet you do not expose operator< to client code otherwise. It just so happens that the default for the third template parameter of std::map is std::less, which will delegate to operator struct lessīool operator() (const Class1& lhs, const Class1& rhs) const What does it mean? Also, why is it only happening with user-defined types?
