I want to learn about design patterns, and everywhere I see diagrams like this:
Is it UML or something else? I just need a short link to find out what each of the different lines means? which is inheritance etc.
1 Yes, this is UML. You can read more (with examples) about class diagrams and other UML diagrams, for example. at http://www.uml-diagrams.org/class-diagrams-overview.html
2 Although Google can print and pin " UML cheat sheet" or " UML quick reference card" on its bulletin board (for example, http://www.holub.com/goodies/uml ).
