This is my implementation of the Design Patterns from the book 'Design Patterns: Elements of Reusable Object-Oriented Software' Erich Gamma, Richard Helm, Ralph Johnson, John Vlissides ISBN 0-201-63361-2 Copyright 1995 21th Printing, November 2000 The webpage and official 'code' for this book were previously available from [1] http://st-www.cs.illinois.edu/users/patterns/DPBook/DPBook.html [2] http://st-www.cs.illinois.edu/patterns/dpbook/Source.html (TODO: link [1] and [2] no longer work. Does anybody know the new location of the 'official' source code for the book?) The nice thing about the book is that it is... well... not complete :-) To come to a complete working implementation of all the Design Patterns presented in the book, and be able to play with them, requires some extra coding. The goal of this project is to actually provide the missing pieces and come to something that will compile and run cleanly. On the following websites, I have found some more C++ code that helped me complete everything: [3] http://www.c-jump.com/CIS75/Week11/ [4] http://www.c-jump.com/Download/Patterns/Prototype/html/ [5] https://code.google.com/p/basic-algorithm-operations/source/browse/trunk/DP [6] http://dislab.hufs.ac.kr/wiki/Lecture/Design_Pattern [7] http://blog.csdn.net/joey_zoy/article/details/5610810 [8] https://github.com/wangqiang8511/C---Design-Patterns-Examples/ And here are some interesting slides that give some more explanation: [9] http://www.cs.toronto.edu/~penny/teaching/csc407/ A more modern C++11 approach using Boost libraries was given in a talk by Tobias Darm given here: http://www.infoq.com/presentations/gof-patterns-c-plus-plus-boost An interview from 2009 with the GoF authors is given here: http://www.informit.com/articles/article.aspx?p=1404056 A dependency analysis and refactoring of the Gang of Four examples can be found at https://github.com/zebmason/GoFRefactored/blob/master/README.md Feel free to send me your comments, suggestions and improvements in the form of a git pull request!
