Don't forget iterator, interceptor, etc. We don't bother to track which design patterns are in use in Tomcat. Some of them are obvious due to their class names or behavior, but there is no documentation about what is being used where. There is also the problem of having a very large number of named design patterns, many of which are variations on a theme. You may see code that looks like publish/subscribe and others may call that observer/observable, etc. Some patterns are so obvious as to not require naming at all (e.g. "State"). If you'd like to hunt through the code and find examples of carious patterns and document them -- e.g. in the Wiki -- that would be fine, but I don't think any committer is currently interested in such a task. - -chris -----BEGIN PGP SIGNATURE----- Comment: Using GnuPG with Thunderbird - https://www.enigmail.net/ iQIzBAEBCAAdFiEEMmKgYcQvxMe7tcJcHPApP6U8pFgFAl3uf/oACgkQHPApP6U8 pFgieQ/+LSNxlzLoM8XBtE/sNQlM+HXokdAAenakQb7jGHzKYGo7ElBL3+o0FORg /4HRQYO7sO9PkWDmBY8oAlxlXPdCwx6KSkK2ZFMi8kW4cOabqLXl0l7KpOI2TGNK u7aq7jJxN8k/OmcBdlIutYpKScB//kp9wDei6G2lEGdoQh2qMMgsWN7q9J9IGAO2 CTB3JMVTy2LQGbXSPBGhNgRhpL4DykoHqpLCflsA9rhPGFVnN+cnCsFmiI3XREHD N/ap5ffXA2yOeOIuR5vhBolQJ2/3bGOQdIUrliGXMEv2hefslP+fQYudOAYzapju MO5VBVwOhtL0cZlVdOAgMJRL4V/Y91rSIXIS1gw/RKGV5cdEl+6VoyQhEVmRQa6u gHQ2HWrT+MyAV72YBulalPJy3c1vlr3Lna5kJFsxWB9rwdGZLv2xWIrWmINecdI1 GAadRCzI0QOPA1leoq0ZdjtLvuk3W0m9+98V/uy9nrz6eyZ2hm2dFoTRvM2bbLda +aSwQssfaiq3QyoOxOmpeb3tWzQMXHeeoq6u5tnCwktNXUV78ZE4q6IiU9wcW8/L Z1/0VwhEWTF/cP8MSnqhMquEYoFVnFv2HBRE8eYIshKw2KrnlIzjYwGHCYqjRTNK DNSYvvuzf7s5pdzG7EtrrvOVNW7mH5Qtvs2hx1C55BijJRf3Rx0= =aczA -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
