Mr Dog posted:Dependency Injection is nice for webapps, how else are you going to instantiate your fifty-odd "controllers" I use aop to wrap methods in transactions and im pretty sure mybatis-spring uses it for mapping method names in interfaces to your sql in ur mapping files. so that stuff is cool and works well. altho I don't use spring for webzones, only web services (cxf).

poo poo and AOP makes me feel like I'm being trolled. "Yes certainly, let's implicitly alter the semantics of methods if their names match certain patterns. This sounds like a very reasonable thing to do"

aop is great unless you are trying to debug code or read code or understand what code is doing in really any way

So basically the same arguments made by plangers as to why dynamic typing is a good idea (because they need to use fewer keystrokes in Sublime Text or whatever to poo poo out their latest node.js disasterpiece. text entry being the most strenuous part of programming, you see) "oh i don't do software maintenance i'm a ~*code poet*~ at an awesome new startup full of likeminded ninja coders. we'll just throw away buttframework v0.4 beta and replace it with fartframework v0.4 beta without making any end-user-visible improvements whatsoever but it'll be more ~*omakase*~ or some poo poo"

proxies own esp when you use them to write something that turns interface method calls into stored proc calls and return result sets as lists of java objects (i did this (it owns))

that's what mybatis-spring does except it can do more complex object mappings too

Naming conventions should be as follows: Files: All lower case with underscores if a space is needed. IE: butt_file Enum/Struct fields: All caps. IE: BUTTS, FARTS Objects: One word with a capital letter for each new word. IE: ButtObject Object fields: Same as objects. IE: ButtObject.Fart Comments at our place are as follows: /** * @brief Butt Function * @params None * @retval Farts /* Works out p-well for me!

spoiler look at enum  http://docs.oracle.com/javase/6/docs/api/java/lang/Enum.htmlps i might be getting something wrong but i'm sure that's how I ended up doing it. i can't recall why I needed to do it though. i think i was just trying to get my head around java generics. tef fucked around with this message at 21:02 on May 29, 2013 |

yea java generics suck poo poo but the precious loving snowflakes just love their dynamic typing, so Java is the only statically typed managed language that's actually reasonably supported these days. oop in general sucks poo poo but i can live with oop more easily than i can live with having code like def poo poo(butt): butt.do_something_i_guess_but_good_luck_figuring_out_where_this_rabbit_hole_leads() where you end up using such fantastically sophisticated source code analysis tools as grep. i mean it's that or use some lovely rear end functional language, and i'm lazy so i'll just re-use a zing i made over a year ago Mr Dog posted:Ah yes, functional programming.

"gonna fire up the stove to cook some heroin, makin myself a promise to never do it again and when the future is accessed we find im just not exceptional enough to move on with my life" this is c++ specific but im sure u could twist anything in there to fit other plangs
