memory management - Cocos2D: What needs to be allocated? -

-

i should know can´t decide when allocate game objects when when don´t need to.

example: have pause button in game. button not allocated in way, put in input layer this: pausebutton = [ccsprite spritewithspriteframename:@"pause.png"];

i´ve done labels.

however, added character object game tutorial, this: [[[self alloc]initwithimage] autorelease]; (this line part of method)

well, how 1 decide if allocate game object or not? there practice or should allocate->autorelease add game?

actually 2 lines identical. spritewithspriteframename static function of ccsprite class. returns autorelease object.

initwithimage non-static need allocate first, since it's marked autorelease, behaves in same way.

my rule of thumb if there static functions available return auto-release objects, use them convenience sake. if remove autorelease second example, have manually call "release" on object destroy it. cannot call release on autorelease object, there may cases want destroy object (and not on scene change instance).

hope helps!

c++ - Using OpenSSL in a multi-threaded application -

-
i have been writing soap client application in c++ on ubuntu using openssl https transport , pthreads threading. have number of threads - 1 central data acquisition thread periodically gets worker threads make soap requests via shared mutex protected queues. reading documentation openssl found is openssl thread-safe? in openssl faq describes mechanisms required ensure thread safety when using openssl. implemented , works fine. the reason question conceptual difficulty really. thinking implementing same functionality application has already, instead of using threads, create 2 seperate applications : 1 worker thread (of multiple copies running) , main data acquisition thread. use tcp sockets communicate between 2 rather mutex protected queues. may bad idea not important - confusing me would have implement same functions required ensure openssl thread safety in second approach or not? my guess not have , treated independent (indeed surely must many applications use openssl) re...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
