objective c - How to properly init RestKit's objectStore to use directory other than Documents -

-

so see there init method in restkit's reference: objectstorewithstorefilename:indirectory:usingseeddatabasename:managedobjectmodel:delegate suppose initialize objectstore in specified directory. "indirectory" parameter accepts nsstring. i've tried @"library/caches" , [self.applicationcachesdirectory absoluteurl] self.applicationcachesdirectory returns url of caches directory i'm getting exceptions.

please tell me how can specify "library/caches" in method in order save sqlite db in caches directory instead of documents?

got working. i've created helper method caches folder path nsstring

    - (nsstring *)applicationcachesdirectorystring {     nsarray *paths = nssearchpathfordirectoriesindomains(nscachesdirectory, nsuserdomainmask, yes);     nsstring *cachepath = [paths objectatindex:0];     bool isdir = no;     nserror *error;     if (! [[nsfilemanager defaultmanager] fileexistsatpath:cachepath isdirectory:&isdir] && isdir == no) {         [[nsfilemanager defaultmanager] createdirectoryatpath:cachepath withintermediatedirectories:no attributes:nil error:&error];     }     return cachepath; }

and passed objectstore init method:

self.objectmanager.objectstore = [rkmanagedobjectstore objectstorewithstorefilename:databasename indirectory:[self applicationcachesdirectorystring] usingseeddatabasename:seeddatabasename managedobjectmodel:managedobjectmodel delegate:self];

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...
