…and for my next rant I wax poetic about the joys of writing code in the morning using C++ containers and in the afternoon switching to Java!<\/p>\n
So I’ve got me an array of, I dunno uint32_t’s, and I’m just happy as a clam with my fun member functions and I’m callin’ ’em and I’m doing all sorts of cleverness, and then it comes time to do something with my amusingly arranged array. I need to call something that takes a pointer to an array of uint32_t’ or better yet I need to manipulate my fancy C++ array very quickly. No problem, this is still C isn’t it, bloated and strange but I can still get a pointer, why yes I can. A quick call to array::data() and I get me a pointer to an array of uint32_t’s…but not just any array of uint32_t’s _the_ array, not a copy (that the cpu had to do a shit load of work to make) the real thing… and I can do what I want with this array, may not be wise but I’m good to go!<\/p>\n
…and later that day I’m writing some Java; and I got me a SortedSet… clever… arrange… member functions… But now I gotta call some Android crap and it wants an array because it’s going to display it somewhere. So I go to the documentation and I read, “toArray() Returns an array containing all elements contained in this set.” and I’m having flashbacks to this morning and I think jammin! I’ll just use these cutesy member functions to cleverly arrange my set and then I’ll call this refresh (update whatever) method and I already passed Android a reference to the underlying array and viol-la! …and it doesn’t bloody work. Well, it works the first time but I make my member calls on the set and I call refresh and I get the same display I got last time. So I reread the docs, it says, “toArray() Returns an array containing all elements contained in this set,” so what’s the problem… wait for it… Returns an<\/strong> array containing all elements contained in this set not the<\/strong> array. Effing Java decided to copy the whole bloody thing to a new array and then has the temerity to hand me a reference to this useless (and CPU intensive) pile of crap. Arrrgghh, I hate Java. Yeah, yeah, yeah, copy on write whatever, memset this pal!<\/p>\n","protected":false},"excerpt":{"rendered":" …and for my next rant I wax poetic about the joys of writing code in the morning using C++ containers and in the afternoon switching to Java!
