this question has been asked (and answered) in old haxe forums on babble ... appears that entire forum system no longer functions. therefore, i'm asking here: in haxe, need declare "interface" class includes static function, "instance()." when so: you can't declare static fields in interfaces so remove word "static" public function instance() [...] , , this: field instance needed [...] missing. apparently "catch-22." there must easy solution. it? as stated language doesn't allow static fields on interfaces. choice intentional. thing doesn't exist inheriting static fields. there several ways structure code avoid such usage in point of view doesn't give many advantages. factory pattern or di approach (i suggest minject library ) seems obvious. given comment below go typedef instead of interface: typedef getinstance = void -> void; you can pass typedef around same interface advantage can us

i've decided study primary documentation in java. i've started object class , looking @ equals method. know equals using hashcode method. although, hashcode returns int there limited number of unique hashcodes can generated. what happen when try compare 2 diffrent objects have same hashcode ? posible? yes. 2 objects can have same hashcode. however, hashcode plays no role when comparing 2 objects. if want check if 2 objects of class equal , override equals , define when 2 objects of class should considered equal. if want compare if 1 object of class less than/greater other (usually while sorting collection), implement comparable , override compareto method. (you can implement comparator ) if ever want store object in hashset or use key in hashmap , make sure override hashcode method or objects hashset or keys in hashmap stored in single bucket. don't forget override equals in classes create. if don't this, 2 references object of class equ

i have entity in object model called book class attribute xyzbook . mogenerator creates 2 classes: _xyzbook xyzbook , inherits _xyzbook . so far good. if create instance on xyzbook : xyzbook *b = [xyzbook insertinmanagedobjectcontext:context]; sending class b, returns xyzbook expected. [b class] --> xyzbook however, sending ismemberofclass:[xyzbook class] returns no!!! [b ismemberofclass:[xyzbook class]] --> no it returns yes if use _xyzbook super class: [b ismemberofclass:[_xyzbook class]] --> yes so, on earth going on???? btw, create these clases using custom base class (with --base-class option mogenerator). in case has this...

i'm trying cluster million objects, each have varying length of datapoints, less 100. features date of observations , id value of each object(let's runner's(name) , times in different races). want run minibatch k-means on data, want algorithm take stratified samples based on third feature, let's u.s. state runner from. there way implement such sampling within minibatchkmeans function? if not, there way take stratified samples , pass them function somehow? thought this, seems if took stratified samples , passed them base k-means algorithm, wouldn't able aggregate samples , 1 label each object. advice?

i'm writing application must put image above video , save video. in general application opens video file, after user select image transparent background , put image above video, after user press save button new video image above video. can please provide me information or hints how that. so per question, looking video editor kind of solution achieve task.. i think scenario: ** have video in application ** open bitmap resource (image file where) ** overlay bitmap @ bottom of movie (video) on frames in background ** save video on external storage for ffmpeg support overlaying functionality or android mediacodec stuff . ffmpeg has various filters 1 of them overlay filter. understand want overlay image (i.e. png) on video, ffmpeg surely useful framework job. can set output format can set co-ordinates of image overplayed. e.g: ffmpeg -i input.avi -i logo.png -filter_complex 'overlay=10:main_h-overlay_h-10' output.avi above command adds overlay
