@HeikoSlisitsyn: jojo20:28
lisitsynHeikoS: hey20:29
@HeikoSlisitsyn: I want your opinion on some20:29
lisitsynsure20:29
@HeikoSI have these label conversion methods20:29
@HeikoSmulticlass_labels(CLabels*)20:29
@HeikoSCMulticlassLabels* multiclass_labels(CLabels*)\20:30
@HeikoSso now20:30
@HeikoSI am in a situation where I only have a const pointer20:30
@HeikoSi.e.20:30
@HeikoSconst CLabels*20:30
@HeikoSactually sorry, the method is Some<CMulticlassLabels> multiclass_labels(CLabels* orig);20:30
@HeikoSso now how does that const stuff translate to some?20:30
@HeikoSi.e. something where I can only call const methods on20:30
@HeikoSI guess we will have this problem also when we  move to some everywhere with our const methods20:31
@HeikoSlisitsyn: see the problem?20:31
lisitsynnot yet, reading20:31
lisitsyn:)20:31
@HeikoSbasically i need some for const pointer20:32
lisitsyninteresting20:32
@HeikoSit should only allow the -> operator for const methods20:33
@HeikoSwould that be just20:34
@HeikoSSome<const CMulticlassLabels> multiclass_labels(const CLabels* orig);20:34
@HeikoS?20:34
lisitsynor 'const Some<CMulticlassLabels>"20:34
lisitsyn:)20:34
@HeikoShttps://stackoverflow.com/questions/17793333/difference-between-const-shared-ptrt-and-shared-ptrconst-t?utm_medium=organic&utm_source=google_rich_qa&utm_campaign=google_rich_qa20:34
@HeikoSbut also20:34
lisitsynah right20:35
@HeikoSI would like to avoid to have to define the casting thing some const as well20:35
lisitsynSome<const CMulticlassLabels>20:35
lisitsynbut this is going to be quite strange20:35
lisitsyndo you really want constness here?20:35
@HeikoSwell20:35
@HeikoSI only have the const pointer to labels20:36
@HeikoSand I want to convert20:36
@HeikoSah20:36
@HeikoSyeah so either this just casts ( if possible(20:36
@HeikoSor it creates a new object and converts the entries20:36
lisitsynHeikoS: I am a bit worried about adding consts around20:37
lisitsynbecause swig would multiplicate20:37
@HeikoSwe can also remove const20:37
@HeikoSbut that is not nice20:37
@HeikoSwe want const labels and const features20:37
@HeikoSfor thread safety etc20:38
@HeikoSI guess20:38
@HeikoSthe problem is the casting20:38
@HeikoSthe labels conversion thingi20:38
@HeikoSif it creates a new obj all is good20:38
@HeikoSbut the casting gives me a reference to the same thing20:38
@HeikoSso there  need to respect the const20:38
@HeikoSi think20:39
@HeikoSI will just add20:39
@HeikoSSome<const CMulticlassLabels> multiclass_labels(const CLabels* orig);20:39
@HeikoSit is just internal20:39
@HeikoSnot exposed20:39
lisitsynah ok20:39
lisitsynif it is not swig20:39
lisitsynthat sounds ok20:39
lisitsynlet me just check one thing20:39
lisitsynah ok nevermind20:39
lisitsynlet me know if it fails20:40
@HeikoSit is duplicate code20:40

@HeikoShttps://github.com/shogun-toolbox/shogun/blob/develop/src/shogun/labels/MulticlassLabels.cpp#L22620:40
@HeikoSlisitsyn: ^20:41
lisitsynhaha FLOODER20:41
@HeikoShaha :D20:41
lisitsynHeikoS: just one quite abstract idea20:41
lisitsynwould it be possible to ensure constness some other way20:42
lisitsynnot using the const? :)20:42
lisitsynbut nevermind20:42
@HeikoSi dont like all the duplicate code20:45
@HeikoSlisitsyn:20:45
lisitsynyeah me neither20:45
@HeikoSmaybe template with trait?20:46
lisitsynyeah20:46
lisitsynthat's what I thought of20:46
@HeikoSdoes is_same work for that?20:46
lisitsynspecialize for std::decay<T> == CLabels20:46
@HeikoSah20:46
@HeikoSmaybe we are thinking of different stuff20:46
@HeikoSah no20:48
@HeikoSlisitsyn: I dont think it works20:48
@HeikoSSome<CMulticlassLabels> multiclass_labels(CLabels* orig);20:48
lisitsynyeah20:48
@HeikoSwhats the template type?20:48
@HeikoSbecause we want to add const on both CLabels and CMulticlassLabels20:48
lisitsynyeah not trivial20:49
lisitsynHeikoS: I don't see any easy way yet20:50
@HeikoSmacros :D20:50
@HeikoSthe best (tm)20:50
@HeikoSlisitsyn: discards qualifiers nightmare20:56
lisitsynHeikoS: our objects semantics is not really well suited for constness20:57
@HeikoSlisitsyn: how to ensure constness?20:57
@HeikoSI have already blocked put of CFeatures20:57
@HeikoSvia overloading it20:57
@HeikoSbut i think dropping c++ const is not the best idea20:57
@HeikoSneed to patch Some::from_raw, SGObject::as, and the labels20:59
@HeikoSgnaaaa20:59
@HeikoSok dinner timer will do this later20:59
@HeikoSsee you20:59

lisitsynshubham808 hey21:13
shogitter(shubham808) How do I write obj->as<CBinaryLabels>() in python example21:14
shogitter(shubham808) Currently in python it's like LabelsFactory.to_binary(obj) but we are getting rid of CLabelsFactory21:17
lisitsynuh we need Heiko there21:45
