gf712lisitsyn: hey, are you around? Need to ask you some stuff about registering class member functions10:50
lisitsyngf712: hey10:50
lisitsynyeah10:50
gf712OK, so I need to expose a method in one of the kernels10:51
lisitsynah yeah10:51
gf712it's a corner case10:51
lisitsynI've seen that thing Heiko mentioned me10:51
lisitsyn:)10:51
lisitsynso you need a method that you can call by string?10:51
gf712ah yes, so he mentioned adding a SGObject::run(std::string method_name)10:51
gf712yes, for example10:52
gf712I guess it's the way to do it?10:52
lisitsynI guess we can emulate that using lazy?10:52
lisitsynlike lazy parameter we had10:52
lisitsynI don't know any better way so far10:52
lisitsynthe most tricky unresolved thing10:52
lisitsynis how to pass parameters to such methods10:52
gf712yup, but in this case it should be fine10:53
gf712can add it as a parameter10:53
gf712and then raise an error if it hasnt been set10:53
gf712rather than passing it as an argument to the function10:53
lisitsynyeah10:53
lisitsynmight make sense10:54
gf712how are the lazy functions called by the user in the interface btw?10:54
lisitsyngf712: you get('something') and it is computed11:00
lisitsyngf712: it is basically a trick in an11:00
lisitsynany11:00
lisitsynthat stores std::function<T()>11:00
gf712lisitsyn: ah ok!11:00
gf712but it can't be void right?11:00
lisitsynyeah I guess you have to return some bool or so11:00
gf712OK! thanks!11:01

@wikinggf712: here?12:29
gf712wiking: yes I am here12:33
@wikingjust wondering about the READ_ONLY story12:34
@wikingwhy dont we just declare the variable const? : )12:34
@wikingsorry if i missed the explanation12:34
gf712I think Heiko tried it but was getting lots of issues12:34
gf712I havent tried it myself12:34
@wikingmmmm12:34
@wikingweird12:35
@wikingi mean yeah you cannot create a dense features with the default ctor for sure then12:35
@wikingbut i guess that's the point :)12:35
gf712here is the conversation http://shogun.ml/irclog/2019-03-01/#t15:3312:36
gf712I can't really remember much let me reread12:36
gf712wiking: ah apparently the const won't play along nicely std::shared_ptr12:37
@wikingshared_ptr? :)12:37
@wikingwhere does shared_ptr comes in play here? :)12:37
* wiking is lost12:37
gf712I guess at some point we'll just use shared_ptr? I am not sure!12:38
@wikingmmmm12:38
gf712you'll have to ask lisitsyn12:38
@wikingthnx12:39

gf712lisitsyn: ah ok! I am not sure I understand then what the issue is with using const to enforce users can't change lhs and rhs with put?13:50
