what to replace ? with in kotlin when we don’t know what will type be at runtime and it’s definition isn’t gonna participate in any method signature of this interface

[adamd]

have you tried Any?

[nimtiazm]

yes it’s a recursive bound. to keep it open I use ? in java

[nimtiazm]

using Any is similar to using star projection. so it doens’t work

[nimtiazm]

T and U are simply input and output in one CStage and U is input in another CStage where output is unknown

[nimtiazm]

actually in the interface, the method signatures utilize T, U and N only so it works out nicely

[nimtiazm]

yes

[nimtiazm]

It has to be this way because U (output) from first CStage replaces T (input) in second CStage

[nimtiazm]

i’m using it without any problem.

[nimtiazm]

if i use

CStage<T, U, N: CStage<U, *, N>>

i can’t use any other CStage for N

[Kroppeb]

@Ruckus T and U aren't bound together though?

[nimtiazm]

no there are no bounds for T and U

[nimtiazm]

only N is recursively bound because it has to implement CStage

[Kroppeb]

lol did he delete all his msgs?

[Ruckus]

@Kroppeb Yes, I did. Sorry about that. I was getting frustrated with the conversation and didn't want to get any more notifications for it. I was operating under the false impression that deleting my comments would unsubscribe me from this thread. On the bright side, I have now discovered the (very large and obvious) "Unfollow thread" action.
