03/17/2020, 6:01 AMok thanks a lot @Mike Conley, I'll read about type erasure👍 1 - a
Alessandro Tagliapietra
03/17/2020, 6:05 AMoh there are also some kotlin specific docs about it https://kotlinlang.org/docs/reference/typecasts.html#type-erasure-and-generic-type-checks - m
Mike Conley
03/17/2020, 6:05 AMright. it's a concept from java - m
Mike Conley
03/17/2020, 6:06 AMthe short story is that it exists for compatibility with code that came before generics were a thing. - m
Mike Conley
03/17/2020, 6:07 AMgenerics happen in the compiler, the vm itself doesn't know they exist, because they didn't want to change the byte code and introduce incompatibility. - a
Alessandro Tagliapietra
03/17/2020, 6:07 AMGotcha - m
Mike Conley
03/17/2020, 6:07 AMso this puts limits on what you can and can't distinguish with generics. - a
Alessandro Tagliapietra
03/17/2020, 6:07 AMwell since I've a limite set I can just use
and throw in the default caseis - m
Mike Conley
03/17/2020, 6:07 AMat runtime your two functions would be the same in bytecode, so not allowed.👍 1 - m
Mike Conley
03/17/2020, 6:08 AMyeah, you can do
, but a generic function will do the trick for you nicely as wellis - u

03/19/2020, 4:45 PMSince 1.3.70, you can solve the “String and map builders” Kotlin Koan without doing anything 😆 because the solution is to re-implement the stdlib version… Probably it should task you to implement it with a different name😄 1 - m
Michael Limb
03/19/2020, 7:44 PMHey, i have a public data class like so: - m
Michael Limb
03/19/2020, 7:45 PMCopy codedata class SomeClass( var name: String internal var featureTypeTriggers: List<PendingFeatureTypeTrigger> = emptyList() ) - m
Michael Limb
03/19/2020, 7:46 PMI want name to be accessible from outside the package, but featureTypeTriggers should only be accessible from inside the package. - m
Michael Limb
03/19/2020, 7:46 PMHence I've made
internal as wellPendingFeatureTypeTrigger - m
Michael Limb
03/19/2020, 7:46 PMbut then I get this error: - m
Michael Limb
03/19/2020, 7:46 PM'public' function exposes its 'internal' parameter type argument PendingFeatureTypeTrigger - e
