if there’s a better way to do this

Not sure why you have an `if`there. That doesn't look like it would even compile.

myObj.asMyEnum()?.let { ... } ?: myObj.asMyOtherEnum()?.let { }

would work.

huh, right! Actually I have it like that in my code… (it compiles)

but I was wondering if there’s a better way than that, using

when

for example?

are the

...

blocks identical?

no but they return the same type

Ideally you would extract some common interface so that you can treat the MyEnum and MyOtherEnum with the same code

but in this case I need the specific values from the enums in the blocks

and then just do

val myRes = (myObj.asMyEnum() ?: myObj.asMyOtherEnum())?.computeRes()

mm no but with that I don’t have the specific enum values in

computeRes()

each block is enum-specific

Yes, you have, because

computeRes

is a member function on the enum.

You would make them implement an interface that specifies

computeRes

.

ohh I understand what you mean now

hmm but in this case it doesn’t fit to have the logic in the enums… the enums should be just state

in my particular use case I mean

ok… I think the

?:

to join the

let

blocks isn’t that bad actually, will keep that. Thanks for your help anyway 🙂

is there a more idiomatic way to do:

val msg = context.message
when (msg) {

or do I need to do this always for smart casts?

that’s idiomatic enough

If I have a java class file in my kotlin project containing a normal java class.. can I somehow alter that java class definition in kotlin, e.g. add an interface, add a ctor ?

No

@rogeralsing You can add extention funtions of course.

Anyone defined a kotlin

xfuncname

diff setting for git to show kotlin class/fun/object names in diff hunk headings?

@karelpeeters but I cannot add new fields or make it implement another interface?

No

The plugin is completely broken, doesn't recognise when I'm referencing a nonexistent variable

Doesn't have the underline for mutable properties

Nothing

I can't continue this until I figure out what's happening
