Is there something like `Function1` but as consumer, so without return value?

Is there something like Function1 but as consumer, so without return value?

[Youssef Shoaib [MOD]]

A Function1<T, Unit> should do the job just fine. Or alternatively if you need a proper interface use a fun interface Consumer<T> { fun consume(t: T): Unit }

[Vampire]

Ah, thanks, the Function1<T, Unit> was exactly what I needed

[Ruckus]

Why not just (T) -> Unit?

[louiscad]

I think you want Function0, or just use the functional type (you can implement it like an interface).

[Vampire]

Function0 would give me 0 parameters and 0 or 1 return type, but I needed 1 parameter and 0 return type, so Function1<T, Unit> was exactly what I needed.

(T) -> Unit didn't work because I needed it as generic type argument like object : TypeOf<Function1<T, Unit>>() {}

[Youssef Shoaib [MOD]]

@Vampire hate to be the um actually guy, but AFAIK object : TypeOf<(T) -> Unit>() {} would still work just fine

[Vampire]

Hm, strange, I was sure I tried that and it didn't work but works now.
Probably some typo I had, thanks.
