Hello. Is there something more elegant than the following to invoke each lambda in a list?

lambdas.forEach { it() }

[marstran]

Isn't that pretty straight forward and elegant already?

[Moritz Post]

yes it is pretty good. i was thinking someting like forEach(::invoke) or forEach(::it) if you get my intention.

Something like this, but I’m guessing I’m missing something from the Function type.

lambdas.forEach(Function::invoke

if it can be a reference, you can set it automatically from the IDE using the actions pop up.

[mkrussel]

That’s what I normally do.

[Moritz Post]

it must be noted that the lambdas are () -> Unit .

[Moritz Post]

if they were (element) -> Unit they could fall into the forEach signature

[Javier]

I don’t know if Element::invoke could work, I am not at the computer right now to do some tests

[Moritz Post]

Element would only be the lambda.

No one stops you from creating an extension lambdas.invokeAll() 🙂

[Matteo Mirk]

Anyway, It will work as you wanted if you declare a type alias:

typealias Work = () -> Unit

lambdas.forEach(Work::invoke)
