Is there an easy way to find out block statements of the same type in a kt file? so far i only played around with the KtExpression method nextStatement(), using it more than once on one expression (especially when referenced) can result in null and behaviour i don’t want. e.g.: i want to iterate through a bunch of reoccurring types and save them in a list.

normally you’d use a visitor for this

ah, makes sense, thanks! 🙂

@yole so there’s like a little bit of a complicated problem i ran into. is it possible to get the parent or the whole kt file from a specific KtExpression by calling conainingKtFile?

[Timo Obereder]

it seems that i can get to the kt file but having problems reading expressions out of it even though i’m using .accept(object: KtTreeVisitorWorld() { ... })

[yole]

yes, you can use containingKtFile to get the file or .parent to get the direct parent

[Timo Obereder]

with .parent it worked 🙂 , thanks again!
