@Parcelize
class RemoteDeclarationRepository : DeclarationRepositoryInterface {

    private val declareService: ProActiveDeclareApi
        get() = Api()

    override fun getDeclarations(periodId: Int, offset: Int, limit: Int): Single<DeclarationsResponse> {
        return declareService.getDeclarations(periodId, offset, limit)
    }

    override fun getDeclarationPeriod(id: Int): Single<DeclarationPeriod> {
        return declareService.getPeriod(id).map { it.data }
    }       //and so on 50 times almost

Sorry, what do you mean by `I have to write 50 times the same variable declareService inside these override functions`?

[ivano]

That inside this snippet I have almost 50 methods, and inside each of them I have to write declareService.getthis() in one function, then the same in the next declareService.getThat()

[ivano]

I would like to know if in kotlin there is a "wrapper" as the keyword with so that I can write only getThis() or getThat

[arekolek]

hmmm, maybe delegation should work?

class RemoteDeclarationRepository : DeclarationRepositoryInterface, ProActiveDeclareApi by Api() {

    override fun getDeclarations(periodId: Int, offset: Int, limit: Int): Single<DeclarationsResponse> {
        return getDeclarations(periodId, offset, limit)
    }

    override fun getDeclarationPeriod(id: Int): Single<DeclarationPeriod> {
        return getPeriod(id).map { it.data }
    }

(then ProActiveDeclareApi would be a public api of RemoteDeclarationRepository, so maybe you don’t want that :P)

[ivano]

COOL

thank you Arek!
