Ok, assuming I don't want to include any further services. I have in the deleteDocument, the IOutputDeleteActivity but the addOrReplaceDocument is taking the IOutputAddActivity. Which is the proper way to instantiate IOutputAddActivity from the IOutputDeleteActivity ? Because they are different interfaces and i don't know exactly which implementation arrives there, should I do a hardcoded casting ? Or what else?
