Detailed Description
Marker interface for entities aware of the wiki they belong to.
Instances of classes implementing this interface belong to a specific wiki and may be used in a cross-wiki context. Services using these classes have to ensure the entities they operate on belong to the correct wiki by calling assertWiki().
Additionally, some getters of implementing classes can take an optional $wikiId parameter to assert on for extra protection against incorrect cross-wiki access. The parameter should be added if using the property in the context of a wrong wiki will cause DB corruption. Usually the rule of thumb is fields which are commonly used as foreign keys, like page_id, rev_id, user_id, actor_id etc. However, the exact line is left to the best judgement of the implementers.
Examples: RevisionRecord::getId() or PageIdentity::getId()
