Class UndoActivity

Namespace
ActivityPub.Types.AS.Extended.Activity
Assembly
ActivityPub.Types.dll

Indicates that the actor is undoing the object. In most cases, the object will be an Activity describing some previously performed action (for instance, a person may have previously "liked" an article but, for whatever reason, might choose to undo that like at some later point in time). The target and origin typically have no defined meaning.
