There was a problem hiding this comment.
You can just inline key and value IMO.

Hi:
I think the representation of Multimap is {1: A, 1: B, 2: C}. So when A and B are deleted, only {2: C} is left. And asMap() method returns a map in the form of {1：[A, B], 2：[C]}. In this map, {1：[], 2:[C]} is left when A and B are deleted. So wrappedCollection(key) should not be used。 It willl show as {1: A, 1: B, 2: C} when wrappedCollection(key) is used, and the asMap() method does not make sense.
