A group is a dynamic set of
T
-typed values. It is used to represent dynamic hosts and operations over such lists. Its flexibility is derived from the ability to map, creating derived groups. The map operation ensures that each element is mapped over exactly once, allowing side-effecting operations to rely on this to implement safe semantics.Note: querying groups is nonblocking, which means that derived groups are effectively eventually consistent.
Note:
T
s must be hashable, definininghashCode
andequals
to ensure that maps have exactly-once semantics.Note: Groups are invariant because Scala's Sets are. In the case of sets, this is an implementation artifact, and is unfortunate, but it's better to keep things simpler and consistent.
