C# Class Akka.Cluster.Reachability

Immutable data structure that holds the reachability status of subject nodes as seen from observer nodes. Failure detector for the subject nodes exist on the observer nodes. Changes (reachable, unreachable, terminated) are only performed by observer nodes to its own records. Each change bumps the version number of the record, and thereby it is always possible to determine which record is newest merging two instances. Aggregated status of a subject node is defined as (in this order): - Terminated if any observer node considers it as Terminated - Unreachable if any observer node considers it as Unreachable - Reachable otherwise, i.e. no observer node considers it as Unreachable
