View Source Finitomata.ClusterInfo behaviour (Finitomata v0.22.0)

The behaviour to be implemented for locating the node across the cluster.

Infinitomata comes with a default naïve implementation, which simply responds with a determined random value for whois/1 and with all visible nodes list for nodes/0.

The call to Finitomata.ClusterInfo.init/1 passing the module implementing the desired behaviour is mandatory before any call to Infinitomata.start_fsm/4 to preserve a determined consistency.
