Known Direct Subinterfaces

org.terracotta.statistics.OperationStatistic

Type Parameters

Operation observers track the occurrence of processes which take a finite time and can potential terminate in different ways.

Operations must have an associated enum type that represents their possible outcomes. An example of such an enum type would be:

enum PlaneFlight {
  LAND, CRASH;
}

Operations also have an associated parameter the use of which is left up to the implementors of both the producer and consumer of events.
