All Implemented Interfaces:
IRequestUpdateListener, Comparable<IRequestUpdateListener>
public final class CircuitBreaker
extends NetworkPattern
implements IRequestUpdateListener
Manager class of all CircuitBreakers of one Microservice Instance.

Creates a CircuitBreakerState for each connection to another Microservice of the owning MicroserviceInstance

This class is a NetworkPattern and therefore monitors all requests send by its owning MicroserviceInstance.

      Description copied from interface: IRequestUpdateListener
      Listener for the successful completion of the sending process. Provides a reference to the successfully arrived request.
      Specified by:
      onRequestArrivalAtTarget in interface IRequestUpdateListener
      Parameters:
      request - request that triggered this event
      when - time of this event
      Returns:
      true if the request was terminally handled (consumed) by this instance

    • onRequestResultArrivedAtRequester

      public boolean onRequestResultArrivedAtRequester​(Request request, desmoj.core.simulator.TimeInstant when)
