Instance Constructors

  1. new DelegatingMutableHealthQuasiComponent(loggerFactory: NamedLoggerFactory, name: String, timeouts: ProcessingTimeout, reduceState: (Map[Id, H.State]) => H.State)

    reduceState

    Computes the aggregate health state of the component given the health states of all dependencies. When given the empty map, produces the initial state.

    First removes all dependencies in remove, then adds all those in add.

    First removes all dependencies in remove, then adds all those in add. If an ID appears in remove and add, then the ID is replaced. Refreshes the state if any of the dependencies was changed.

    Updates of dependencies are not atomic: If this method is called concurrently multiple times, the resulting dependencies may not correspond to a serializable execution.

    If an dependency triggers a concurrent state refresh, then the state refresh may see an inconsistent set of dependencies and therefore derive an inconsistent state. This however is only temporary as in this case another state refresh will be triggered at the end.
