- - ### Uses of IContext in org.apache.storm.daemon.supervisor

    Methods in org.apache.storm.daemon.supervisor with parameters of type IContext
    Modifier and Type | Method and Description
    --- | ---
    `static ContainerLauncher` | ContainerLauncher.`make(Map<String,Object> conf, String supervisorId, int supervisorPort, IContext sharedContext, StormMetricsRegistry metricsRegistry, ContainerMemoryTracker containerMemoryTracker, Supervisor.Iface localSupervisor)` Factory to create the right container launcher for the config and the environment.

    Constructors in org.apache.storm.daemon.supervisor with parameters of type IContext
    Constructor and Description
    `LocalContainer(Map<String,Object> conf, String supervisorId, int supervisorPort, int port, LocalAssignment assignment, IContext sharedContext, StormMetricsRegistry metricsRegistry, ContainerMemoryTracker containerMemoryTracker, Supervisor.Iface localSupervisor)`
    `LocalContainerLauncher(Map<String,Object> conf, String supervisorId, int supervisorPort, IContext sharedContext, StormMetricsRegistry metricsRegistry, ContainerMemoryTracker containerMemoryTracker, Supervisor.Iface localSupervisor)`
    `Supervisor(Map<String,Object> conf, IContext sharedContext, ISupervisor iSupervisor, StormMetricsRegistry metricsRegistry)` Constructor for supervisor daemon.

  - ### Uses of IContext in org.apache.storm.daemon.worker

    Constructors in org.apache.storm.daemon.worker with parameters of type IContext
    Constructor and Description
    `Worker(Map<String,Object> conf, IContext context, String topologyId, String assignmentId, int supervisorPort, int port, String workerId, Supplier<SupervisorIfaceFactory> supervisorIfaceSupplier)` TODO: should worker even take the topologyId as input? this should be deducible from cluster state (by searching through assignments) what about if there’s inconsistency in assignments? -> but nimbus should guarantee this consistency.
    `WorkerState(Map<String,Object> conf, IContext mqContext, String topologyId, String assignmentId, Supplier<SupervisorIfaceFactory> supervisorIfaceSupplier, int port, String workerId, Map<String,Object> topologyConf, IStateStorage stateStorage, IStormClusterState stormClusterState, Collection<IAutoCredentials> autoCredentials, StormMetricRegistry metricRegistry)`
