Interface EventService

Parameters

• eventKeys: Set<EventKey>

  Set of event keys against which event are fetched.

Returns Promise<Event[]>

Parameters

• subsystem: "AOESW" | "APS" | "CIS" | "CLN" | "CRYO" | "CSW" | "DMS" | "DPS" | "ENC" | "ESEN" | "ESW" | "HNDL" | "HQ" | "IRIS" | "LGSF" | "M1COAT" | "M1CS" | "M1S" | "M2COAT" | "M2S" | "M3S" | "MODHIS" | "NFIRAOS" | "OSS" | "REFR" | "SCMS" | "SER" | "SOSS" | "STR" | "SUM" | "TCS" | "TINS" | "WFOS" | "Container"

  subscription to be made under the subsystem

• maxFrequency: number

  the duration which determines the frequency with which events are received

• pattern: string

  optional pattern to match against the event key.supported glob-style patterns

                     - h?llo subscribes to hello, hallo and hxllo
                     - h*llo subscribes to hllo and heeeello
                     - h[ae]llo subscribes to hello and hallo, but not hillo
  

Returns (onEvent: (event: Event) => void, onError?: (error: ServiceError) => void, onClose?: () => void) => Subscription

• • (onEvent: (event: Event) => void, onError?: (error: ServiceError) => void, onClose?: () => void): Subscription

  • This API subscribes to events of all the EventKeys specified using a Subsystem and a pattern to match the remaining Event Key and return subscription handle which can be used as a kill switch. It takes callback function which gets triggered when ever the events are received. The latest events available for the given Event Keys will be received first.

    Parameters

    • onEvent: (event: Event) => void

      the function which gets triggered on receiving an event

      • • (event: Event): void

        • Parameters

          • event: Event

          Returns void

    • Optional onError: (error: ServiceError) => void

      a optional error callback which gets called on receiving error. it can be Parsing error or a Runtime error [for ex. Gateway exception]

      • • (error: ServiceError): void

        • Parameters

          • error: ServiceError

          Returns void

    • Optional onClose: () => void

      a optional close callback which gets called when the connection is closed.

      • • (): void

        • Returns void

    Returns Subscription

    Subscription

Parameters

• event: Event

  the event to be published

Returns Promise<"Done">

Parameters

• eventKeys: Set<EventKey>

  Set of event keys to be subscribed.

• maxFrequency: number

  the duration which determines the frequency with which events are received

Returns (onEvent: (event: Event) => void, onError?: (error: ServiceError) => void, onClose?: () => void) => Subscription

• • (onEvent: (event: Event) => void, onError?: (error: ServiceError) => void, onClose?: () => void): Subscription

  • This API subscribes to multiple eventKeys and receive events at every frequency and return subscription handle which can be used as a kill switch. It takes callback function which gets triggered when ever the events are received. The latest events available for the given Event Keys will be received first.

    Parameters

    • onEvent: (event: Event) => void

    • Optional onError: (error: ServiceError) => void

      a optional error callback which gets called on receiving error. it can be Parsing error or a Runtime error [for ex. Gateway exception]

      • • (error: ServiceError): void

        • Parameters

          • error: ServiceError

          Returns void

    • Optional onClose: () => void

      a optional close callback which gets called when the connection is closed.
