Class ThreadWorker<Data, Response>

A thread worker used by a poolifier ThreadPool.

When this worker is inactive for more than the given maxInactiveTime, it will send a termination request to its main thread.

If you use a DynamicThreadPool the extra workers that were created will be terminated, but the minimum number of workers will be guaranteed.

Properties

activeInterval?: Timeout

Handler id of the activeInterval worker activity check.

isMain: boolean

Whether this is the main worker or not.

lastTaskTimestamp: number

Timestamp of the last task processed by this worker.

opts: WorkerOptions = ...

Options for the worker.

port: MessagePort

Message port used to communicate with the main worker.

statistics: WorkerStatistics

taskFunctions: Map<string, WorkerFunction<Data, Response>>

Accessors

Methods

  • Returns number

    The unique asyncId assigned to the resource.

  • Binds the given function to execute to this AsyncResource's scope.

    Type Parameters

    • Func extends ((...args) => any)

    Parameters

    • fn: Func

      The function to bind to the current AsyncResource.

    Returns Func

    Since

    v14.8.0, v12.19.0

  • Call all destroy hooks. This should only ever be called once. An error will be thrown if it is called more than once. This must be manually called. If the resource is left to be collected by the GC then the destroy hooks will never be called.

    Returns ThreadWorker<Data, Response>

    A reference to asyncResource.

  • Handles an error and convert it to a string so it can be sent back to the main worker.

    Parameters

    • e: string | Error

      The error raised by the worker.

    Returns string

    The error message.

  • Call the provided function with the provided arguments in the execution context of the async resource. This will establish the context, trigger the AsyncHooks before callbacks, call the function, trigger the AsyncHooks after callbacks, and then restore the original execution context.

    Type Parameters

    • This

    • Result

    Parameters

    • fn: ((this, ...args) => Result)

      The function to call in the execution context of this async resource.

        • (this, ...args): Result
        • Parameters

          • this: This
          • Rest ...args: any[]

          Returns Result

    • Optional thisArg: This

      The receiver to be used for the function call.

    • Rest ...args: any[]

      Optional arguments to pass to the function.

    Returns Result

    Since

    v9.6.0

  • Returns number

    The same triggerAsyncId that is passed to the AsyncResource constructor.

  • Binds the given function to the current execution context.

    Type Parameters

    • Func extends ((this, ...args) => any)

    • ThisArg

    Parameters

    • fn: Func

      The function to bind to the current execution context.

    • Optional type: string

      An optional name to associate with the underlying AsyncResource.

    • Optional thisArg: ThisArg

    Returns Func
