• getNextJob(token, __namedParameters?): Promise<Job<DataType, ResultType, NameType>>

• Returns a promise that resolves to the next job in queue.

  Parameters

  • token: string

    worker token to be assigned to retrieved job

  • Optional __namedParameters: GetNextJobOptions

  Returns Promise<Job<DataType, ResultType, NameType>>

  a Job or undefined if no job was available in the queue.

isPaused
