Accessors

connectionFailure

  • get connectionFailure(): ISignal<this, Error>

  • A signal emitted when there is a connection failure.

    Returns ISignal<this, Error>

isDisposed

  • get isDisposed(): boolean

isReady

  • get isReady(): boolean

ready

  • get ready(): Promise<void>

runningChanged

  • get runningChanged(): ISignal<this, IModel[]>

specs

specsChanged

Methods

Private _onChanged

  • _onChanged(model: IModel): void

Private _onStarted

Private _onTerminated

  • _onTerminated(id: string): void

connectTo

dispose

  • dispose(): void

findById

  • findById(id: string): Promise<IModel>

findByPath

  • findByPath(path: string): Promise<IModel>

refreshRunning

  • refreshRunning(): Promise<void>

  • Force a refresh of the running sessions.

    Returns Promise<void>

    A promise that with the list of running sessions.

    Notes

    This is not typically meant to be called by the user, since the manager maintains its own internal state.

refreshSpecs

  • refreshSpecs(): Promise<void>

  • Force a refresh of the specs from the server.

    Returns Promise<void>

    A promise that resolves when the specs are fetched.

    Notes

    This is intended to be called only in response to a user action, since the manager maintains its internal state.

Protected requestRunning

  • requestRunning(): Promise<void>

  • Execute a request to the server to poll running kernels and update state.

    Returns Promise<void>

Protected requestSpecs

  • requestSpecs(): Promise<void>

  • Execute a request to the server to poll specs and update state.

    Returns Promise<void>

running

  • running(): IIterator<IModel>

shutdown

  • shutdown(id: string): Promise<void>

shutdownAll

  • shutdownAll(): Promise<void>

startNew

stopIfNeeded

  • stopIfNeeded(path: string): Promise<void>

  • Find a session associated with a path and stop it if it is the only session using that kernel.

    Parameters

    • path: string

      The path in question.

    Returns Promise<void>

    A promise that resolves when the relevant sessions are stopped.
