scheduleRequest

• scheduleRequest(identiy: Identiy, getPriority?: ((identiy: Identiy) => number)): Promise<{ done: any }>

  When the returned promise resolved, it is OK for the application to issue a request. The promise resolves to an object that contains a done method. When the application's request has completed (or failed), the application must call the done function

  Parameters

  • identiy: Identiy

    Identiy

  • getPriority: ((identiy: Identiy) => number) = ...

    will be called when request "slots" open up, allowing the caller to update priority or cancel the request Highest priority executes first, priority less than 0 cancels the request

    • • (identiy: Identiy): number

      • Parameters

        • identiy: Identiy

        Returns number

  Returns Promise<{ done: any }>

  a promise resolves to a object (with a done field) when the request can be issued without queueing, resolves to null if the request has been cancelled (by the callback return less than 0). In this case the application should not issue the request
