/**
 * A class that represents the definition of a program that polls through consecutive requests
 * until it reaches a state of completion.
 *
 * A poller can be executed manually, by polling request by request by calling to the `poll()` method repeatedly, until its operation is completed.
 * It also provides a way to wait until the operation completes, by calling `pollUntilDone()` and waiting until the operation finishes.
 * Pollers can also request the cancellation of the ongoing process to whom is providing the underlying long running operation.
 *
 * ```ts
 * const poller = new MyPoller();
 *
 * // Polling just once:
 * await poller.poll();
 *
 * // We can try to cancel the request here, by calling:
 * //
 * //     await poller.cancelOperation();
 * //
 *
 * // Getting the final result:
 * const result = await poller.pollUntilDone();
 * ```
 *
 * The Poller is defined by two types, a type representing the state of the poller, which
 * must include a basic set of properties from `PollOperationState<TResult>`,
 * and a return type defined by `TResult`, which can be anything.
 *
 * The Poller class implements the `PollerLike` interface, which allows poller implementations to avoid having
 * to export the Poller's class directly, and instead only export the already instantiated poller with the PollerLike type.
 *
 * ```ts
 * class Client {
 *   public async makePoller: PollerLike<MyOperationState, MyResult> {
 *     const poller = new MyPoller({});
 *     // It might be preferred to return the poller after the first request is made,
 *     // so that some information can be obtained right away.
 *     await poller.poll();
 *     return poller;
 *   }
 * }
 *
 * const poller: PollerLike<MyOperationState, MyResult> = myClient.makePoller();
 * ```
 *
 * A poller can be created through its constructor, then it can be polled until it's completed.
 * At any point in time, the state of the poller can be obtained without delay through the getOperationState method.
 * At any point in time, the intermediate forms of the result type can be requested without delay.
 * Once the underlying operation is marked as completed, the poller will stop and the final value will be returned.
 *
 * ```ts
 * const poller = myClient.makePoller();
 * const state: MyOperationState = poller.getOperationState();
 *
 * // The intermediate result can be obtained at any time.
 * const result: MyResult | undefined = poller.getResult();
 *
 * // The final result can only be obtained after the poller finishes.
 * const result: MyResult = await poller.pollUntilDone();
 * ```
 *

     * A poller needs to be initialized by passing in at least the basic properties of the `PollOperation<TState, TResult>`.
     *
     * When writing an implementation of a Poller, this implementation needs to deal with the initialization
     * of any custom state beyond the basic definition of the poller. The basic poller assumes that the poller's
     * operation has already been defined, at least its basic properties. The code below shows how to approach
     * the definition of the constructor of a new custom poller.
     *
     * ```ts
     * export class MyPoller extends Poller<MyOperationState, string> {
     *   constructor({
     *     // Anything you might need outside of the basics
     *   }) {
     *     let state: MyOperationState = {
     *       privateProperty: private,
     *       publicProperty: public,
     *     };
     *
     *     const operation = {
     *       state,
     *       update,
     *       cancel,
     *       toString
     *     }
     *
     *     // Sending the operation to the parent's constructor.
     *     super(operation);
     *
     *     // You can assign more local properties here.
     *   }
     * }
     * ```
     *
     * Inside of this constructor, a new promise is created. This will be used to
     * tell the user when the poller finishes (see `pollUntilDone()`). The promise's
     * resolve and reject methods are also used internally to control when to resolve
     * or reject anyone waiting for the poller to finish.
     *
     * The constructor of a custom implementation of a poller is where any serialized version of
     * a previous poller's operation should be deserialized into the operation sent to the
     * base constructor. For example:
     *
     * ```ts
     * export class MyPoller extends Poller<MyOperationState, string> {
     *   constructor(
     *     baseOperation: string | undefined
     *   ) {
     *     let state: MyOperationState = {};
     *     if (baseOperation) {
     *       state = {
     *         ...JSON.parse(baseOperation).state,
     *         ...state
     *       };
     *     }
     *     const operation = {
     *       state,
     *       // ...
     *     }
     *     super(operation);
     *   }

     * Even though TState will be the same type inside any of the methods of any extension of the Poller class,
     * implementations of the pollers can customize what's shared with the public by writing their own
     * version of the `getOperationState` method, and by defining two types, one representing the internal state of the poller
     * and a public type representing a safe to share subset of the properties of the internal state.
     * Their definition of getOperationState can then return their public type.
     *
     * Example:
     *
     * ```ts
     * // Let's say we have our poller's operation state defined as:
     * interface MyOperationState extends PollOperationState<ResultType> {
     *   privateProperty?: string;
     *   publicProperty?: string;
     * }
     *
     * // To allow us to have a true separation of public and private state, we have to define another interface:
     * interface PublicState extends PollOperationState<ResultType> {
     *   publicProperty?: string;
     * }
     *
     * // Then, we define our Poller as follows:
     * export class MyPoller extends Poller<MyOperationState, ResultType> {
     *   // ... More content is needed here ...
     *
     *   public getOperationState(): PublicState {
     *     const state: PublicState = this.operation.state;
     *     return {
     *       // Properties from PollOperationState<TResult>
     *       isStarted: state.isStarted,
     *       isCompleted: state.isCompleted,
     *       isCancelled: state.isCancelled,
     *       error: state.error,
     *       result: state.result,
     *
     *       // The only other property needed by PublicState.
     *       publicProperty: state.publicProperty
     *     }
     *   }
     * }
     * ```
     *

     * `../test/utils/testPoller.ts`
     * and look for the getOperationState implementation.
