/**
 * @description
 * A object which defines the configurable arguments which may be passed to
 * functions in those classes which implement the {@link ConfigurableOperationDef} interface.
 *
 * ## Data types
 * Each argument has a data type, which must be one of {@link ConfigArgType}.
 *
 * @example
 * ```ts
 * {
 *   apiKey: { type: 'string' },
 *   maxRetries: { type: 'int' },
 *   logErrors: { type: 'boolean' },
 * }
 * ```
 *
 * ## Lists
 * Setting the `list` property to `true` will make the argument into an array of the specified
 * data type. For example, if you want to store an array of strings:
 *
 * @example
 * ```ts
 * {
 *   aliases: {
 *     type: 'string',
 *     list: true,
 *   },
 * }
 *```
 * In the Admin UI, this will be rendered as an orderable list of string inputs.
 *
 * ## UI Component
 * The `ui` field allows you to specify a specific input component to be used in the Admin UI.
 * When not set, a default input component is used appropriate to the data type.
 *
 * @example
 * ```ts
 * {
 *   operator: {
 *     type: 'string',
 *     ui: {
 *       component: 'select-form-input',
 *       options: [
 *         { value: 'startsWith' },
 *         { value: 'endsWith' },
 *         { value: 'contains' },
 *         { value: 'doesNotContain' },
 *       ],
 *     },
 *   },
 *   secretKey: {
 *     type: 'string',
 *     ui: { component: 'password-form-input' },
 *   },
 * }
 * ```
 * The available components as well as their configuration options can be found in the {@link DefaultFormConfigHash} docs.
 * Custom UI components may also be defined via an Admin UI extension using the `registerFormInputComponent()` function
 * which is exported from `@vendure/admin-ui/core`.

/**
 * @description
 * A ConfigurableOperationDef is a special type of object used extensively by Vendure to define
 * code blocks which have arguments which are configurable at run-time by the administrator.
 *
 * This is the mechanism used by:
 *
 * * {@link CollectionFilter}
 * * {@link PaymentMethodHandler}
 * * {@link PromotionAction}
 * * {@link PromotionCondition}
 * * {@link ShippingCalculator}
 * * {@link ShippingEligibilityChecker}
 *
 * Any class which extends ConfigurableOperationDef works in the same way: it takes a
 * config object as the constructor argument. That config object extends the {@link ConfigurableOperationDefOptions}
 * interface and typically adds some kind of business logic function to it.
 *
 * For example, in the case of `ShippingEligibilityChecker`,
 * it adds the `check()` function to the config object which defines the logic for checking whether an Order is eligible
 * for a particular ShippingMethod.
 *
 * ## The `args` property
 *
 * The key feature of the ConfigurableOperationDef is the `args` property. This is where we define those
 * arguments that are exposed via the Admin UI as data input components. This allows their values to
 * be set at run-time by the Administrator. Those values can then be accessed in the business logic
 * of the operation.
 *
 * The data type of the args can be one of {@link ConfigArgType}, and the configuration is further explained in
 * the docs of {@link ConfigArgs}.
 *
 * ## Dependency Injection
 * If your business logic relies on injectable providers, such as the `TransactionalConnection` object, or any of the
 * internal Vendure services or those defined in a plugin, you can inject them by using the config object's
 * `init()` method, which exposes the {@link Injector}.
 *
 * Here's an example of a ShippingCalculator that injects a service which has been defined in a plugin:
 *
 * @example
 * ```ts
 * import { Injector, ShippingCalculator } from '\@vendure/core';
 * import { ShippingRatesService } from './shipping-rates.service';
 *
 * // We keep reference to our injected service by keeping it
 * // in the top-level scope of the file.
 * let shippingRatesService: ShippingRatesService;
 *
 * export const customShippingCalculator = new ShippingCalculator({
 *   code: 'custom-shipping-calculator',
 *   description: [],
 *   args: {},
 *
 *   init(injector: Injector) {
 *     // The init function is called during bootstrap, and allows
 *     // us to inject any providers we need.
 *     shippingRatesService = injector.get(ShippingRatesService);
 *   },
 *
 *   calculate: async (order, args) => {
 *     // We can now use the injected provider in the business logic.
 *     const { price, priceWithTax } = await shippingRatesService.getRate({
 *       destination: order.shippingAddress,
 *       contents: order.lines,
 *     });
 *
 *     return {
 *       price,
 *       priceWithTax,
 *     };
 *   },
 * });
 * ```
