    /**
     * Generate REST resource routes for the given controller(s).
     *
     * A quick way to generate a default routes to a set of REST resources (controller(s)).
     *
     * ### Usage
     *
     * Connect resource routes for an app controller:
     *
     * ```
     * $routes->resources('Posts');
     * ```
     *
     * Connect resource routes for the Comments controller in the
     * Comments plugin:
     *
     * ```
     * Router::plugin('Comments', function ($routes) {
     *   $routes->resources('Comments');
     * });
     * ```
     *
     * Plugins will create lowercase dasherized resource routes. e.g
     * `/comments/comments`
     *
     * Connect resource routes for the Articles controller in the
     * Admin prefix:
     *
     * ```
     * Router::prefix('Admin', function ($routes) {
     *   $routes->resources('Articles');
     * });
     * ```
     *
     * Prefixes will create lowercase dasherized resource routes. e.g
     * `/admin/posts`
     *
     * You can create nested resources by passing a callback in:
     *
     * ```
     * $routes->resources('Articles', function ($routes) {
     *   $routes->resources('Comments');
     * });
     * ```
     *
     * The above would generate both resource routes for `/articles`, and `/articles/{article_id}/comments`.
     * You can use the `map` option to connect additional resource methods:
     *
     * ```
     * $routes->resources('Articles', [
     *   'map' => ['deleteAll' => ['action' => 'deleteAll', 'method' => 'DELETE']]
     * ]);
     * ```
     *
     * In addition to the default routes, this would also connect a route for `/articles/delete_all`.
     * By default, the path segment will match the key name. You can use the 'path' key inside the resource
     * definition to customize the path name.
     *
     * You can use the `inflect` option to change how path segments are generated:
     *
     * ```
     * $routes->resources('PaymentTypes', ['inflect' => 'underscore']);
     * ```
     *
     * Will generate routes like `/payment-types` instead of `/payment_types`
     *
     * ### Options:
     *
     * - 'id' - The regular expression fragment to use when matching IDs. By default, matches
     *    integer values and UUIDs.
     * - 'inflect' - Choose the inflection method used on the resource name. Defaults to 'dasherize'.
     * - 'only' - Only connect the specific list of actions.
     * - 'actions' - Override the method names used for connecting actions.
     * - 'map' - Additional resource routes that should be connected. If you define 'only' and 'map',
     *   make sure that your mapped methods are also in the 'only' list.
     * - 'prefix' - Define a routing prefix for the resource controller. If the current scope
     *   defines a prefix, this prefix will be appended to it.
     * - 'connectOptions' - Custom options for connecting the routes.
     * - 'path' - Change the path so it doesn't match the resource name. E.g ArticlesController
     *   is available at `/posts`
     *
     * @param string $name A controller name to connect resource routes for.
     * @param \Closure|array $options Options to use when generating REST routes, or a callback.
     * @param \Closure|null $callback An optional callback to be executed in a nested scope. Nested
     *   scopes inherit the existing path and 'id' parameter.

     * parameters for a static route.
     *
     * ```
     * $routes->connect(
     *   '/{lang}/{controller}/{action}/{id}',
     *   [],
     *   ['id' => '[0-9]+', 'lang' => '[a-z]{3}']
     * );
     * ```
     *
     * Shows connecting a route with custom route parameters as well as
     * providing patterns for those parameters. Patterns for routing parameters
     * do not need capturing groups, as one will be added for each route params.
     *
     * $options offers several 'special' keys that have special meaning
     * in the $options array.
     *
     * - `routeClass` is used to extend and change how individual routes parse requests
     *   and handle reverse routing, via a custom routing class.
     *   Ex. `'routeClass' => 'SlugRoute'`
     * - `pass` is used to define which of the routed parameters should be shifted
     *   into the pass array. Adding a parameter to pass will remove it from the
     *   regular route array. Ex. `'pass' => ['slug']`.
     * -  `persist` is used to define which route parameters should be automatically
     *   included when generating new URLs. You can override persistent parameters
     *   by redefining them in a URL or remove them by setting the parameter to `false`.
     *   Ex. `'persist' => ['lang']`
     * - `multibytePattern` Set to true to enable multibyte pattern support in route
     *   parameter patterns.
     * - `_name` is used to define a specific name for routes. This can be used to optimize
     *   reverse routing lookups. If undefined a name will be generated for each
     *   connected route.
     * - `_ext` is an array of filename extensions that will be parsed out of the url if present.
     *   See {@link \Cake\Routing\RouteCollection::setExtensions()}.
     * - `_method` Only match requests with specific HTTP verbs.
     * - `_host` - Define the host name pattern if you want this route to only match
     *   specific host names. You can use `.*` and to create wildcard subdomains/hosts
     *   e.g. `*.example.com` matches all subdomains on `example.com`.
     * - '_port` - Define the port if you want this route to only match specific port number.
     *
     * Example of using the `_method` condition:
     *
     * ```
     * $routes->connect('/tasks', ['controller' => 'Tasks', 'action' => 'index', '_method' => 'GET']);
     * ```
     *
     * The above route will only be matched for GET requests. POST requests will fail to match this route.
     *
     * @param \Cake\Routing\Route\Route|string $route A string describing the template of the route
     * @param array|string $defaults An array describing the default route parameters.
     *   These parameters will be used by default and can supply routing parameters that are not dynamic. See above.
     * @param array<string, mixed> $options An array matching the named elements in the route to regular expressions which that
     *   element should match. Also contains additional parameters such as which routed parameters should be
     *   shifted into the passed arguments, supplying patterns for routing parameters and supplying the name of a
     *   custom routing class.

    /**
     * Generate REST resource routes for the given controller(s).
     *
     * A quick way to generate a default routes to a set of REST resources (controller(s)).
     *
     * ### Usage
     *
     * Connect resource routes for an app controller:
     *
     * ```
     * $routes->resources('Posts');
     * ```
     *
     * Connect resource routes for the Comments controller in the
     * Comments plugin:
     *
     * ```
     * Router::plugin('Comments', function ($routes) {
     *   $routes->resources('Comments');
     * });
     * ```
     *
     * Plugins will create lowercase dasherized resource routes. e.g
     * `/comments/comments`
     *
     * Connect resource routes for the Articles controller in the
     * Admin prefix:
     *
     * ```
     * Router::prefix('Admin', function ($routes) {
     *   $routes->resources('Articles');
     * });
     * ```
     *
     * Prefixes will create lowercase dasherized resource routes. e.g
     * `/admin/posts`
     *
     * You can create nested resources by passing a callback in:
     *
     * ```
     * $routes->resources('Articles', function ($routes) {
     *   $routes->resources('Comments');
     * });
     * ```
     *
     * The above would generate both resource routes for `/articles`, and `/articles/{article_id}/comments`.
     * You can use the `map` option to connect additional resource methods:
     *
     * ```
     * $routes->resources('Articles', [
     *   'map' => ['deleteAll' => ['action' => 'deleteAll', 'method' => 'DELETE']]
     * ]);
     * ```
     *
     * In addition to the default routes, this would also connect a route for `/articles/delete_all`.
     * By default, the path segment will match the key name. You can use the 'path' key inside the resource
     * definition to customize the path name.
     *
     * You can use the `inflect` option to change how path segments are generated:
     *
     * ```
     * $routes->resources('PaymentTypes', ['inflect' => 'underscore']);
     * ```
     *
     * Will generate routes like `/payment-types` instead of `/payment_types`
     *
     * ### Options:
     *
     * - 'id' - The regular expression fragment to use when matching IDs. By default, matches
     *    integer values and UUIDs.
     * - 'inflect' - Choose the inflection method used on the resource name. Defaults to 'dasherize'.
     * - 'only' - Only connect the specific list of actions.
     * - 'actions' - Override the method names used for connecting actions.
     * - 'map' - Additional resource routes that should be connected. If you define 'only' and 'map',
     *   make sure that your mapped methods are also in the 'only' list.
     * - 'prefix' - Define a routing prefix for the resource controller. If the current scope
     *   defines a prefix, this prefix will be appended to it.
     * - 'connectOptions' - Custom options for connecting the routes.
     * - 'path' - Change the path so it doesn't match the resource name. E.g ArticlesController
     *   is available at `/posts`
     *
     * @param string $name A controller name to connect resource routes for.
     * @param \Closure|array $options Options to use when generating REST routes, or a callback.
     * @param \Closure|null $callback An optional callback to be executed in a nested scope. Nested
     *   scopes inherit the existing path and 'id' parameter.

     * Routes are a way of connecting request URLs to objects in your application.

     * match requests to destinations.
     *
     * Examples:
     *
     * ```
     * $routes->connect('/{controller}/{action}/*');
     * ```
     *
     * The first parameter will be used as a controller name while the second is
     * used as the action name. The '/*' syntax makes this route greedy in that
     * it will match requests like `/posts/index` as well as requests
     * like `/posts/edit/1/foo/bar`.
     *
     * ```
     * $routes->connect('/home-page', ['controller' => 'Pages', 'action' => 'display', 'home']);
     * ```
     *
     * The above shows the use of route parameter defaults. And providing routing
     * parameters for a static route.
     *
     * ```
     * $routes->connect(
     *   '/{lang}/{controller}/{action}/{id}',
     *   [],
     *   ['id' => '[0-9]+', 'lang' => '[a-z]{3}']
     * );
     * ```
     *
     * Shows connecting a route with custom route parameters as well as
     * providing patterns for those parameters. Patterns for routing parameters
     * do not need capturing groups, as one will be added for each route params.
     *
     * $options offers several 'special' keys that have special meaning
     * in the $options array.
     *
     * - `routeClass` is used to extend and change how individual routes parse requests
     *   and handle reverse routing, via a custom routing class.
     *   Ex. `'routeClass' => 'SlugRoute'`
     * - `pass` is used to define which of the routed parameters should be shifted
     *   into the pass array. Adding a parameter to pass will remove it from the
     *   regular route array. Ex. `'pass' => ['slug']`.
     * -  `persist` is used to define which route parameters should be automatically
     *   included when generating new URLs. You can override persistent parameters
     *   by redefining them in a URL or remove them by setting the parameter to `false`.
     *   Ex. `'persist' => ['lang']`
     * - `multibytePattern` Set to true to enable multibyte pattern support in route
     *   parameter patterns.
     * - `_name` is used to define a specific name for routes. This can be used to optimize
     *   reverse routing lookups. If undefined a name will be generated for each
     *   connected route.
     * - `_ext` is an array of filename extensions that will be parsed out of the url if present.
     *   See {@link \Cake\Routing\RouteCollection::setExtensions()}.
     * - `_method` Only match requests with specific HTTP verbs.
     * - `_host` - Define the host name pattern if you want this route to only match
     *   specific host names. You can use `.*` and to create wildcard subdomains/hosts
     *   e.g. `*.example.com` matches all subdomains on `example.com`.
     * - '_port` - Define the port if you want this route to only match specific port number.
     *
     * Example of using the `_method` condition:
     *
     * ```
     * $routes->connect('/tasks', ['controller' => 'Tasks', 'action' => 'index', '_method' => 'GET']);
     * ```
     *
     * The above route will only be matched for GET requests. POST requests will fail to match this route.

     * Connects a new redirection Route in the router.
     *
     * Redirection routes are different from normal routes as they perform an actual
     * header redirection if a match is found. The redirection can occur within your
     * application or redirect to an outside location.
     *
     * Examples:
     *
     * ```
     * $routes->redirect('/home/*', ['controller' => 'Posts', 'action' => 'view']);
     * ```
     *
     * Redirects /home/* to /posts/view and passes the parameters to /posts/view. Using an array as the
     * redirect destination allows you to use other routes to define where a URL string should be redirected to.
     *
     * ```
     * $routes->redirect('/posts/*', 'http://google.com', ['status' => 302]);
     * ```
     *
     * Redirects /posts/* to http://google.com with a HTTP status of 302
     *

     * - `persist` Passes the params to the redirected route, if it can. This is useful with greedy routes,
     *   routes that end in `*` are greedy. As you can remap URLs and not lose any passed args.
     *
     * @param string $route A string describing the template of the route
     * @param array|string $url A URL to redirect to. Can be a string or a Cake array-based URL
     * @param array<string, mixed> $options An array matching the named elements in the route to regular expressions which that
     *   element should match. Also contains additional parameters such as which routed parameters should be
     *   shifted into the passed arguments. As well as supplying patterns for routing parameters.
