lithium\core\Object- The `'type'` key is the content type that will be rendered by default, unless another is explicitly specified (defaults to `'html'`). - The `'data'` key contains an associative array of variables to be sent to the view, including any variables created in `set()`, or if an action returns any variables (as an associative array). - When an action is invoked, it will by default attempt to render a response, set the `'auto'` key to `false` to prevent this behavior. - If you manually call `render()` within an action, the `'hasRendered'` key stores this state, so that responses are not rendered multiple times, either manually or automatically. - The `'layout'` key specifies the name of the layout to be used (defaults to `'default'`). Typically, layout files are looked up as `<app-path>/views/layouts/<layout-name>.<type>.php`. Based on the default settings, the actual path would be `path-to-app/views/layouts/default.html.php`. - Though typically introspected from the action that is executed, the `'template'` key can be manually specified. This sets the template to be rendered, and is looked up (by default) as `<app-path>/views/<controller>/<action>.<type>.php`, i.e.: `path-to-app/views/posts/index.html.php`. - To enable automatic content-type negotiation (i.e. determining the content type of the response based on the value of the [HTTP Accept header](http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html)), set the `'negotiate'` flag to `true`. Otherwise, the response will only be based on the `type` parameter of the request object (defaulting to `'html'` if no type is present in the `Request` parameters). Keep in mind that most of these settings may be passed to `Controller::render()` as well. To change how these settings operate (i.e. template paths, default render settings for individual media types), see the `Media` class.
