Regardless of the value, when calling this function on a parameter, if that parameter has a callback function attached to it, that callback function will be called. For example, if the parameter is a button the button will be pressed.

In threaded mode, this is an async call!

This API will invoke the cooking thread if threading is enabled. This means it will return immediately. Use the status and cooking count APIs under DIAGNOSTICS to get a sense of the progress. All other API calls will block until the cook operation has finished.

Also note that the cook result won’t be of type hapi.statusType.CallResult like all calls (including this one). Whenever the threading cook is done it will fill the cook result which is queried using hapi.statusType.CookResult.
