/**
* UrlGeneratorInterface is the interface that all URL generator classes must implement.
*
* The constants in this interface define the different types of resource references that
* are declared in RFC 3986: http://tools.ietf.org/html/rfc3986
* We are using the term "URL" instead of "URI" as this is more common in web applications
* and we do not need to distinguish them as the difference is mostly semantical and
* less technical. Generating URIs, i.e. representation-independent resource identifiers,
* is also possible.

* Parameters that reference placeholders in the route pattern will substitute them in the
* path or host. Extra params are added as query string to the URL.
*
* When the passed reference type cannot be generated for the route because it requires a different
* host or scheme than the current one, the method will return a more comprehensive reference
* that includes the required params. For example, when you call this method with $referenceType = ABSOLUTE_PATH
* but the route requires the https scheme whereas the current scheme is http, it will instead return an
* ABSOLUTE_URL with the https scheme and the current host. This makes sure the generated URL matches
* the route in any case.
*
* If there is no route with the given name, the generator must throw the RouteNotFoundException.
*
* The special parameter _fragment will be used as the document fragment suffixed to the final URL.
*
* @throws RouteNotFoundException If the named route doesn't exist
* @throws MissingMandatoryParametersException When some parameters are missing that are mandatory for the route
* @throws InvalidParameterException When a parameter value for a placeholder is not correct because
* it does not match the requirement
