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

32 interface UrlGeneratorInterface extends RequestContextAwareInterface
35 * Generates an absolute URL, e.g. "http://example.com/dir/file".
37 const ABSOLUTE_URL = 0;
40 * Generates an absolute path, e.g. "/dir/file".
42 const ABSOLUTE_PATH = 1;
45 * Generates a relative path based on the current request path, e.g. "../parent-file".
47 * @see UrlGenerator::getRelativePath()
49 const RELATIVE_PATH = 2;
52 * Generates a network path, e.g. "//example.com/dir/file".
53 * Such reference reuses the current scheme but specifies the host.
55 const NETWORK_PATH = 3;
58 * Generates a URL or path for a specific route based on the given parameters.
60 * Parameters that reference placeholders in the route pattern will substitute them in the
61 * path or host. Extra params are added as query string to the URL.
63 * When the passed reference type cannot be generated for the route because it requires a different
64 * host or scheme than the current one, the method will return a more comprehensive reference
65 * that includes the required params. For example, when you call this method with $referenceType = ABSOLUTE_PATH
66 * but the route requires the https scheme whereas the current scheme is http, it will instead return an
67 * ABSOLUTE_URL with the https scheme and the current host. This makes sure the generated URL matches
68 * the route in any case.
70 * If there is no route with the given name, the generator must throw the RouteNotFoundException.
72 * @param string $name The name of the route
73 * @param mixed $parameters An array of parameters
74 * @param int $referenceType The type of reference to be generated (one of the constants)
76 * @return string The generated URL
78 * @throws RouteNotFoundException If the named route doesn't exist
79 * @throws MissingMandatoryParametersException When some parameters are missing that are mandatory for the route
80 * @throws InvalidParameterException When a parameter value for a placeholder is not correct because
81 * it does not match the requirement
