Parameters

string	$key	The key
mixed	$value	The value

Exceptions

InvalidArgumentException

mixed getOption(string $key)

Gets an option value.

Parameters

string

$key

The key

Return Value

The value

Exceptions

InvalidArgumentException

RouteCollection getRouteCollection()

Gets the RouteCollection instance associated with this Router.

Return Value

RouteCollection

A RouteCollection instance

setContext(RequestContext $context)

Sets the request context.

Parameters

RequestContext

$context

RequestContext getContext()

Gets the request context.

Return Value

RequestContext

The context

setConfigCacheFactory(ConfigCacheFactoryInterface $configCacheFactory)

Sets the ConfigCache factory to use.

Parameters

ConfigCacheFactoryInterface

$configCacheFactory

string generate(string $name, mixed $parameters = array(), int $referenceType = self::ABSOLUTE_PATH)

Generates a URL or path for a specific route based on the given parameters.

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.

Parameters

string	$name	The name of the route
mixed	$parameters	An array of parameters
int	$referenceType	The type of reference to be generated (one of the constants)

Return Value

string

The generated URL

Exceptions

RouteNotFoundException	If the named route doesn't exist
MissingMandatoryParametersException	When some parameters are missing that are mandatory for the route
InvalidParameterException	When a parameter value for a placeholder is not correct because it does not match the requirement

array match(string $pathinfo)

Tries to match a URL path with a set of routes.

If the matcher can not find information, it must throw one of the exceptions documented below.

Parameters

$pathinfo

The path info to be parsed (raw format, i.e. not urldecoded)

Return Value

array

An array of parameters

Exceptions

NoConfigurationException	If no routing configuration could be found
ResourceNotFoundException	If the resource could not be found
MethodNotAllowedException	If the resource was found but the request method is not allowed

array matchRequest(Request $request)

Tries to match a request with a set of routes.

If the matcher can not find information, it must throw one of the exceptions documented below.

Parameters

Request

$request

Return Value

array

An array of parameters

Exceptions

NoConfigurationException	If no routing configuration could be found
ResourceNotFoundException	If no matching resource could be found
MethodNotAllowedException	If a matching resource was found but the request method is not allowed

UrlMatcherInterface getMatcher()

Return Value

UrlMatcherInterface

A UrlMatcherInterface instance

UrlGeneratorInterface getGenerator()

Gets the UrlGenerator instance associated with this Router.

Return Value

UrlGeneratorInterface

A UrlGeneratorInterface instance

addExpressionLanguageProvider(ExpressionFunctionProviderInterface $provider)

Parameters

ExpressionFunctionProviderInterface

$provider

protected GeneratorDumperInterface getGeneratorDumperInstance()

Return Value

GeneratorDumperInterface

protected MatcherDumperInterface getMatcherDumperInstance()

warmUp(string $cacheDir)

Warms up the cache.

Parameters

string

$cacheDir

The cache directory

static array getSubscribedServices()

Returns an array of service types required by such instances, optionally keyed by the service names used internally.

For mandatory dependencies:

• array('logger' => 'Psr\Log\LoggerInterface') means the objects use the "logger" name internally to fetch a service which must implement Psr\Log\LoggerInterface.
• array('Psr\Log\LoggerInterface') is a shortcut for
• array('Psr\Log\LoggerInterface' => 'Psr\Log\LoggerInterface')

otherwise:

• array('logger' => '?Psr\Log\LoggerInterface') denotes an optional dependency
• array('?Psr\Log\LoggerInterface') is a shortcut for
• array('Psr\Log\LoggerInterface' => '?Psr\Log\LoggerInterface')

Return Value

array

The required service types, optionally keyed by service names
