Details

__construct(Connection $connection, StateInterface $state, CurrentPathStack $current_path, CacheBackendInterface $cache_backend, InboundPathProcessorInterface $path_processor, CacheTagsInvalidatorInterface $cache_tag_invalidator, string $table = 'router', LanguageManagerInterface $language_manager = NULL)

Constructs a new PathMatcher.

Parameters

Connection $connection

A database connection object.

StateInterface $state

The state.

CurrentPathStack $current_path

The current path.

CacheBackendInterface $cache_backend

The cache backend.

InboundPathProcessorInterface $path_processor

The path processor.

CacheTagsInvalidatorInterface $cache_tag_invalidator

The cache tag invalidator.

string $table

(Optional) The table in the database to use for matching. Defaults to 'router'

LanguageManagerInterface $language_manager

(Optional) The language manager.

RouteCollection getRouteCollectionForRequest(Request $request)

Finds routes that may potentially match the request.

This may return a mixed list of class instances, but all routes returned must extend the core symfony route. The classes may also implement RouteObjectInterface to link to a content document.

This method may not throw an exception based on implementation specific restrictions on the url. That case is considered a not found - returning an empty array. Exceptions are only used to abort the whole request in case something is seriously broken, like the storage backend being down.

Note that implementations may not implement an optimal matching algorithm, simply a reasonable first pass. That allows for potentially very large route sets to be filtered down to likely candidates, which may then be filtered in memory more completely.

Parameters

Request $request

A request against which to match

Return Value

RouteCollection

All Routes that could potentially match $request. Empty collection if nothing can match

Route getRouteByName(string $name)

Find the route using the provided route name.

Parameters

string $name

The route name to fetch

Return Value

Route

The Symfony route object.

Exceptions

RouteNotFoundException

preLoadRoutes(string[] $names)

Pre-load routes by their names using the provided list of names.

This method exists in order to allow performance optimizations. It allows pre-loading serialized routes that may latter be retrieved using ::getRoutesByName()

Parameters

string[] $names

Array of route names to load.

Route[] getRoutesByNames(array|null $names)

Find many routes by their names using the provided list of names.

Note that this method may not throw an exception if some of the routes are not found or are not actually Route instances. It will just return the list of those Route instances it found.

This method exists in order to allow performance optimizations. The simple implementation could be to just repeatedly call $this->getRouteByName() while catching and ignoring eventual exceptions.

If $names is null, this method SHOULD return a collection of all routes known to this provider. If there are many routes to be expected, usage of a lazy loading collection is recommended. A provider MAY only return a subset of routes to e.g. support paging or other concepts.

Parameters

array|null $names

The list of names to retrieve, In case of null, the provider will determine what routes to return

Return Value

Route[]

Iterable list with the keys being the names from the $names array

protected array getCandidateOutlines(array $parts)

Returns an array of path pattern outlines that could match the path parts.

Parameters

array $parts

The parts of the path for which we want candidates.

Return Value

array

An array of outlines that could match the specified path parts.

RouteCollection getRoutesByPattern(string $pattern)

Get all routes which match a certain pattern.

Parameters

string $pattern

The route pattern to search for (contains } as placeholders).

Return Value

RouteCollection

Returns a route collection of matching routes. The collection may be empty and will be sorted from highest to lowest fit (match of path parts) and then in ascending order by route name for routes with the same fit.

protected RouteCollection getRoutesByPath(string $path)

Get all routes which match a certain pattern.

Parameters

string $path

The route pattern to search for.

Return Value

RouteCollection

Returns a route collection of matching routes. The collection may be empty and will be sorted from highest to lowest fit (match of path parts) and then in ascending order by route name for routes with the same fit.

protected routeProviderRouteCompare(array $a, array $b)

Comparison function for usort on routes.

Parameters

array $a
array $b

Route[] getAllRoutes()

Returns all the routes on the system.

Usage of this method is discouraged for performance reasons. If possible, use RouteProviderInterface::getRoutesByNames() or RouteProviderInterface::getRoutesByPattern() instead.

Return Value

Route[]

An iterator of routes keyed by route name.

reset()

Resets the route provider object.

static getSubscribedEvents()
