KernelInterface

Response handle(Request $request, int $type = self::MASTER_REQUEST, bool $catch = true)

Handles a Request to convert it to a Response.

When $catch is true, the implementation must catch all exceptions and do its best to convert them to a Response instance.

Parameters

Request	$request	A Request instance
int	$type	The type of the request (one of HttpKernelInterface::MASTERREQUEST or HttpKernelInterface::SUBREQUEST)
bool	$catch	Whether to catch exceptions or not

Return Value

Response

A Response instance

Exceptions

Exception

When an Exception occurs during processing

BundleInterface[] registerBundles()

Returns an array of bundles to register.

Return Value

BundleInterface[]

An array of bundle instances

registerContainerConfiguration(LoaderInterface $loader)

Loads the container configuration.

Parameters

LoaderInterface

$loader

boot()

Boots the current kernel.

shutdown()

Shutdowns the kernel.

This method is mainly useful when doing functional testing.

BundleInterface[] getBundles()

Gets the registered bundle instances.

Return Value

BundleInterface[]

An array of registered bundle instances

BundleInterface|BundleInterface[] getBundle(string $name, bool $first = true)

Returns a bundle and optionally its descendants by its name.

The second argument is deprecated as of 3.4 and will be removed in 4.0. This method will always return an instance of BundleInterface in 4.0.

Parameters

string	$name	Bundle name
bool	$first	Whether to return the first bundle only or together with its descendants

Return Value

BundleInterface|BundleInterface[]

A BundleInterface instance or an array of BundleInterface instances if $first is false

Exceptions

InvalidArgumentException

when the bundle is not enabled

string|array locateResource(string $name, string $dir = null, bool $first = true)

Returns the file path for a given resource.

A Resource can be a file or a directory.

The resource name must follow the following pattern:

"@BundleName/path/to/a/file.something"

where BundleName is the name of the bundle and the remaining part is the relative path in the bundle.

If $dir is passed, and the first segment of the path is "Resources", this method will look for a file named:

$dir/<BundleName>/path/without/Resources

before looking in the bundle resource folder.

Parameters

string	$name	A resource name to locate
string	$dir	A directory where to look for the resource first
bool	$first	Whether to return the first path or paths for all matching bundles

Return Value

string|array

The absolute path of the resource or an array if $first is false

Exceptions

InvalidArgumentException	if the file cannot be found or the name is not valid
RuntimeException	if the name contains invalid/unsafe characters

string getName()

string getEnvironment()

Return Value

string

The Kernel root dir

ContainerInterface getContainer()

Gets the current container.

Return Value

string getCacheDir()

Gets the cache directory.

Return Value

string

The cache directory

string getLogDir()

Gets the log directory.

Return Value

string
