__construct(string $environment, bool $debug)

Parameters

string	$environment
bool	$debug

__clone()

boot()

Boots the current kernel.

reboot(string|null $warmupDir)

Reboots a kernel.

The getCacheDir() method of a rebootable kernel should not be called while building the container. Use the %kernel.cache_dir% parameter instead.

Parameters

string|null

$warmupDir

pass null to reboot in the regular cache directory

terminate(Request $request, Response $response)

Terminates a request/response cycle.

Should be called after sending the response and before shutting down the kernel.

Parameters

Request	$request
Response	$response

shutdown()

Shutdowns the kernel.

This method is mainly useful when doing functional testing.

Response handle(Request $request, int $type = HttpKernelInterface::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::MASTER_REQUEST or HttpKernelInterface::SUB_REQUEST)
bool	$catch	Whether to catch exceptions or not

Return Value

Response

A Response instance

Exceptions

Exception

When an Exception occurs during processing

protected HttpKernel getHttpKernel()

Gets a HTTP kernel from the container.

Return Value

HttpKernel

BundleInterface[] getBundles()

Gets the registered bundle instances.

Return Value

BundleInterface[]

An array of registered bundle instances

BundleInterface getBundle(string $name)

Returns a bundle.

Parameters

string

$name

Bundle name

Return Value

BundleInterface

A BundleInterface instance

Exceptions

InvalidArgumentException

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

Returns the file path for a given bundle 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()

Gets the name of the kernel.

Return Value

string

The kernel name

string getEnvironment()

Gets the environment.

Return Value

string

bool isDebug()

Return Value

string

The Kernel root dir

string getProjectDir()

Gets the application root dir (path of the project's composer file).

Return Value

string

ContainerInterface|null getContainer()

Gets the current container.

Return Value
