Methods
__construct()
public
__construct(Profiler $profiler, RequestStack $requestStack[, RequestMatcherInterface|null $matcher = null ][, bool $onlyException = false ][, bool $onlyMainRequests = false ][, string|null $collectParameter = null ]) : mixed
Parameters
- $profiler : Profiler
- $requestStack : RequestStack
- $matcher : RequestMatcherInterface|null = null
- $onlyException : bool = false
-
True if the profiler only collects data when an exception occurs, false otherwise
- $onlyMainRequests : bool = false
-
True if the profiler only collects data when the request is the main request, false otherwise
- $collectParameter : string|null = null
Return values
mixed —getSubscribedEvents()
Returns an array of event names this subscriber wants to listen to.
public
static getSubscribedEvents() : array<string, string|array{0: string, 1: int}|list>
The array keys are event names and the value can be:
- The method name to call (priority defaults to 0)
- An array composed of the method name to call and the priority
- An array of arrays composed of the method names to call and respective priorities, or 0 if unset
For instance:
- ['eventName' => 'methodName']
- ['eventName' => ['methodName', $priority]]
- ['eventName' => [['methodName1', $priority], ['methodName2']]]
The code must not depend on runtime state as it will only be called at compile time. All logic depending on runtime state must be put into the individual methods handling the events.
Return values
array<string, string|array{0: string, 1: int}|listonKernelException()
Handles the onKernelException event.
public
onKernelException(ExceptionEvent $event) : mixed
Parameters
- $event : ExceptionEvent
Return values
mixed —onKernelResponse()
Handles the onKernelResponse event.
public
onKernelResponse(ResponseEvent $event) : mixed
Parameters
- $event : ResponseEvent
Return values
mixed —onKernelTerminate()
public
onKernelTerminate(TerminateEvent $event) : mixed
Parameters
- $event : TerminateEvent
