Method Detail
__construct() ¶ public
__construct(array $config = [])
Constructor.
Parameters
-
array
$config optional Array of config.
_configDelete() ¶ protected
_configDelete(string $key): void
Delete a single config key
Parameters
-
string
$key Key to delete.
Returns
void
Throws
Cake\Core\Exception\Exception
if attempting to clobber existing config
_configRead() ¶ protected
_configRead(string|null $key): mixed
Read a config variable
Parameters
-
string|null
$key Key to read.
Returns
mixed
_configWrite() ¶ protected
_configWrite(string|array $key, mixed $value, bool|string $merge = false): void
Write a config variable
Parameters
-
string|array
$key Key to write to.
-
mixed
$value Value to write.
-
bool|string
$merge optional True to merge recursively, 'shallow' for simple merge, false to overwrite, defaults to false.
Returns
void
Throws
Cake\Core\Exception\Exception
if attempting to clobber existing config
_deliverAsset() ¶ protected
_deliverAsset(Cake\Network\Request $request, Cake\Network\Response $response, string $assetFile, string $ext): Cake\Network\Response
Sends an asset file to the client
Parameters
-
Cake\Network\Request
$request The request object to use.
-
Cake\Network\Response
$response The response object to use.
-
string
$assetFile Path to the asset file in the file system
-
string
$ext The extension of the file to determine its mime type
Returns
Cake\Network\Response
_getAssetFile() ¶ protected
_getAssetFile(string $url): string
Builds asset file path based off url
Parameters
-
string
$url Asset URL
Returns
string
afterDispatch() ¶ public
afterDispatch(Cake\Event\Event $event): void
Method called after the controller served a request and generated a response. It is possible to alter the response object at this point as it is not sent to the client yet.
If false is returned, the event will be stopped and no more listeners will be notified.
Alternatively you can call $event->stopPropagation()
to achieve the same result.
Parameters
-
Cake\Event\Event
$event container object having the
request
andresponse
keys in the data property.
Returns
void
beforeDispatch() ¶ public
beforeDispatch(Cake\Event\Event $event): Cake\Network\Response|null
Checks if a requested asset exists and sends it to the browser
If a Cake\Network\Response object instance is returned, it will be served at the end of the event cycle, not calling any controller as a result. This will also have the effect of not calling the after event in the dispatcher.
If false is returned, the event will be stopped and no more listeners will be notified.
Alternatively you can call $event->stopPropagation()
to achieve the same result.
Parameters
-
Cake\Event\Event
$event Event containing the request and response object
Returns
Cake\Network\Response|null
Throws
Cake\Network\Exception\NotFoundException
When asset not found
config() ¶ public
config(string|array|null $key = null, mixed|null $value = null, bool $merge = true): mixed
Usage
