__construct() ¶ public
__construct(array<string, mixed> $config = [])__construct method
Parameters
-
array<string, mixed>$config optional Configuration array
_configDelete() ¶ protected
_configDelete(string $key): voidDeletes a single config key.
Parameters
-
string$key Key to delete.
Returns
voidThrows
Cake\Core\Exception\CakeExceptionif attempting to clobber existing config
_configRead() ¶ protected
_configRead(string|null $key): mixedReads a config key.
Parameters
-
string|null$key Key to read.
Returns
mixed_configWrite() ¶ protected
_configWrite(array<string, mixed>|string $key, mixed $value, string|bool $merge = false): voidWrites a config key.
Parameters
-
array<string, mixed>|string$key Key to write to.
-

-
string|bool$merge optional True to merge recursively, 'shallow' for simple merge, false to overwrite, defaults to false.
Returns
voidThrows
Cake\Core\Exception\CakeExceptionif attempting to clobber existing config
_format() ¶ protected
_format(string $message, array $context = []): stringFormats the message to be logged.
The context can optionally be used by log engines to interpolate variables or add additional info to the logged message.
Parameters

Returns
stringalert() ¶ public
alert(stringStringable $message, mixed[] $context = []): voidAction must be taken immediately.

$this->configShallow('some.nested.key', $value);Updating multiple config settings at the same time:
$this->configShallow(['one' => 'value', 'another' => 'value']);Parameters
-
array<string, mixed>|string$key The key to set, or a complete array of configs.
-
mixed|null$value optional The value to set.
