which does
a recursive merge for nested keys, this method does a simple merge.
Setting a specific value:
$this->configShallow('key', $value);
Setting a nested value:
$this->configShallow('some.nested.key', $value);
Updating multiple config settings at the same time:
$this->configShallow(['one' => 'value', 'another' => 'value']);

array<string, mixed>|string
$key The key to set, or a complete array of configs.
-
mixed|null
$value optional The value to set.
Returns
$this
getConfig() ¶ public
getConfig(string|null $key = null, mixed $default = null): mixed
Returns the config.
Usage
Reading the whole config:
$this->getConfig();
Reading a specific value:
$this->getConfig('key');
Reading a nested value:
$this->getConfig('some.nested.key');
Reading with default value:
$this->getConfig('some-key', 'default-value');
Parameters
-
string|null
$key optional The key to get or null for the whole config.
-
mixed
$default optional The return value when the key does not exist.
Returns
mixed
getConfigOrFail() ¶ public
getConfigOrFail(string $key): mixed
Returns the config for this specific key.
The config value for this key must exist, it can never be null.
Parameters
-
string
$key The key to get.
Returns
mixed
Throws
InvalidArgumentException
handleEvent() ¶ public
handleEvent(Cake\Event\EventInterface<Cake\ORM\Table> $event, Cake\Datasource\EntityInterface $entity): void
There is only one event handler, it can be configured to be called for any event
Parameters
-
Cake\Event\EventInterface<Cake\ORM\Table>
$event Event instance.
-
Cake\Datasource\EntityInterface
$entity Entity instance.
Returns
void
Throws
UnexpectedValueException
if a field's when value is misdefined
UnexpectedValueException
When the value for an event is not 'always', 'new' or 'existing'
implementedEvents() ¶ public
implementedEvents(): array<string, mixed>
implementedEvents
The implemented events of this behavior depend on configuration
Returns
array<string, mixed>
implementedFinders() ¶ public
implementedFinders(): array
implementedFinders
Provides an alias->methodname map of which finders a behavior implements. Example:
[
'this' => 'findThis',
'alias' => 'findMethodName'
]
With the above example, a call to $table->find('this')
will call $behavior->findThis()
and a call to $table->find('alias')
will call $behavior->findMethodName()
It is recommended, though not required, to define implementedFinders in the config property of child classes such that it is not necessary to use reflections to derive the available method list. See core behaviors for examples
Returns
array
Throws
ReflectionException
implementedMethods() ¶ public
implementedMethods(): array
implementedMethods
Provides an alias->methodname map of which methods a behavior implements. Example:
[
'method' => 'method',
'aliasedMethod' => 'somethingElse'
]
With the above example, a call to $table->method()
will call $behavior->method()
and a call to $table->aliasedMethod()
will call $behavior->somethingElse()
It is recommended, though not required, to define implementedFinders in the config property of child classes such that it is not necessary to use reflections to derive the available method list. See core behaviors for examples
Returns
array
Throws
ReflectionException
initialize() ¶ public
initialize(array<string, mixed> $config): void
Initialize hook
If events are specified - do not merge them with existing events, overwrite the events to listen on
Parameters
-

Returns
void
setConfig() ¶ public
setConfig(array<string, mixed>|string $key, mixed|null $value = null, bool $merge = true): $this
Sets the config.
Usage
Setting a specific value:
$this->setConfig('key', $value);

array<string, mixed>|string
$key The key to set, or a complete array of configs.
-
mixed|null
$value optional The value to set.

bool
$_defaultConfig ¶ protected

These are merged with user-provided config when the behavior is used.
events - an event-name keyed array of which fields to update, and when, for a given event possible values for when a field will be updated are "always", "new" or "existing", to set the field value always, only when a new record or only when an existing record.
refreshTimestamp - if true (the default) the timestamp used will be the current time when the code is executed, to set to an explicit date time value - set refreshTimetamp to false and call setTimestamp() on the behavior class before use.
