Details
__construct(bool $magicCall = false, bool $throwExceptionOnInvalidIndex = false, CacheItemPoolInterface $cacheItemPool = null)
Should not be used by application code. Use {@link PropertyAccess::createPropertyAccessor()} instead.
mixed
getValue(object|array $objectOrArray, string|PropertyPathInterface $propertyPath)
Returns the value at the end of the property path of the object graph.
Example:
use Symfony\Component\PropertyAccess\PropertyAccess;
$propertyAccessor = PropertyAccess::createPropertyAccessor();
echo $propertyAccessor->getValue($object, 'child.name);
// equals echo $object->getChild()->getName();
This method first tries to find a public getter for each property in the path. The name of the getter must be the camel-cased property name prefixed with "get", "is", or "has".
If the getter does not exist, this method tries to find a public property. The value of the property is then returned.
If none of them are found, an exception is thrown.
setValue(object|array $objectOrArray, string|PropertyPathInterface $propertyPath, mixed $value)
Sets the value at the end of the property path of the object graph.
Example:
use Symfony\Component\PropertyAccess\PropertyAccess;
$propertyAccessor = PropertyAccess::createPropertyAccessor();
echo $propertyAccessor->setValue($object, 'child.name', 'Fabien');
// equals echo $object->getChild()->setName('Fabien');
This method first tries to find a public setter for each property in the path. The name of the setter must be the camel-cased property name prefixed with "set".
If the setter does not exist, this method tries to find a public property. The value of the property is then changed.
If neither is found, an exception is thrown.
bool
isReadable(object|array $objectOrArray, string|PropertyPathInterface $propertyPath)
Returns whether a property path can be read from an object graph.
Whenever this method returns true, {@link getValue()} is guaranteed not to throw an exception when called with the same arguments.
bool
isWritable(object|array $objectOrArray, string|PropertyPathInterface $propertyPath)
Returns whether a value can be written at a given property path.
Whenever this method returns true, {@link setValue()} is guaranteed not to throw an exception when called with the same arguments.
static AdapterInterface
createCache(string $namespace, int $defaultLifetime, string $version, LoggerInterface $logger = null)
Creates the APCu adapter if applicable.
