Should not be used by application code. Use {@link PropertyAccess::createPropertyAccessor()} instead.

  • param int $magicMethodsFlags A bitwise combination of the MAGIC_* constants to specify the allowed magic methods (__get, __set, __call) or self::DISALLOW_MAGIC_METHODS for none
  • param int $throw A bitwise combination of the THROW_* constants to specify when exceptions should be thrown
public static createCache(string $namespace, int $defaultLifetime, string $version, ?Psr\Log\LoggerInterface $logger = NULL) : Symfony\Component\Cache\Adapter\AdapterInterface
 

Creates the APCu adapter if applicable.

  • throws \LogicException When the Cache Component isn't available

Methods
private getPropertyPath(Symfony\Component\PropertyAccess\PropertyPath|string $propertyPath) : Symfony\Component\PropertyAccess\PropertyPath
 

Gets a PropertyPath instance and caches it.

private getReadInfo(string $class, string $property) : ?Symfony\Component\PropertyInfo\PropertyReadInfo
 

Guesses how to read the property value.

private getWriteInfo(string $class, string $property, ?mixed $value) : Symfony\Component\PropertyInfo\PropertyWriteInfo
private isPropertyWritable(object $object, string $property) : bool
 

Returns whether a property is writable in the given object.

private readIndex(array $zval, string|int $index) : array
 

Reads a key from an array-like structure.

  • throws \NoSuchIndexException If the array does not implement \ArrayAccess or it is not an array
private readPropertiesUntil(array $zval, Symfony\Component\PropertyAccess\PropertyPathInterface $propertyPath, int $lastIndex, bool $ignoreInvalidIndices = true) : array
 

Reads the path from an object up to a given path index.

  • throws \UnexpectedTypeException if a value within the path is neither object nor array
  • throws \NoSuchIndexException If a non-existing index is accessed
private readProperty(array $zval, string $property, bool $ignoreInvalidProperty = false, bool $isNullSafe = false) : array
 

Reads the value of a property from an object.

  • throws \NoSuchPropertyException If $ignoreInvalidProperty is false and the property does not exist or is not public
private static throwInvalidArgumentException(string $message, array $trace, int $i, string $propertyPath, ?Throwable $previous = NULL) : void
private writeCollection(array $zval, string $property, iterable $collection, Symfony\Component\PropertyInfo\PropertyWriteInfo $addMethod, Symfony\Component\PropertyInfo\PropertyWriteInfo $removeMethod) : void
 

Adjusts a collection-valued property by calling add*() and remove*() methods.

private writeIndex(array $zval, string|int $index, ?mixed $value) : void
 

Sets the value of an index in a given array-accessible value.

  • throws \NoSuchIndexException If the array does not implement \ArrayAccess or it is not an array
private writeProperty(array $zval, string $property, ?mixed $value, bool $recursive = false) : void
 

Sets the value of a property in the given object.

  • throws \NoSuchPropertyException if the property does not exist or is not public
Methods
public static createCache(string $namespace, int $defaultLifetime, string $version, ?Psr\Log\LoggerInterface $logger = NULL) : Symfony\Component\Cache\Adapter\AdapterInterface
 

Creates the APCu adapter if applicable.

  • throws \LogicException When the Cache Component isn't available
private static throwInvalidArgumentException(string $message, array $trace, int $i, string $propertyPath, ?Throwable $previous = NULL) : void
