Details

string[] __sleep()

Returns the names of the properties that should be serialized.

Return Value

string[]

__clone()

Clones this object.

$this addConstraint(Constraint $constraint)

Adds a constraint.

If the constraint {@link Valid} is added, the cascading strategy will be changed to {@link CascadingStrategy::CASCADE}. Depending on the $traverse property of that constraint, the traversal strategy will be set to one of the following:

  • {@link TraversalStrategy::IMPLICIT} if $traverse is enabled
  • {@link TraversalStrategy::NONE} if $traverse is disabled

Parameters

Constraint $constraint

Return Value

$this

Exceptions

ConstraintDefinitionException When trying to add the {@link Traverse} constraint

$this addConstraints(array $constraints)

Adds an list of constraints.

Parameters

array $constraints The constraints to add

Return Value

$this

Constraint[] getConstraints()

Returns all constraints of this element.

Return Value

Constraint[] A list of Constraint instances

bool hasConstraints()

Returns whether this element has any constraints.

Return Value

bool

Constraint[] findConstraints(string $group)

Returns all constraints for a given validation group.

Parameters

string $group The validation group

Return Value

Constraint[] A list of constraint instances

int getCascadingStrategy()

Class nodes are never cascaded.

{@inheritdoc}

Return Value

int The cascading strategy

int getTraversalStrategy()

Returns the strategy for traversing traversable objects.

Return Value

int The traversal strategy

__construct(string $class)

Parameters

string $class

string getClassName()

Returns the name of the backing PHP class.

Return Value

string The name of the backing class

string getDefaultGroup()

Returns the name of the default group for this class.

For each class, the group "Default" is an alias for the group "", where is the non-namespaced name of the class. All constraints implicitly or explicitly assigned to group "Default" belong to both of these groups, unless the class defines a group sequence.

If a class defines a group sequence, validating the class in "Default" will validate the group sequence. The constraints assigned to "Default" can still be validated by validating the class in "".

Return Value

string The name of the default group

$this addPropertyConstraint(string $property, Constraint $constraint)

Adds a constraint to the given property.

Parameters

string $property The name of the property
Constraint $constraint The constraint

Return Value

$this

$this addPropertyConstraints(string $property, array $constraints)

Parameters

string $property
array $constraints

Return Value

$this

$this addGetterConstraint(string $property, Constraint $constraint)

Adds a constraint to the getter of the given property.

The name of the getter is assumed to be the name of the property with an uppercased first letter and either the prefix "get" or "is".

Parameters

string $property The name of the property
Constraint $constraint The constraint

Return Value

$this

$this addGetterMethodConstraint(string $property, string $method, Constraint $constraint)

Adds a constraint to the getter of the given property.

Parameters

string $property The name of the property
string $method The name of the getter method
Constraint $constraint The constraint

Return Value

$this

$this addGetterConstraints(string $property, array $constraints)

Parameters

string $property
array $constraints

Return Value

$this

$this addGetterMethodConstraints(string $property, string $method, array $constraints)

Parameters

string $property
string $method
array $constraints

Return Value

$this

mergeConstraints(ClassMetadata $source)

Merges the constraints of the given metadata into this object.

Parameters

ClassMetadata $source

bool hasPropertyMetadata(string $property)

Check if there's any metadata attached to the given named property.

Parameters

string $property The property name

Return Value

bool

PropertyMetadataInterface[] getPropertyMetadata(string $property)

Returns all metadata instances for the given named property.

If your implementation does not support properties, simply throw an exception in this method (for example a BadMethodCallException).

Parameters

string $property The property name

Return Value

PropertyMetadataInterface[] A list of metadata instances. Empty if no metadata exists for the property.

string[] getConstrainedProperties()

Returns the names of all constrained properties.

Return Value

string[] A list of property names

$this setGroupSequence(array $groupSequence)

Sets the default group sequence for this class.

Parameters

array $groupSequence An array of group names

Return Value

$this

Exceptions

GroupDefinitionException

bool hasGroupSequence()

Returns whether the "Default" group is overridden by a group sequence.

If it is, you can access the group sequence with {@link getGroupSequence()}.

Return Value

bool Returns true if the "Default" group is overridden

GroupSequence|null getGroupSequence()

Returns the group sequence that overrides the "Default" group for this class.

Return Value

GroupSequence|null The group sequence or null

ReflectionClass getReflectionClass()

Returns a ReflectionClass instance for this class.

Return Value

ReflectionClass

setGroupSequenceProvider(bool $active)

Sets whether a group sequence provider should be used.

Parameters

bool $active

Exceptions

GroupDefinitionException

bool isGroupSequenceProvider()

Returns whether the "Default" group is overridden by a dynamic group sequence obtained by the validated objects.

If this method returns true, the class must implement {@link \Symfony\Component\Validator\GroupSequenceProviderInterface}. This interface will be used to obtain the group sequence when an object of this class is validated.

Return Value

bool Returns true if the "Default" group is overridden by a dynamic group sequence
