GenericMetadata

class GenericMetadata implements MetadataInterface

A generic container of {@link Constraint} objects.

This class supports serialization and cloning.

Properties

Constraint[] $constraints
array $constraintsByGroup
int $cascadingStrategy The strategy for cascading objects.
int $traversalStrategy The strategy for traversing traversable objects.

Methods

string[]
__sleep()

Returns the names of the properties that should be serialized.

__clone()

Clones this object.

$this
addConstraint(Constraint $constraint)

Adds a constraint.

$this
addConstraints(array $constraints)

Adds an list of constraints.

Constraint[]
getConstraints()

Returns all constraints of this element.

bool
hasConstraints()

Returns whether this element has any constraints.

Constraint[]
findConstraints(string $group)

Returns all constraints for a given validation group.

int
getCascadingStrategy()

Returns the strategy for cascading objects.

int
getTraversalStrategy()

Returns the strategy for traversing traversable objects.

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()

Returns the strategy for cascading objects.

Return Value

int The cascading strategy

int getTraversalStrategy()

Returns the strategy for traversing traversable objects.

Return Value

int The traversal strategy
