public GenericMetadata addConstraints(array $constraints)

Adds an list of constraints.

Parameters

array $constraints The constraints to add

Return Value

GenericMetadata This object

public Constraint[] getConstraints()

Returns all constraints of this element.

Return Value

Constraint[] A list of Constraint instances

in GenericMetadata at line 196
public bool hasConstraints()

Returns whether this element has any constraints.

Return Value

bool

Parameters

string $group The validation group

Return Value

Constraint[] A list of constraint instances

in GenericMetadata at line 216
public int getCascadingStrategy()

Returns the strategy for cascading objects.

Return Value

int The cascading strategy

public accept(ValidationVisitorInterface $visitor, mixed $value, string|string[] $group, string $propertyPath)

Exists for compatibility with the deprecated {@link Symfony\Component\Validator\MetadataInterface}.

Should not be used.

Implemented for backward compatibility with Symfony < 2.5.

Parameters

ValidationVisitorInterface $visitor The visitor implementing the validation logic
mixed $value The value to validate
string|string[] $group The validation group to validate in
string $propertyPath The current property path in the validation graph
