Class

ConstraintValidatorFactory

Defines a constraint validator factory that works with container injection.

Namespace

Drupal\Core\Validation

Code

public function getInstance(Constraint $constraint) {
  $class_name = $constraint
    ->validatedBy();

  // Constraint validator instances should always be initialized newly and
  // never shared, because the current validation context is getting injected
  // into them through setter injection and in a case of a recursive
  // validation where a validator triggers a validation chain leading to the
  // same validator the context of the first call would be exchanged with the
  // one of the subsequent validation chain.
  return $this->classResolver
    ->getInstanceFromDefinition($class_name);
