private function RecursiveContextualValidator::validateGenericNode in Plug 7

Validates a node that is not a class node.

Currently, two such node types exist:

property nodes, which consist of the value of an object's property together with a {@link PropertyMetadataInterface} instance
generic nodes, which consist of a value and some arbitrary constraints defined in a {@link MetadataInterface} container

In both cases, the value is validated against all constraints defined in the passed metadata object. Then, if the value is an instance of {@link \Traversable} and the selected traversal strategy permits it, the value is traversed and each nested object validated against its own constraints. Arrays are always traversed.

Parameters

mixed $value The validated value:

object|null $object The current object:

string $cacheKey The key for caching: the validated value

MetadataInterface $metadata The metadata of the: value

string $propertyPath The property path leading: to the value

string[] $groups The groups in which the: value should be validated

string[]|null $cascadedGroups The groups in which: cascaded objects should be validated

int $traversalStrategy The strategy used for: traversing the value

ExecutionContextInterface $context The current execution context:

  // If no specific traversal strategy was requested when this method
  // was called, use the traversal strategy of the node's metadata

    // Keep the STOP_RECURSION flag, if it was set
    $traversalStrategy = $metadata
      ->getTraversalStrategy() | $traversalStrategy & TraversalStrategy::STOP_RECURSION;
  }

  // The $cascadedGroups property is set, if the "Default" group is
  // overridden by a group sequence
  // See validateClassNode()
  $cascadedGroups = count($cascadedGroups) > 0 ? $cascadedGroups : $groups;
  if (is_array($value)) {

    // Arrays are always traversed, independent of the specified
    // traversal strategy
    // (BC with Symfony < 2.5)
    $this
      ->validateEachObjectIn($value, $propertyPath, $cascadedGroups, $traversalStrategy & TraversalStrategy::STOP_RECURSION, $context);
    return;
  }

  // If the value is a scalar, pass it anyway, because we want
  // a NoSuchMetadataException to be thrown in that case
  // (BC with Symfony < 2.5)
  $this
    ->validateObject($value, $propertyPath, $cascadedGroups, $traversalStrategy, $context);

  // Currently, the traversal strategy can only be TRAVERSE for a
  // generic node if the cascading strategy is CASCADE. Thus, traversable
  // objects will always be handled within validateObject() and there's
  // nothing more to do here.
