PHP ExecutionContextInterface::isObjectInitialized方法代码示例

 /**
  * Validates a class node.
  *
  * A class node is a combination of an object with a {@link ClassMetadataInterface}
  * instance. Each class node (conceptionally) has zero or more succeeding
  * property nodes:
  *
  *     (Article:class node)
  *                \
  *        ($title:property node)
  *
  * This method validates the passed objects against all constraints defined
  * at class level. It furthermore triggers the validation of each of the
  * class' properties against the constraints for that property.
  *
  * If the selected traversal strategy allows traversal, the object is
  * iterated and each nested object is validated against its own constraints.
  * The object is not traversed if traversal is disabled in the class
  * metadata.
  *
  * If the passed groups contain the group "Default", the validator will
  * check whether the "Default" group has been replaced by a group sequence
  * in the class metadata. If this is the case, the group sequence is
  * validated instead.
  *
  * @param object                    $object            The validated object
  * @param string                    $cacheKey          The key for caching
  *                                                     the validated object
  * @param ClassMetadataInterface    $metadata          The class metadata of
  *                                                     the object
  * @param string                    $propertyPath      The property path leading
  *                                                     to the object
  * @param string[]                  $groups            The groups in which the
  *                                                     object should be validated
  * @param string[]|null             $cascadedGroups    The groups in which
  *                                                     cascaded objects should
  *                                                     be validated
  * @param int                       $traversalStrategy The strategy used for
  *                                                     traversing the object
  * @param ExecutionContextInterface $context           The current execution context
  *
  * @throws UnsupportedMetadataException  If a property metadata does not
  *                                       implement {@link PropertyMetadataInterface}
  * @throws ConstraintDefinitionException If traversal was enabled but the
  *                                       object does not implement
  *                                       {@link \Traversable}
