Verifies that this expression is configured correctly.

Example: All configured data selectors must be valid.

Note that for checking integrity the execution metadata state must be passed prepared as achieved by ::prepareExecutionMetadataState() and the expression must apply all metadata state preparations during its integrity check as it does in ::prepareExecutionMetadataState(). This allows for efficient integrity checks of expression trees; e.g. see \Drupal\rules\Engine\ActionExpressionContainer::checkIntegrity().

Parameters

\Drupal\rules\Context\ExecutionMetadataStateInterface $metadata_state: The execution metadata state, prepared until right before this expression.

bool $apply_assertions: (optional) Whether to apply metadata assertions while preparing the execution metadata state. Defaults to TRUE.

Return value

\Drupal\rules\Engine\IntegrityViolationList A list object containing \Drupal\rules\Engine\IntegrityViolation objects.
