2. 11.x core/lib/Drupal/Core/Theme/Component/ComponentValidator.php \Drupal\Core\Theme\Component\ComponentValidator::validateDefinition()

Validates the component metadata file.

A valid component metadata file can be validated against the metadata-author.schema.json, plus the ability of classes and interfaces in the `type` property.

Parameters

array $definition: The definition to validate.

bool $enforce_schemas: TRUE if schema definitions are mandatory.

Return value

bool TRUE if the component is valid.

Throws

\Drupal\sdc\Exception\InvalidComponentException

File

core/modules/sdc/src/Component/ComponentValidator.php, line 57

Class

ComponentValidator

Validates a component based on its definition and the component schema.

Namespace

Drupal\sdc\Component
