  1. 4.0.x src/TypedDataResolver.php \Drupal\ctools\TypedDataResolver::getContextFromProperty()

Convert a property to a context.

This method will respect the value of contexts as well, so if a context object is pass that contains a value, the appropriate value will be extracted and injected into the resulting context object if available.

Parameters

string $property_path: The name of the property.

\Drupal\Core\Plugin\Context\ContextInterface $context: The context from which we will extract values if available.

Return value

\Drupal\Core\Plugin\Context\Context A context object that represents the definition & value of the property.

Throws

\Exception
