2. 10 core/modules/user/src/ContextProvider/CurrentUserContext.php \Drupal\user\ContextProvider\CurrentUserContext::getRuntimeContexts()
3. 11.x core/modules/user/src/ContextProvider/CurrentUserContext.php \Drupal\user\ContextProvider\CurrentUserContext::getRuntimeContexts()

Gets runtime context values for the given context IDs.

For context-aware plugins to function correctly, all of the contexts that they require must be populated with values. So this method should set a value for each context that it adds. For example:

  // Determine a specific node to pass as context to a block.
  $node = ...

  // Set that specific node as the value of the 'node' context.
  $context = EntityContext::fromEntity($node);
  return ['node' => $context];

On the other hand, there are cases, on which providers no longer are possible to provide context objects, even without the value, so the caller should not expect it.

Parameters

string[] $unqualified_context_ids: The requested context IDs. The context provider must only return contexts for those IDs.

Return value

\Drupal\Core\Plugin\Context\ContextInterface[] The determined available contexts, keyed by the unqualified context_id.

Overrides ContextProviderInterface::getRuntimeContexts
