public function CacheContextsManager::assertValidTokens in Zircon Profile 8
Same name and namespace in other branches
- 8.0 core/lib/Drupal/Core/Cache/Context/CacheContextsManager.php \Drupal\Core\Cache\Context\CacheContextsManager::assertValidTokens()
Asserts the context tokens are valid
Similar to ::validateTokens, this method returns boolean TRUE when the context tokens are valid, and FALSE when they are not instead of returning NULL when they are valid and throwing a \LogicException when they are not. This function should be used with the assert() statement.
Parameters
mixed $context_tokens: Variable to be examined - should be array of context_tokens.
Return value
bool TRUE if context_tokens is an array of valid tokens.
