public CacheContextsManager::assertValidTokens($context_tokens)
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.
