public function ConfigFactory::getCacheKeys

public ConfigFactory::getCacheKeys()

The cache keys associated with the state of the config factory.

All state information that can influence the result of a get() should be included. Typically, this includes a key for each override added via addOverride(). This allows external code to maintain caches of configuration data in addition to or instead of caches maintained by the factory.

Return value
