is replaced. Refreshes the state if any of the dependencies was changed.Updates of
dependencies
are not atomic: If this method is called concurrently multiple times, the resulting dependencies may not correspond to a serializable execution.If an dependency triggers a concurrent state refresh, then the state refresh may see an inconsistent set of dependencies and therefore derive an inconsistent state. This however is only temporary as in this case another state refresh will be triggered at the end.
