RuleProviderRegistryCache (Windup Engine - Config API 5.3.0.Alpha1 API)

```
public interface RuleProviderRegistryCache
```
This class provides convenience methods for retrieving a RuleProviderRegistry. The registry is cached for a period of time in order to improve performance. This is useful for cases in which you need to repeatedly query the registry for information, such as when looking up metadata in the user interface.
