. This generic method handles all casting in order to spare client classes the work of explicit casts. ThisNodeInfo
class guarantees type safety for these stored info blocks.- Type Parameters:
T
- Specific subtype of ReportingService.Info to retrieve.- Parameters:
clazz
- Class for retrieval.- Returns:
- An object of type T.
