ExpiringClassFactory

Overview

The ExpiringClassFactory abstract class provides privides methods needed by Class Factories that should periodically expire acquired service instances.

For example, PerClientClassFactory class disposes all service instances acquired by a client if there were no requests from this client for some time.

This class doesn't provide any service instance acquiring functionality, as it's main purpose is to provide common expiration timer handling routines.
