Examples of de.novanic.eventservice.config.EventServiceConfiguration

de.novanic.eventservice.config.EventServiceConfiguration
An EventServiceConfiguration holds the configuration for {@link de.novanic.eventservice.client.event.service.EventService}. The time for a timeout and the min- and max-waiting-time can be configured.

- Min waiting time - Listening should hold at least for min waiting time.
- Max waiting time - Listening shouldn't hold longer than max waiting time.
- Timeout time - Max time for a listen cycle. If the timeout time is exceeded, the client will be deregistered. @author sstrohschein
