Class TickingClockService

java.lang.Object

org.apache.isis.extensions.commandreplay.secondary.clock.TickingClockService

@Service
 @Named(value="isisExtensionsCommandReplaySecondary.TickingClockService")
 @Order(value=0)
public class TickingClockService
extends Object

Only enabled for the secondary profile, where it sets up the framework to use TickingFixtureClock so that time can be changed dynamically when running.

As an additional safeguard, if the configuration keys to access the primary are not provided, then the service will not initialize.

IMPORTANT: the methods provided by this service are not thread-safe, because the clock is a globally-scoped singleton rather than a thread-local. These methods should therefore only be used in single-user systems, eg a replay secondary.
