Method Detail

registerServices

void registerServices(Map<Service,String> mapServices)

Adds a set of Services to be monitored providing life support. If any of the services are not running they are started either via the configured ConfigurableCacheFactory iff provided or the provided Service.

Parameters:

mapServices - a map of Services where values are non-scoped service names

unregisterServices

void unregisterServices(Set<Service> setServices)

Removes the supplied set of Services from monitoring. Note that the services are not being stopped; they are just removed from the list of Services that are being monitored.

Parameters:

setServices - the set of Services to be removed from monitoring

stopMonitoring

void stopMonitoring()

Stop monitoring all registered services. Note that the services are not being stopped; they are just removed from the list of Services that are being monitored.

isMonitoring

boolean isMonitoring()

Returns true iff the ServiceMonitor is monitoring a number of services.

Returns:

returns true iff the ServiceMonitor is monitoring a number of services

setConfigurableCacheFactory

void setConfigurableCacheFactory(ConfigurableCacheFactory ccf)

Set the ConfigurableCacheFactory a ServiceMonitor can operate with. Setting the ConfigurableCacheFactory should be performed prior to registering services or requires a stopMonitoring() and registerServices(Map) call.

Parameters:

ccf - the ConfigurableCacheFactory used to start the service

getThread

Thread getThread()

Return the thread used by this ServiceMonitor.
