They provide a list of dependencies for a service or the classes of a Java package. When the dependencies are fulfilled and all required interfaces have been registered in the service registry, the starter is started. On the other hand, when a dependency is dropped from the service registry, the starter is stopped. https://sillysky.net/docs/nyssr/services/iservice/ Tue, 14 Oct 2025 00:00:00 +0000 https://sillysky.net/docs/nyssr/services/iservice/ The IService helper interface is not mandatory for defining services. It only simplifies the initialization and removal of services. Services activation In this method the service can be initialized and registered to the service registry. Possible exceptions are caught and logged by the system. void activate(@NotNull IServiceRegistry aServiceRegistry) throws Exception; Deactivating the service In this method the service can be de-initialized and deregistered from the service registry. void deactivate(@NotNull IServiceRegistry aServiceRegistry) throws Exception; https://sillysky.net/docs/nyssr/services/iservicedependencylist/ Tue, 14 Oct 2025 00:00:00 +0000 https://sillysky.net/docs/nyssr/services/iservicedependencylist/ This is a helper class used by the service registry to collect dependencies from service starters. Add a dependency To add a dependency on a singleton object, use the corresponding class. void add(@NotNull Class aService); For dependencies that are not a singleton, you must include a filter to distinguish the individual instances of the class. Filters are a list of properties separated by commas, such as "key1=val1,key2=val2". void add(@NotNull Class aService, @NotNull String aProperties); An example is the specification of a namespace. https://sillysky.net/docs/nyssr/services/iservicelistener/ Tue, 14 Oct 2025 00:00:00 +0000 https://sillysky.net/docs/nyssr/services/iservicelistener/ A service listener is registered at the service registry to receive service registration and de-registration information. A service listener implements two methods. This method is called when a service is registered with the service registry. void notifyServiceStarted(@NotNull IServiceRegistry aServiceRegistry, @NotNull Class aClass, @NotNull Object aInstance, @Nullable CStringProperties aProperties) throws Exception; The other method is called when a service is deregistered. void notifyServiceStopped(@NotNull IServiceRegistry aServiceRegistry, @NotNull Class aClass, @NotNull Object aInstance, @Nullable CStringProperties aProperties) throws Exception; https://sillysky.net/docs/nyssr/services/iservicestarter/ Tue, 14 Oct 2025 00:00:00 +0000 https://sillysky.net/docs/nyssr/services/iservicestarter/ The IServiceStarter interface is used to define a starting point for the classes in a Java package. In addition, the class that implements this interface is usually the only class in a package that is not package private. This means that all other classes are hidden in the package. The interface is registered to the service registry as a starter. It defines a list of dependencies that the classes in the package have. https://sillysky.net/docs/nyssr/services/list-of-wellknown-services/ Tue, 14 Oct 2025 00:00:00 +0000 https://sillysky.net/docs/nyssr/services/list-of-wellknown-services/ This list briefly describes various services that are registered at the service registry. Class Module/Plugin Properties Description IHelperForLocalMicroServices NY_MicroServicePlugIn The service simplifies the registration and de-registration of microservices. IKernelConfiguration Kernel A service to access the configuration. IMessageLoggerFactory Kernel A factory for creating message loggers. IMessageSender Kernel The service that sends messages. IMicroServiceRegistryCollector NY_MicroServicePlugIn This service collects broadcasts from microservice registries and facilitates sending messages to microservices. INameDb Kernel A database where names for record IDs, targets, etc.
