Description copied from class: AbstractServiceConfigurationFactory

Create a new service instance

The method must also register the service with the OSGi bundle context if needed. The service registration must then be placed into the result that is returned. This is an optional step. There is no need to register the created service.

Specified by:

createService in class AbstractServiceConfigurationFactory<ModbusSlave>

configurationId - the configuration id for which the service should be created

context - the bundle context

parameters - the initial parameters

Returns:

a new entry instance which holds the service. This method must never return null

Throws:

Exception - if anything goes wrong

disposeService

protected void disposeService(UserInformation userInformation,
                  String configurationId,
                  ModbusSlave service)

Description copied from class: AbstractServiceConfigurationFactory

Dispose a service

If the service entry contains a service handle, the service is automatically unregistered.

Specified by:

disposeService in class AbstractServiceConfigurationFactory<ModbusSlave>

updateService

protected AbstractServiceConfigurationFactory.Entry<ModbusSlave> updateService(UserInformation userInformation,
                                                                   String configurationId,
                                                                   AbstractServiceConfigurationFactory.Entry<ModbusSlave> entry,
                                                                   Map<String,String> parameters)
                                                                        throws Exception

Description copied from class: AbstractServiceConfigurationFactory

Specified by:
