protected AbstractServiceConfigurationFactory.Entry<ModbusMaster> createService(UserInformation userInformation,
                                                                                String configurationId,

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<ModbusMaster>

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,
                              ModbusMaster 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<ModbusMaster>

updateService

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

Description copied from class: AbstractServiceConfigurationFactory

Update a service configuration

If a new service entry is returned the old one will get disposed after the call returns

Specified by:

updateService in class AbstractServiceConfigurationFactory<ModbusMaster>

configurationId - the configuration to update

entry - the original service entry

parameters - the new parameters

Returns:

the new service entry or null if the entry did not change

Throws:

Exception - if anything goes wrong
