Package com.exonum.binding.core.service

Interface Configuration

public interface Configuration
Configuration parameters of Exonum service.

Network administrators agree on and pass the configuration parameters as a service-specific protobuf message when adding that service instance to the network. After Exonum starts the service, it passes the configuration parameters to the newly created service instance.

Reconfiguration of a started service may be implemented with a supervisor service and Configurable interface.
