register(IContext? context) → Future<void>

Registers the given connection in all referenced discovery services. This method can be used for dynamic service discovery.

resolve(IContext? context) → Future<ConfigParams>

resolveAll(IContext? context) → Future<ConfigParams>

Resolves all component connection. If connections are configured to be retrieved from Discovery service it finds a IDiscovery and resolves the connection there.
