Interface SelfConfiguringComponent

public interface SelfConfiguringComponent

A SelfConfiguringComponent is a configurable component which maintains its state. A SelfConfiguringComponent exposes its configuration information to the ConfigurationService and therefore can be have its configuration updated locally or remotely through the ConfigurationService APIs. However, a SelfConfiguringComponent does not rely on the ConfigurationService to keep the storage of its configuration. The configuration state is kept internally in the SelfConfiguringComponent or derived at runtime from other resources such system resources.
An example of a SelfConfiguringComponent is the NetworkService whose state is kept in the operating system instead of in the ConfigurationService.
