AbstractFrontendService

abstract class AbstractFrontendService extends CompositeService with FrontendService

A AbstractFrontendService is an abstraction for fronted service. An frontend service will receive client requests and translate them to serverable operations or backend operations. It also support exposing itself by ServiceDiscovery if the concrete frontend service has a Discovery Service as its child.
