Interface LookupService

All Superinterfaces:

Layer

public interface LookupService
extends Layer

Service interface for performing lookups from a replicated client group. This service must be used for client groups to ensure that proxies downloaded to client group members are correctly initialized with the important group manager information required to suppress duplicates from the clients at the server-side. That is, the proxy needs access to the TimestampService.
