Interface CloudCallService

public interface CloudCallService

The CloudCallService provides helper methods to make a request/response conversation with the remote server. The call methods deal with the logic required to build request messages and track the corresponding responses. All call methods are synchronous; after a request is issued, the implementation will wait for the response to arrive or a timeout occurs. The timeout interval used by the service is configurable as a property of the DataTransportService.
