retryWithSameServer

public rx.Observable<T> retryWithSameServer(Server server,
                                   rx.Observable<T> forServer)

Gets the Observable that represents the result of executing on a server, after possible retries as dictated by RetryHandler. During retry, any errors that are retriable are consumed by the function and will not be observed by the external Observer. If number of retries exceeds the maximal retries allowed on one server, a final error will be emitted by the returned Observable.

Parameters:

forServer - A lazy Observable that does not start execution until it is subscribed to

retryWithSameServer

public T retryWithSameServer(Server server,
                    LoadBalancerExecutable<T> executable)
                      throws java.lang.Exception

Take a server and LoadBalancerExecutable to execute the task on the server with possible retries in blocking mode.

Throws:

java.lang.Exception
