Method Detail

searchProbableMaster

public static void searchProbableMaster(AuroraListener listener,
                                        HostAddress probableMaster,
                                        SearchFilter searchFilter)
                                 throws QueryException

Connect aurora probable master. Aurora master change in time. The only way to check that a server is a master is to asked him.

Parameters:

listener - aurora failover to call back if master is found

probableMaster - probable master host

searchFilter - search filter

Throws:

QueryException - exception

loop

public static void loop(AuroraListener listener,
                        List<HostAddress> addresses,
                        SearchFilter searchFilter)
                 throws QueryException

loop until found the failed connection.

Parameters:

listener - current failover

addresses - list of HostAddress to loop

searchFilter - search parameter

Throws:

QueryException - if not found

getNewProtocol
