Constructor Detail

AuroraProtocol

public AuroraProtocol(UrlParser url,
                      ReentrantLock lock)

Method Detail

searchProbableMaster

public static void searchProbableMaster(AuroraListener listener,
                                        HostAddress probableMaster)

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

loop

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

loop until found the failed connection.

Parameters:

listener - current failover

addresses - list of HostAddress to loop

searchFilter - search parameter

Throws:

SQLException - if not found

getNewProtocol

public static AuroraProtocol getNewProtocol(FailoverProxy proxy,
                                            UrlParser urlParser)

Initialize new protocol instance.

Parameters:

proxy - proxy

urlParser - connection string data's

Returns:

new AuroraProtocol

isMasterConnection

SQLException

checkIfMaster

public boolean checkIfMaster()
                      throws SQLException

Aurora best way to check if a node is a master : is not in read-only mode.

Specified by:

checkIfMaster in interface Protocol

Overrides:

checkIfMaster in class AbstractConnectProtocol

Returns:

indicate if master has been found

Throws:

SQLException - if requesting infos for server fail.
