Method Detail

afterHandshake

public java.net.Socket afterHandshake()
                               throws java.net.SocketException,
                                      java.io.IOException

Description copied from interface: SocketFactory

Called by the driver after issuing the MySQL protocol handshake and reading the results of the handshake.

Specified by:

afterHandshake in interface SocketFactory

Returns:

the socket to use after the handshake

Throws:

java.net.SocketException - if a socket error occurs

java.io.IOException - if an I/O error occurs

See Also:

SocketFactory.afterHandshake()

beforeHandshake

public java.net.Socket beforeHandshake()
                                throws java.net.SocketException,
                                       java.io.IOException

Description copied from interface: SocketFactory

Called by the driver before issuing the MySQL protocol handshake. Should return the socket instance that should be used during the handshake.

Specified by:

beforeHandshake in interface SocketFactory

Returns:

the socket to use before the handshake

Throws:

java.net.SocketException - if a socket error occurs

java.io.IOException - if an I/O error occurs

See Also:

SocketFactory.beforeHandshake()

connect

public java.net.Socket connect(java.lang.String host,
                      int portNumber,
                      java.util.Properties props)
                        throws java.net.SocketException,
                               java.io.IOException

Description copied from interface: SocketFactory

Creates a new socket using the given properties. Properties are parsed by the driver from the URL. All properties other than sensitive ones (user and password) are passed to this method. The driver will instantiate the socket factory with the class name given in the property "socketFactory", where the standard is com.mysql.jdbc.StandardSocketFactory Implementing classes are responsible for handling synchronization of this method (if needed).

Specified by:

connect in interface SocketFactory

Parameters:

host - the hostname passed in the JDBC URL. It will be a single hostname, as the driver parses multi-hosts (for failover) and calls this method for each host connection attempt.

portNumber - the port number to connect to (if required).

props - properties passed to the driver via the URL and/or properties instance.

Returns:

a socket connected to the given host

Throws:

java.net.SocketException - if a socket error occurs

java.io.IOException - if an I/O error occurs

isLocallyConnected

public boolean isLocallyConnected(ConnectionImpl conn)
                           throws java.sql.SQLException

Specified by:

isLocallyConnected in interface SocketMetadata

Throws:

java.sql.SQLException
