Method Detail

### afterHandshake

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

  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

### beforeHandshake

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

  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

### connect

    public java.net.Socket connect(java.lang.String hostname,
                                   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:
    `hostname` - 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
  See Also:
    `com.mysql.jdbc.SocketFactory#createSocket(Properties)`
