public class: NonRegisteringDriver [javadoc | source]
java.lang.Object
   com.mysql.jdbc.NonRegisteringDriver

All Implemented Interfaces:
    Driver

Direct Known Subclasses:
    ReplicationDriver, Driver, NonRegisteringReplicationDriver, Driver

The Java SQL framework allows for multiple database drivers. Each driver should supply a class that implements the Driver interface

The DriverManager will try to load as many drivers as it can find and then for any given connection request, it will ask each driver in turn to try to connect to the target URL.

It is strongly recommended that each Driver class should be small and standalone so that the Driver class can be loaded and queried without bringing in vast quantities of supporting code.

When a Driver class is loaded, it should create an instance of itself and register it with the DriverManager. This means that a user can load and register a driver by doing Class.forName("foo.bah.Driver")

Field Summary
public static final  String DBNAME_PROPERTY_KEY    Key used to retreive the database value from the properties instance passed to the driver. 
public static final  boolean DEBUG    Should the driver generate debugging output? 
public static final  int HOST_NAME_INDEX    Index for hostname coming out of parseHostPortPair(). 
public static final  String HOST_PROPERTY_KEY    Key used to retreive the hostname value from the properties instance passed to the driver. 
public static final  String NUM_HOSTS_PROPERTY_KEY     
public static final  String PASSWORD_PROPERTY_KEY    Key used to retreive the password value from the properties instance passed to the driver. 
public static final  int PORT_NUMBER_INDEX    Index for port # coming out of parseHostPortPair(). 
public static final  String PORT_PROPERTY_KEY    Key used to retreive the port number value from the properties instance passed to the driver. 
public static final  String PROPERTIES_TRANSFORM_KEY     
public static final  boolean TRACE    Should the driver generate method-call traces? 
public static final  String USE_CONFIG_PROPERTY_KEY     
public static final  String USER_PROPERTY_KEY    Key used to retreive the username value from the properties instance passed to the driver.

Method from com.mysql.jdbc.NonRegisteringDriver Detail:
 public boolean acceptsURL(String url) throws SQLException 
    Typically, drivers will return true if they understand the subprotocol specified in the URL and false if they don't. This driver's protocols start with jdbc:mysql:
 public Connection connect(String url,
    Properties info) throws SQLException 
    Try to make a database connection to the given URL. The driver should return "null" if it realizes it is the wrong kind of driver to connect to the given URL. This will be common, as when the JDBC driverManager is asked to connect to a given URL, it passes the URL to each loaded driver in turn.

    The driver should raise an SQLException if it is the right driver to connect to the given URL, but has trouble connecting to the database.

    The java.util.Properties argument can be used to pass arbitrary string tag/value pairs as connection arguments.

    My protocol takes the form:

    
    jdbc:mysql://host:port/database
    
    

 protected Connection connectReplicationConnection(String url,
    Properties info) throws SQLException 
 public String database(Properties props) 
    Returns the database property from props
 public int getMajorVersion() 
    Gets the drivers major version number
 static int getMajorVersionInternal() 
    Gets the drivers major version number
 public int getMinorVersion() 
    Get the drivers minor version number
 static int getMinorVersionInternal() 
    Get the drivers minor version number
 public DriverPropertyInfo[] getPropertyInfo(String url,
    Properties info) throws SQLException 
    The getPropertyInfo method is intended to allow a generic GUI tool to discover what properties it should prompt a human for in order to get enough information to connect to a database.

    Note that depending on the values the human has supplied so far, additional values may become necessary, so it may be necessary to iterate through several calls to getPropertyInfo

 public String host(Properties props) 
    Returns the hostname property
 public boolean jdbcCompliant() 
    Report whether the driver is a genuine JDBC compliant driver. A driver may only report "true" here if it passes the JDBC compliance tests, otherwise it is required to return false. JDBC compliance requires full support for the JDBC API and full support for SQL 92 Entry Level.

    MySQL is not SQL92 compliant

 protected static String[] parseHostPortPair(String hostPortPair) throws SQLException 
    Parses hostPortPair in the form of [host][:port] into an array, with the element of index HOST_NAME_INDEX being the host (or null if not specified), and the element of index PORT_NUMBER_INDEX being the port (or null if not specified).
 public Properties parseURL(String url,
    Properties defaults) throws SQLException 
 public int port(Properties props) 
    Returns the port number property
 public String property(String name,
    Properties props) 
    Returns the given property from props
