com.mysql.jdbc
Class NonRegisteringDriver  

java.lang.Object
  com.mysql.jdbc.NonRegisteringDriver

All Implemented Interfaces:

java.sql.Driver

Direct Known Subclasses:

Driver

---

public class NonRegisteringDriver

extends java.lang.Object

implements java.sql.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")

NonRegisteringDriver()           Construct a new driver and register it with DriverManager

 

Method Summary
boolean	acceptsURL(java.lang.String url)           Typically, drivers will return true if they understand the subprotocol specified in the URL and false if they don't.

(package private) static int	getMinorVersionInternal()           Get the drivers minor version number
java.sql.DriverPropertyInfo[]	getPropertyInfo(java.lang.String url, java.util.Properties info)           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.
java.lang.String	host(java.util.Properties props)           Returns the hostname property
boolean	jdbcCompliant()           Report whether the driver is a genuine JDBC compliant driver.
protected static java.lang.String[]	parseHostPortPair(java.lang.String hostPortPair)           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).
java.util.Properties	parseURL(java.lang.String url, java.util.Properties defaults)           Constructs a new DriverURL, splitting the specified URL into its component parts
int	port(java.util.Properties props)           Returns the port number property
java.lang.String	property(java.lang.String name, java.util.Properties props)           Returns the given property from props

Constructor Detail

NonRegisteringDriver

public NonRegisteringDriver()
                     throws java.sql.SQLException

Construct a new driver and register it with DriverManager

Method Detail

getMajorVersion

public int getMajorVersion()

Gets the drivers major version number

Specified by:

getMajorVersion in interface java.sql.Driver

---

getMinorVersion

public int getMinorVersion()

Get the drivers minor version number

Specified by:

getMinorVersion in interface java.sql.Driver

---

getPropertyInfo

public java.sql.DriverPropertyInfo[] getPropertyInfo(java.lang.String url,
                                                     java.util.Properties info)
                                              throws java.sql.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

Specified by:

getPropertyInfo in interface java.sql.Driver

acceptsURL

public boolean acceptsURL(java.lang.String url)
                   throws java.sql.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:

Specified by:

acceptsURL in interface java.sql.Driver

---

connect

public java.sql.Connection connect(java.lang.String url,
                                   java.util.Properties info)
                            throws java.sql.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 java.sql.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
 

Specified by:

connect in interface java.sql.Driver

---

database

public java.lang.String database(java.util.Properties props)

Returns the database property from props

---

host

public java.lang.String host(java.util.Properties props)

Returns the hostname property

---

jdbcCompliant

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

Specified by:

jdbcCompliant in interface java.sql.Driver

---

parseURL

public java.util.Properties parseURL(java.lang.String url,
                                     java.util.Properties defaults)
                              throws java.sql.SQLException

Constructs a new DriverURL, splitting the specified URL into its component parts

---

port

public int port(java.util.Properties props)

Returns the port number property

---

property

                                 java.util.Properties props)

---

parseHostPortPair

protected static java.lang.String[] parseHostPortPair(java.lang.String hostPortPair)
                                               throws java.sql.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).

---
