Class NonRegisteringDriver

java.lang.Object

com.mysql.cj.jdbc.NonRegisteringDriver

All Implemented Interfaces:

java.sql.Driver

Direct Known Subclasses:

Driver, 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.bar.Driver").

Constructor Detail

NonRegisteringDriver

public NonRegisteringDriver()
                     throws java.sql.SQLException

Construct a new driver and register it with DriverManager.

Throws:

java.sql.SQLException - if a database error occurs.

Method Detail

getOSName

public static java.lang.String getOSName()

Standardizes OS name information to align with other drivers/clients for MySQL connection attributes.

Returns:

the transformed, standardized OS name

getPlatform

public static java.lang.String getPlatform()

Standardizes platform information to align with other drivers/clients for MySQL connection attributes.

Returns:

the transformed, standardized platform details

acceptsURL

public 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. This driver's protocols start with jdbc:mysql:

Specified by:

acceptsURL in interface java.sql.Driver

Parameters:

url - the URL of the driver.

Returns:

true if this driver accepts the given URL.

Throws:

java.sql.SQLException - if a database access error occurs or the url is null.

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 SQLException if the URL is null or 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. These properties take precedence over any properties sent in the URL.

MySQL protocol takes the form: jdbc:mysql://host:port/database.

Specified by:

connect in interface java.sql.Driver

Parameters:

url - the URL of the database to connect to.

info - a list of arbitrary tag/value pairs as connection arguments.

Returns:

a connection to the URL or null if it isn't us.

Throws:

java.sql.SQLException - if a database access error occurs or the url is null.

getMajorVersion

public int getMajorVersion()

Specified by:

getMajorVersion in interface java.sql.Driver

getMinorVersion

public int getMinorVersion()

Specified by:

getMinorVersion in interface java.sql.Driver

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

Specified by:

getPropertyInfo in interface java.sql.Driver

Throws:

Specified by:

getParentLogger in interface java.sql.Driver

Throws:

java.sql.SQLFeatureNotSupportedException
