## com.mysql.jdbc
Class NonRegisteringDriver

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

All Implemented Interfaces:
  java.sql.Driver

Direct Known Subclasses:
  Driver, NonRegisteringReplicationDriver

    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")

### 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`
  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
  See Also:
    `Driver.acceptsURL(java.lang.String)`

### 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 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`
  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 isnt us
  Throws:
    `java.sql.SQLException` - if a database access error occurs
  See Also:
    `Driver.connect(java.lang.String, java.util.Properties)`

### connectReplicationConnection

    protected java.sql.Connection connectReplicationConnection(java.lang.String url,
                                                               java.util.Properties info)
                                                        throws java.sql.SQLException

  Throws:
    `java.sql.SQLException`

  Parameters:
    `props` - the Properties to look for the database property.
  Returns:
    the database name.

### getMajorVersion

    public int getMajorVersion()

  Gets the drivers major version number

  Specified by:
    `getMajorVersion` in interface `java.sql.Driver`
  Returns:
    the drivers major version number

### getMinorVersion

    public int getMinorVersion()

  Get the drivers minor version number

  Specified by:
    `getMinorVersion` in interface `java.sql.Driver`
  Returns:
    the drivers minor version number

### 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`
  Parameters:
    `url` - the Url of the database to connect to
    `info` - a proposed list of tag/value pairs that will be sent on connect open.
  Returns:
    An array of DriverPropertyInfo objects describing possible properties. This array may be an empty array if no properties are required
  Throws:
    `java.sql.SQLException` - if a database-access error occurs

  Specified by:
    `jdbcCompliant` in interface `java.sql.Driver`
  Returns:
    is this driver JDBC compliant?

  Throws:
    `java.sql.SQLException`
