Interface Driver
This interface specifies a mechanism for accessing a JDBC database
driver. When the class implementing this method is loaded, it should
register an instance of itself with the
DriverManager in
a static initializer.
Because the
DriverManager might attempt to use several
drivers to find one that can connect to the requested database,
this driver should not cause large numbers of classes and code to
be loaded. If another driver is the one that ends up performing the
request, any loading done by this driver would be wasted.
acceptsURL
public boolean acceptsURL(String url)
throws SQLException This method tests whether or not the driver believes it can connect to
the specified database. The driver should only test whether it
understands and accepts the URL. It should not necessarily attempt to
probe the database for a connection.
url - The database URL string.
true if the drivers can connect to the database,
false otherwise.
connect
public Connection connect(String url,
Properties properties)
throws SQLException This method connects to the specified database using the connection
properties supplied. If the driver does not understand the database
URL, it should return null instead of throwing an
exception since the DriverManager will probe a driver
in this manner.
url - The URL string for this connection.properties - The list of database connection properties.
- A
Connection object for the newly established
connection, or null if the URL is not understood.
getMajorVersion
public int getMajorVersion()
This method returns the major version number of the driver.
- The major version number of the driver.
getMinorVersion
public int getMinorVersion()
This method returns the minor version number of the driver.
- The minor version number of the driver.
getPropertyInfo
public DriverPropertyInfo[] getPropertyInfo(String url,
Properties properties)
throws SQLException This method returns an array of possible properties that could be
used to connect to the specified database.
url - The URL string of the database to connect to.properties - The list of properties the caller is planning to use
to connect to the database.
- A list of possible additional properties for a connection to this
database. This list may be empty.
jdbcCompliant
public boolean jdbcCompliant()
This method tests whether or not the driver is JDBC compliant. This
method should only return true if the driver has been
certified as JDBC compliant.
true if the driver has been certified JDBC compliant,
false otherwise.
