public interface DriverActionAn interface that must be implemented when a Driver wants to be notified by
DriverActionimplementation is not intended to be used directly by applications. A JDBC Driver may choose to create its
DriverActionimplementation in a private class to avoid it being called directly.
The JDBC driver's static initialization block must call DriverManager.registerDriver(java.sql.Driver, java.sql.DriverAction) in order to inform
DriverActionimplementation to call when the JDBC driver is de-registered.
void deregister()Method called by DriverManager.deregisterDriver(Driver) to notify the JDBC driver that it was de-registered.
deregistermethod is intended only to be used by JDBC Drivers and not by applications. JDBC drivers are recommended to not implement
DriverActionin a public class. If there are active connections to the database at the time that the
deregistermethod is called, it is implementation specific as to whether the connections are closed or allowed to continue. Once this method is called, it is implementation specific as to whether the driver may limit the ability to create new connections to the database, invoke other
Drivermethods or throw a
SQLException. Consult your JDBC driver's documentation for additional information on its behavior.
