Interface DriverAction
public interface DriverAction
An interface that must be implemented when a Driver wants to be notified by DriverManager
.
A DriverAction
implementation is not intended to be used directly by applications. A JDBC Driver may choose to create its DriverAction
implementation 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 DriverManager
which DriverAction
implementation to call when the JDBC driver is de-registered.

- 1.8

Method Detail
deregister
void deregister()
Method called by DriverManager.deregisterDriver(Driver) to notify the JDBC driver that it was de-registered.
The deregister
method is intended only to be used by JDBC Drivers and not by applications. JDBC drivers are recommended to not implement DriverAction
in a public class. If there are active connections to the database at the time that the deregister
method 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 Driver
methods or throw a SQLException
. Consult your JDBC driver's documentation for additional information on its behavior.
