Interface Connector

All Superinterfaces:

java.lang.Cloneable, java.io.Serializable

All Known Implementing Classes:

DataSourceConnector, DefaultConnector, JNDIConnector

public interface Connector

extends java.io.Serializable, java.lang.Cloneable

Purpose: Define an interface for supplying TopLink with a Connection to a JDBC database.

Description: This interface defines the methods to be implemented that allow TopLink to acquire a Connection to a JDBC database. There are only 2 methods that need to be implemented:

java.sql.Connection connect(java.util.Properties properties)
void toString(java.io.PrintWriter writer)

Once these methods have been implemented, an instance of the new Connector can be passed to a JDBCLogin at startup. For example:

session.getLogin().setConnector(new FooConnector());
session.login();

Since:

TOPLink/Java 2.1

Method Summary

java.lang.Object	clone() PUBLIC: Must be cloneable.
java.sql.Connection	connect(java.util.Properties properties) PUBLIC: Connect with the specified properties and return the Connection.
void	toString(java.io.PrintWriter writer) PUBLIC: Print something useful on the log.

Method Detail

clone

public java.lang.Object clone()

PUBLIC: Must be cloneable.

connect

public java.sql.Connection connect(java.util.Properties properties)

PUBLIC: Connect with the specified properties and return the Connection. The properties are driver-specific; but usually contain the "user" and "password". Additional properties can be built by using JDBCLogin.setProperty(String propertyName, Object propertyValue).

Returns:

java.sql.Connection

toString

public void toString(java.io.PrintWriter writer)

PUBLIC: Print something useful on the log. This information will be displayed on the TopLink log (by default System.out) at login. See the other implementations of this method for examples.
