Interface Connector

All Superinterfaces:

java.lang.Cloneable, java.io.Serializable

All Known Implementing Classes:

DefaultConnector, EISConnectionSpec, 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.
java.lang.String	getConnectionDetails() PUBLIC: Provide the details of my connection information.
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.

getConnectionDetails

public java.lang.String getConnectionDetails()

PUBLIC: Provide the details of my connection information. This is primarily for JMX runtime services.

Returns:

java.lang.String
