Interface Connector

All Superinterfaces:

Cloneable, Serializable

All Known Implementing Classes:

DefaultConnector, DirectConnector, EISConnectionSpec, JNDIConnector, OracleOCIProxyConnector

public interface Connector
extends Serializable, 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();

Method Summary

Modifier and Type	Method and Description
Object	clone() INTERNAL: Must be cloneable.
Connection	connect(Properties properties, Session session) INTERNAL: Connect with the specified properties and return the Connection.
String	getConnectionDetails() INTERNAL: Provide the details of my connection information.
void	toString(PrintWriter writer) INTERNAL: Print something useful on the log.

Method Detail

clone

Object clone()

INTERNAL: Must be cloneable.

connect

Connection connect(Properties properties,
                   Session session)

INTERNAL: 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

void toString(PrintWriter writer)

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

getConnectionDetails

String getConnectionDetails()

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

Returns:

java.lang.String
