Class GenericConnector

java.lang.Object
  javax.management.remote.generic.GenericConnector

All Implemented Interfaces:

JMXConnector

Direct Known Subclasses:

JMXMPConnector

public class GenericConnector
extends Object
implements JMXConnector

A client connection to a remote JMX API server. This class can use a MessageConnection object to specify the transport for communicating with the server.

User code does not usually instantiate this class. Instead, a JMXConnectorProvider should be added to the JMXConnectorFactory so that users can implicitly instantiate the GenericConnector (or a subclass of it) through the JMXServiceURL provided when connecting.

The specific connector protocol to be used by an instance of this class is specified by attributes in the Map passed to the constructor or the connect method. The attribute MESSAGE_CONNECTION is the standard way to define the transport. An implementation can recognize other attributes to define the transport differently.

Field Summary

static String	MESSAGE_CONNECTION Name of the attribute that specifies how this connector sends messages to its connector server.
static String	OBJECT_WRAPPING Name of the attribute that specifies the object wrapping for parameters whose deserialization requires special treatment.

Field Detail

OBJECT_WRAPPING

public static final String OBJECT_WRAPPING

sendNotification

protected void sendNotification(Notification n)

Send a notification to the connection listeners. The notification will be sent to every listener added with addConnectionNotificationListener that was not subsequently removed by a removeConnectionNotificationListener, provided the corresponding NotificationFilter matches.

Parameters:

n - the notification to send. This will usually be a JMXConnectionNotification, but an implementation can send other notifications as well.
