 public class JMXConnectionNotification extends Notification Notification emitted when a client connection is opened or closed or when notifications are lost. These notifications are sent by connector servers (instances of JMXConnectorServer) and by connector clients (instances ofJMXConnector). For certain connectors, a session can consist of a sequence of connections. Connection-opened and connection-closed notifications will be sent for each one.The notification type is one of the following: Type Meaning jmx.remote.connection.openedA new client connection has been opened. jmx.remote.connection.closedA client connection has been closed. jmx.remote.connection.failedA client connection has failed unexpectedly. jmx.remote.connection.notifs.lostA client connection has potentially lost notifications. This notification only appears on the client side. The timeStampof the notification is a time value (consistent withSystem.currentTimeMillis()) indicating when the notification was constructed.- Since:

Constructor Detail- 
JMXConnectionNotificationpublic JMXConnectionNotification(String type, Object source, String connectionId, long sequenceNumber, String message, Object userData) Constructs a new connection notification. Thesourceof the notification depends on whether it is being sent by a connector server or a connector client:- For a connector server, if it is registered in an MBean
 server, the source is the ObjectNameunder which it is registered. Otherwise, it is a reference to the connector server object itself, an instance of a subclass ofJMXConnectorServer.
- For a connector client, the source is a reference to the
 connector client object, an instance of a class implementing
 JMXConnector.
 - Parameters:
- type- the type of the notification. This is usually one of the constants- OPENED,- CLOSED,- FAILED,- NOTIFS_LOST. It is not an error for it to be a different string.
- source- the connector server or client emitting the notification.
- connectionId- the ID of the connection within its connector server.
- sequenceNumber- a non-negative integer. It is expected but not required that this number will be greater than any previous- sequenceNumberin a notification from this source.
- message- an unspecified text message, typically containing a human-readable description of the event. Can be null.
- userData- an object whose type and meaning is defined by the connector server. Can be null.
- Throws:
- NullPointerException- if- type,- source, or- connectionIdis null.
- IllegalArgumentException- if- sequenceNumberis negative.
 
- For a connector server, if it is registered in an MBean
 server, the source is the
