Constructors

public JMXConnectionNotification (String type, Object source, String connectionId, long sequenceNumber, String message, Object userData)

Constructs a new connection notification.

Constructs a new connection notification. The source of 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 ObjectName under which it is
registered. Otherwise, it is a reference to the connector
server object itself, an instance of a subclass of JMXConnectorServer.
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 {@link #OPENED}, {@link #CLOSED}, {@link #FAILED}, {@link #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 sequenceNumber in 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 connectionId is null.
- IllegalArgumentException - if sequenceNumber is negative.
