Package Summary Overview Summary

### class:JMXConnectionNotification [NONE]
All Implemented Interfaces: `Serializable` 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 of `JMXConnector`). 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:
JMXConnectionNotification Types
Type | Meaning
--- | ---
`jmx.remote.connection.opened` | A new client connection has been opened.
`jmx.remote.connection.closed` | A client connection has been closed.
`jmx.remote.connection.failed` | A client connection has failed unexpectedly.
`jmx.remote.connection.notifs.lost` | A client connection has potentially lost notifications. This notification only appears on the client side.
The `timeStamp` of the notification is a time value (consistent with `System.currentTimeMillis()`) indicating when the notification was constructed. Since: 1.5 See Also: Serialized Form

### field:OPENED [NONE]
### OPENED public static final String OPENED Notification type string for a connection-opened notification. See Also: Constant Field Values

### field:CLOSED [NONE]
### CLOSED public static final String CLOSED Notification type string for a connection-closed notification. See Also: Constant Field Values

### field:FAILED [NONE]
### FAILED public static final String FAILED Notification type string for a connection-failed notification. See Also: Constant Field Values

### field:NOTIFS_LOST [NONE]
### NOTIFS_LOST public static final String NOTIFS_LOST Notification type string for a connection that has possibly lost notifications. See Also: Constant Field Values

### constructor:JMXConnectionNotification(java.lang.String,java.lang.Object,java.lang.String,long,java.lang.String,java.lang.Object) [NONE]
### JMXConnectionNotification public JMXConnectionNotification (String type, Object source, String connectionId, long sequenceNumber, String message, Object userData) 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 `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 `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.

### method:getConnectionId() [NONE]
### getConnectionId public String getConnectionId() The connection ID to which this notification pertains. Returns: the connection ID.
