Fields Summary
private static final long	oldSerialVersionUID
private static final long	newSerialVersionUID
private static final ObjectStreamField[]	oldSerialPersistentFields
private static final ObjectStreamField[]	newSerialPersistentFields
private static final long	serialVersionUID
private static final ObjectStreamField[]	serialPersistentFields
private static boolean	compat
private String	type
private long	sequenceNumber
private long	timeStamp

protected Object	source This field hides the {@link EventObject#source} field in the parent class to make it non-transient and therefore part of the serialized form.

Constructors Summary
public Notification(String type, Object source, long sequenceNumber) Creates a Notification object. The notification timeStamp is set to the current date. param type The notification type. param source The notification source. param sequenceNumber The notification sequence number within the source object. super (source) ; this.source = source; this.type = type; this.sequenceNumber = sequenceNumber ; this.timeStamp = (new java.util.Date()).getTime() ;
public Notification(String type, Object source, long sequenceNumber, String message) Creates a Notification object. The notification timeStamp is set to the current date. param type The notification type. param source The notification source. param sequenceNumber The notification sequence number within the source object. param message The detailed message. super (source) ; this.source = source; this.type = type; this.sequenceNumber = sequenceNumber ; this.timeStamp = (new java.util.Date()).getTime() ; this.message = message ;
public Notification(String type, Object source, long sequenceNumber, long timeStamp) Creates a Notification object. param type The notification type. param source The notification source. param sequenceNumber The notification sequence number within the source object. param timeStamp The notification emission date. super (source) ; this.source = source; this.type = type ; this.sequenceNumber = sequenceNumber ; this.timeStamp = timeStamp ;
public Notification(String type, Object source, long sequenceNumber, long timeStamp, String message) Creates a Notification object. param type The notification type. param source The notification source. param sequenceNumber The notification sequence number within the source object. param timeStamp The notification emission date. param message The detailed message. super (source) ; this.source = source; this.type = type ; this.sequenceNumber = sequenceNumber ; this.timeStamp = timeStamp ; this.message = message ;

Methods Summary
public java.lang.String	getMessage() Get the notification message. return The message string of this notification object. It contains in a string, which could be the explanation of the notification for displaying to a user return message ;
public long	getSequenceNumber() Get the notification sequence number. return The notification sequence number within the source object. It's a serial number identifying a particular instance of notification in the context of the notification source. The notification model does not assume that notifications will be received in the same order that they are sent. The sequence number helps listeners to sort received notifications. see #setSequenceNumber return sequenceNumber ;
public long	getTimeStamp() Get the notification timestamp. return The notification timestamp. see #setTimeStamp return timeStamp ;
public java.lang.String	getType() Get the notification type. return The notification type. It's a string expressed in a dot notation similar to Java properties. An example of a notification type is network.alarm.router . return type ;
public java.lang.Object	getUserData() Get the user data. return The user data object. It is used for whatever data the notification source wishes to communicate to its consumers. see #setUserData return userData ;
private void	readObject(java.io.ObjectInputStream in) Deserializes a {@link Notification} from an {@link ObjectInputStream}. // New serial form ignores extra field "sourceObjectName" in.defaultReadObject(); super.source = source;
public void	setSequenceNumber(long sequenceNumber) Set the notification sequence number. param sequenceNumber The notification sequence number within the source object. It is a serial number identifying a particular instance of notification in the context of the notification source. see #getSequenceNumber this.sequenceNumber = sequenceNumber;
public void	setSource(java.lang.Object source) Sets the source. param source the new source for this object. see EventObject#getSource super.source = source; this.source = source;
public void	setTimeStamp(long timeStamp) Set the notification timestamp. param timeStamp The notification timestamp. It indicates when the notification was generated. see #getTimeStamp this.timeStamp = timeStamp;
public void	setUserData(java.lang.Object userData) Set the user data. param userData The user data object. It is used for whatever data the notification source wishes to communicate to its consumers. see #getUserData this.userData = userData ;
public java.lang.String	toString() Returns a String representation of this notification. return A String representation of this notification. return super.toString()+"[type="+type+"][message="+message+"]";
private void	writeObject(java.io.ObjectOutputStream out) Serializes a {@link Notification} to an {@link ObjectOutputStream}. if (compat) { // Serializes this instance in the old serial form // ObjectOutputStream.PutField fields = out.putFields(); fields.put("type", type); fields.put("sequenceNumber", sequenceNumber); fields.put("timeStamp", timeStamp); fields.put("userData", userData); fields.put("message", message); fields.put("source", source); out.writeFields(); } else { // Serializes this instance in the new serial form // out.defaultWriteObject(); }
