public class Series

extends java.lang.Object

implements java.lang.Cloneable, java.io.Serializable

Base class representing a data series. Subclasses are left to implement the actual data structures.

The series has two properties ("Name" and "Description") for which you can register a PropertyChangeListener.

You can also register a SeriesChangeListener to receive notification of changes to the series data.

Constructor Detail

Series

protected Series(java.lang.String name)

Constructs a series.

Parameters:

name - The series name.

Series

protected Series(java.lang.String name,
                 java.lang.String description)

Constructs a series.

Parameters:

name - the series name.

description - the series description (null permitted).

Method Detail

getName

public java.lang.String getName()

Returns the name of the series.

Returns:

the name of the series.

setName

public void setName(java.lang.String name)

Sets the name of the series.

Parameters:

name - the name.

getDescription

public java.lang.String getDescription()

Returns a description of the series.

Returns:

A description of the series (possibly null).

setDescription

public void setDescription(java.lang.String description)

Sets the description of the series.

Parameters:

description - the description (null permitted).

clone

public java.lang.Object clone()

Returns a clone of the series.

Notes: 1. No need to clone the name or description, since String object is immutable. 2. We set the listener list to empty, since the listeners did not register with the clone. 3. Same applies to the PropertyChangeSupport instance.

Overrides:

clone in class java.lang.Object

Returns:

a clone of the series.

addChangeListener

public void addChangeListener(SeriesChangeListener listener)

Registers an object with this series, to receive notification whenever the series changes.

Objects being registered must implement the SeriesChangeListener interface.

Parameters:

listener - The object to register.

removeChangeListener

public void removeChangeListener(SeriesChangeListener listener)

Deregisters an object, so that it not longer receives notification whenever the series changes.

Call this method when an object no longer needs to be notified of changes to the series.

Parameters:

listener - The object to deregister.

fireSeriesChanged

public void fireSeriesChanged()

General method for signalling to registered listeners that the series has been changed.

notifyListeners

protected void notifyListeners(SeriesChangeEvent event)

Sends a change event to all registered listeners.

Parameters:

event - Contains information about the event that triggered the notification.

addPropertyChangeListener

public void addPropertyChangeListener(java.beans.PropertyChangeListener listener)

Adds a property change listener to the series.

Parameters:

listener - The listener.

removePropertyChangeListener

public void removePropertyChangeListener(java.beans.PropertyChangeListener listener)

Removes a property change listener from the series.

Parameters:

listener - The listener.

firePropertyChange

protected void firePropertyChange(java.lang.String property,
                                  java.lang.Object oldValue,
                                  java.lang.Object newValue)

Fires a property change event.

Parameters:
