java.lang.Objectorg.jfree.data.general.Series
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 Summary | |
protected |
Series(java.lang.Comparable key)
Creates a new series. |
protected |
Series(java.lang.Comparable key,
java.lang.String description)
Constructs a series. |
Method Summary | |
void |
addChangeListener(SeriesChangeListener listener)
Registers an object with this series, to receive notification whenever the series changes. |
void |
addPropertyChangeListener(java.beans.PropertyChangeListener listener)
Adds a property change listener to the series. |
java.lang.Object |
clone()
Returns a clone of the series. |
boolean |
equals(java.lang.Object obj)
Tests the series for equality with another object. |
protected void |
firePropertyChange(java.lang.String property,
java.lang.Object oldValue,
java.lang.Object newValue)
Fires a property change event. |
void |
fireSeriesChanged()
General method for signalling to registered listeners that the series has been changed. |
java.lang.String |
getDescription()
Returns a description of the series. |
java.lang.Comparable |
getKey()
Returns the key for the series. |
boolean |
getNotify()
Returns the flag that controls whether or not change events are sent to registered listeners. |
int |
hashCode()
Returns a hash code. |
protected void |
notifyListeners(SeriesChangeEvent event)
Sends a change event to all registered listeners. |
void |
removeChangeListener(SeriesChangeListener listener)
Deregisters an object, so that it not longer receives notification whenever the series changes. |
void |
removePropertyChangeListener(java.beans.PropertyChangeListener listener)
Removes a property change listener from the series. |
void |
setDescription(java.lang.String description)
Sets the description of the series. |
void |
setKey(java.lang.Comparable key)
Sets the key for the series. |
void |
setNotify(boolean notify)
Sets the flag that controls whether or not change events are sent to registered listeners. |
