Constructor Details

AbstractSeriesDataset

protected AbstractSeriesDataset()
Creates a new dataset.

Method Details

getSeriesCount

public abstract int getSeriesCount()
Returns the number of series in the dataset.
Specified by:
getSeriesCount in interface SeriesDataset
Returns:
The series count.

getSeriesKey

public abstract Comparable getSeriesKey(int series)
Returns the key for a series.

If series is not within the specified range, the implementing method should throw an IndexOutOfBoundsException (preferred) or an IllegalArgumentException.

Specified by:
getSeriesKey in interface SeriesDataset
Parameters:
series - the series index (in the range 0 to getSeriesCount() - 1).
Returns:
The series key.

indexOf

public int indexOf(Comparable seriesKey)
Returns the index of the named series, or -1.
Specified by:
indexOf in interface SeriesDataset
Parameters:
seriesKey - the series key (null permitted).
Returns:
The index.

seriesChanged

public void seriesChanged(SeriesChangeEvent event)
Called when a series belonging to the dataset changes.
Specified by:
seriesChanged in interface SeriesChangeListener
Parameters:
event - information about the change.
