Class DatasetChangeEvent

public DatasetChangeEvent(Object source,
                          Dataset dataset)

Constructs a new event. The source is either the dataset or the Plot class. The dataset can be null (in this case the source will be the Plot class).

Parameters:

source - the source of the event.

dataset - the dataset that generated the event (null permitted).

public Dataset getDataset()

Returns the dataset that generated the event. Note that the dataset may be null since adding a null dataset to a plot will generated a change event.

Returns:

The dataset (possibly null).
