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).
getDataset
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
).
