|
|
* This class keeps the selection of a {@link Dataset} (based on feature |
| 37 |
|
|
* attributes) synchronized with the {@link StyledLayerSelectionModel} of a layer. |
| 38 |
|
|
* This is done by implementing: |
| 39 |
|
|
* <ul> |
| 40 |
|
|
* <li>a {@link PropertyChangeListener} which listens to the |
| 41 |
|
|
* {@link StyledLayerSelectionModel} and accordingly changes the {@link SelectionRenderer} |
| 42 |
|
|
* selection</li> |
| 43 |
|
|
* <li>a {@link DatasetSelectionModel} which listens to the {@link SelectionRenderer} and |
| 44 |
|
|
* accordingly changes the {@link StyledLayerSelectionModel} selection</li> |
| 45 |
|
|
* </ul> |
| 46 |
|
|
* After creating, the instance of this synchronizer must be added as listener |
| 47 |
|
|
* to both, the {@link StyledLayerSelectionModel} and the chart's |
| 48 |
mojays |
131 |
* {@link DatasetSelectionModel} (e.g. the renderer). |
