Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`default java.awt.geom.Area`	`getDataSourceArea()`	Returns the total area of downloaded data (the "yellow rectangles").

- Method Detail
  - getDataSources
```
java.util.Collection<DataSource> getDataSources()
```
    Returns the collection of data sources.
    
    Returns:
    
    the collection of data sources.
  - getDataSourceArea
```
default java.awt.geom.Area getDataSourceArea()
```
    Returns the total area of downloaded data (the "yellow rectangles").
    
    Returns:
    
    Area object encompassing downloaded data.
  - getDataSourceBounds
```
default java.util.List<Bounds> getDataSourceBounds()
```
    Replies the list of data source bounds.
    
    Dataset maintains a list of data sources which have been merged into the data set. Each of these sources can optionally declare a bounding box of the data it supplied to the dataset.
    
    This method replies the list of defined (non null) bounding boxes.
    
    Returns:
    
    the list of data source bounds. An empty list, if no non-null data source bounds are defined.
