  - getFieldsWithScales
```
public abstract Set<Drawable.NameAndRange> getFieldsWithScales()
```
    Returns:
    
    A list of all the fields used in this image layer, and their appropriate scale ranges. If there is NO scale range there can be NO data field and vice versa - i.e. a Drawable.NameAndRange object must have all non-null fields. If the layer doesn't depend on any data, this should return an empty set. It should never return null.
