java.lang.Object
- uk.ac.starlink.topcat.plot.PoolStyleSet

All Implemented Interfaces:

MutableStyleSet, uk.ac.starlink.ttools.plot.StyleSet
```
public class PoolStyleSet
extends java.lang.Object
implements MutableStyleSet
```
StyleSet which obtains styles from a base StyleSet, but only dispenses ones which are not already used. A global list of used indices, which is shared with other instances of this class, ensures that markers are not shared between them. Since this also implements MutableStyleSet, individual styles can be overwritten.
