Class 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.
