public class DefaultFeatureSelection extends AbstractFeatureSet implements org.gvsig.fmap.dal.feature.FeatureSelection
Default implementation of the FeatureSelection interface. Internally, only FeatureReference values are stored. This implementation performs better if used with the selection related methods: select, deselect and isSelected ones.
