public class LargeFeatureSelection 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.

    • LargeFeatureSelection

      public LargeFeatureSelection()
      Constructor used by the persistence manager. Don't use directly. After to invoke this method, the persistence manager calls the the method loadFromState(PersistentState) to set the values of the internal attributes that this class needs to work.
