sonification.dataimport.visbards_resourcetoolkit.model
Class DefaultDatasetContainer

java.lang.Object
  sonification.dataimport.visbards_resourcetoolkit.model.DefaultDatasetContainer

All Implemented Interfaces:

java.io.Serializable, CategoryPoolListener, DatasetContainer, DatasetListener, RangeModelListener, PseudoCategoryListener

public class DefaultDatasetContainer
extends java.lang.Object
implements DatasetContainer, DatasetListener, CategoryPoolListener, PseudoCategoryListener, RangeModelListener, java.io.Serializable

This unit keeps a collection of datasets and their default properties. It is able to inform it's listeners about additions/removals of datasets. It also servers as a link to the 3d universe, as it attaches and detatches datasets from it.
