Direct Known Subclasses:

ConfigurableFeatureTableModel

public class FeatureTableModel
extends AbstractTableModel
implements ComplexObserver

TableModel to access data of Features. This table model can't handle a FeatureSet with more than Integer.MAX_VALUE elements. In that case, only the first Integer.MAX_VALUE elements will be shown.
