Class ArrayTableModel<R>

java.lang.Object

javax.swing.table.AbstractTableModel

uk.ac.starlink.util.gui.ArrayTableModel<R>

All Implemented Interfaces:

Serializable, TableModel

Direct Known Subclasses:

ResourceTableModel

public class ArrayTableModel<R>
extends AbstractTableModel

TableModel which contains its data as an array of objects, one per row. The ArrayTableSorter class can be used in conjunction with this class to provide tables which can be sorted by clicking on column headers. The model works by having an array of column objects which know how to interrogate the array of data objects in such a way as to return cell values. The implementation of the column and data item objects is therefore interlinked.
