50 * ListMergeModel is a model for interactively comparing and merging two list of entries
51 * of type T. It maintains three lists of entries of type T:
52 * <ol>
53 * <li>the list of <em>my</em> entries</li>
54 * <li>the list of <em>their</em> entries</li>
55 * <li>the list of <em>merged</em> entries</li>
56 * </ol>
57 *
58 * A ListMergeModel is a factory for three {@link TableModel}s and three {@link ListSelectionModel}s:
59 * <ol>
60 * <li>the table model and the list selection for for a {@link JTable} which shows my entries.
61 * See {@link #getMyTableModel()} and {@link AbstractListMergeModel#getMySelectionModel()}</li>
62 * <li>dito for their entries and merged entries</li>
63 * </ol>
64 *
65 * A ListMergeModel can be ''frozen''. If it's frozen, it doesn't accept additional merge
66 * decisions. {@link PropertyChangeListener}s can register for property value changes of
67 * {@link #FROZEN_PROP}.
68 *
69 * ListMergeModel is an abstract class. Three methods have to be implemented by subclasses:
70 * <ul>
71 * <li>{@link AbstractListMergeModel#cloneEntryForMergedList} - clones an entry of type T</li>
72 * <li>{@link AbstractListMergeModel#isEqualEntry} - checks whether two entries are equals </li>
73 * <li>{@link AbstractListMergeModel#setValueAt(DefaultTableModel, Object, int, int)} - handles values edited in
74 * a JTable, dispatched from {@link TableModel#setValueAt(Object, int, int)} </li>
75 * </ul>
76 * A ListMergeModel is used in combination with a {@link AbstractListMerger}.
77 *
78 * @param <T> the type of the list entries
79 * @param <C> the type of conflict resolution command
80 * @see AbstractListMerger
81 * @see PairTable For the table displaying this model
