51 * This is the model used by the history browser.
52 *
53 * The model state consists of the following elements:
54 * <ul>
55 * <li>the {@link History} of a specific {@link OsmPrimitive}</li>
56 * <li>a dedicated version in this {@link History} called the {@link PointInTimeType#REFERENCE_POINT_IN_TIME}</li>
57 * <li>another version in this {@link History} called the {@link PointInTimeType#CURRENT_POINT_IN_TIME}</li>
58 * </ul>
59 * {@link HistoryBrowser} always compares the {@link PointInTimeType#REFERENCE_POINT_IN_TIME} with the
60 * {@link PointInTimeType#CURRENT_POINT_IN_TIME}.
61
62 * This model provides various {@link TableModel}s for {@link JTable}s used in {@link HistoryBrowser}, for
63 * instance:
64 * <ul>
65 * <li>{@link #getTagTableModel(PointInTimeType)} replies a {@link TableModel} for the tags of either of
66 * the two selected versions</li>
67 * <li>{@link #getNodeListTableModel(PointInTimeType)} replies a {@link TableModel} for the list of nodes of
68 * the two selected versions (if the current history provides information about a {@link Way}</li>
69 * <li> {@link #getRelationMemberTableModel(PointInTimeType)} replies a {@link TableModel} for the list of relation
70 * members of the two selected versions (if the current history provides information about a {@link Relation}</li>
71 * </ul>
