040 * <p>
041 * IndexShapeFile is an application that can be used to index an ESRI ShapeFiles(tm). It indexes
042 * both the geometry and the alphanumeric attributes
043 * </p>
044 *
045 * <p>
046 * The application shows a file chooser with which the user can select a file. When a file is
047 * choosen the application opens it and shows the attributes. The user can now select the attributes
048 * that has to be indexed. Already indexed attributes are already selected and can be deselected.
049 * For alphanumeric attributes the user can indicate if the attribute is unique or not.
050 * </p>
051 *
052 * <p>
053 * After selecting the attributes the application creates the needed indexes and loops over all the
054 * features in the shape file. For every feature the application inserts the attributes in the right
055 * index. After looping over the features the application closes the shapefile and the created
056 * indexes and removes the indexes that are no longer needed (eg. the index for the attributes that
057 * are deselected).
058 * </p>
059 *
060 * <p>
061 * It is not possible to transform a unique index to a non-unique index or back.
062 * </p>
