/**

 * The AccessibleTableModelChange interface describes a change to

 * the table model.  The attributes of the model change can be

 * obtained by the following methods:

 * <ul>

 * <li> public int getType()

 * <li> public int getFirstRow();

 * <li> public int getLastRow();

 * <li> public int getFirstColumn();

 * <li> public int getLastColumn();

 * </ul>

 * The model change type returned by getType() will be one of:

 * <ul>

 * <li> INSERT - one or more rows and/or columns have been inserted

 * <li> UPDATE - some of the table data has changed

 * <li> DELETE - one or more rows and/or columns have been deleted

 * </ul>

 * The affected area of the table can be determined by the other

 * four methods which specify ranges of rows and columns
