/**
 * The {@code AccessibleTableModelChange} interface describes a change to the
 * table model. The attributes of the model change can be obtained by the
 * following methods:
 * <ul>
 *   <li>{@code public int getType();}
 *   <li>{@code public int getFirstRow();}
 *   <li>{@code public int getLastRow();}
 *   <li>{@code public int getFirstColumn();}
 *   <li>{@code public int getLastColumn();}
 * </ul>
 * The model change type returned by getType() will be one of:
 * <ul>
 *   <li>{@code INSERT} - one or more rows and/or columns have been inserted
 *   <li>{@code UPDATE} - some of the table data has changed
 *   <li>{@code 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
