示例1: setValueAt

import org.opengis.filter.sort.SortOrder; //导入依赖的package包/类
@Override
public void setValueAt(Object aValue, int row, int column) {
    SortBy obj = dataList.get(row);

    switch (column) {
    case 0:
        break;
    case COL_SORT_ORDER: {
        Boolean b = (Boolean) aValue;

        SortOrder sortOrder = b.booleanValue() ? SortOrder.ASCENDING : SortOrder.DESCENDING;
        ((SortByImpl) obj).setSortOrder(sortOrder);

        fireTableCellUpdated(row, column);

        if (parentObj != null) {
            parentObj.sortOrderUpdated();
        }
