Examples of javax.sql.RowSetMetaData

javax.sql.RowSetMetaData
An interface which provides facilities for getting information about the columns in a RowSet.
RowSetMetaData extends ResultSetMetaData, adding new operations for carrying out value sets.
Application code would not mormally call this interface directly. It would be called internally when RowSet.execute is called.

                setMetaData(copyMetaData(rsmd));
            }
        } else {
            int colCount = getMetaData().getColumnCount()
                    + rsmd.getColumnCount() - 1;
            RowSetMetaData rowSetMetaData = new RowSetMetaDataImpl();
            rowSetMetaData.setColumnCount(colCount);
            for (int i = 1; i <= getMetaData().getColumnCount(); i++) {
                doCopyMetaData(rowSetMetaData, i, getMetaData(), i);
                if (i == matchColIndexs.get(0).intValue()) {
                    rowSetMetaData.setColumnName(i, MERGED_COLUMN_NAME);
