> This pattern exists a lot w/ some minor fluxuations in copy/paste variation...
> {code}
> @Override
> public SortField getSortField(SchemaField field, boolean top) {
> field.checkSortability();
> Object missingValue = null;
> boolean sortMissingLast = field.sortMissingLast();
> boolean sortMissingFirst = field.sortMissingFirst();
> if (sortMissingLast) {
> missingValue = top ? SOMECLASS.MIN_VALUE : SOMECLASS.MAX_VALUE;
> } else if (sortMissingFirst) {
> missingValue = top ? SOMECLASS.MAX_VALUE : SOMECLASS.MIN_VALUE;
> }
> SortField sf = new SortField(field.getName(), SortField.Type.SOMETYPE,
> top);
> sf.setMissingValue(missingValue);
> return sf;
> }
> {code}
> We should refactor it into a helper method along the lines of...
> {code}
> @Override
> public static SortField getSortField(SchemaField field, boolean top,
> SortField.Type sortType,
> Object missingLow, Object missingHigh)
> {
> field.checkSortability();
> Object missingValue = null;
> boolean sortMissingLast = field.sortMissingLast();
> boolean sortMissingFirst = field.sortMissingFirst();
> if (sortMissingLast) {
> missingValue = top ? missingLow : missingHigh;

> missingValue = top ? missingHigh : missingLow;
> }
> SortField sf = new SortField(field.getName(), sortType, top);
> sf.setMissingValue(missingValue);
> return sf;
> }
> {code}
> So it can be re-used via...
> {code}
> @Override
> public SortField getSortField(SchemaField field, boolean top) {
> return getSortField(field, top, SortField.Type.SOMETIME,
> SOMECLASS.MIN_VALUE, SOMECLASS.MAX_VALUE);
