JTable, RowFilter and RowFilter.Entry

I see no unexpected result.

  1. The first predicate is straightforward; it includes the intersection of two overlapping sets, with the row having Value 13 as the only member.

    return ((Number) entry.getValue(1)).intValue() > 10
        & ((Number) entry.getValue(1)).intValue() < 50;
    
  2. The second predicate is the union of two overlapping sets, with all rows included.

    return ((Number) entry.getValue(1)).intValue() > 10 |
        ((Number) entry.getValue(1)).intValue() < 50;
    
  3. The third predicate is the complement of the first, with the row having Value 13 alternately included and excluded.

    return ((Number) entry.getValue(1)).intValue() > 10 != 
        ((Number) entry.getValue(1)).intValue() < 50;
    

Addendum: Regarding RowFilter.Entry, I found it helpful to examine how the and, or and not factories use the extra index parameter defined in the private class RowFilter.GeneralFilter; each subclass invokes the parent's implementation of include() for each filter supplied in the constructor. In contrast, the date, number and regex factories do not; instead, each relies on predicates available to the underlying type.

Addendum: As a concrete example, select two model dates, e.g. the first and penultimate.

Date d1 = (Date) model.getValueAt(0, 3);
Date d2 = (Date) model.getValueAt(model.getRowCount() - 2, 3);

Create two filters that bracket the chosen dates.

RowFilter<TableModel, Integer> low = 
    RowFilter.dateFilter(RowFilter.ComparisonType.AFTER, d1, 3);
RowFilter<TableModel, Integer> high = 
    RowFilter.dateFilter(RowFilter.ComparisonType.BEFORE, d2, 3);

Combine them in an andFilter.

List<RowFilter<TableModel, Integer>> filters = Arrays.asList(low, high);
final RowFilter<TableModel, Integer> filter = RowFilter.andFilter(filters);

The result selects rows between, but excluding, d1 and d2.
