### Question:
BitMapFilterEvaluator { public ConciseSet evaluate(TupleFilter filter) { if (filter == null) return null; if (filter instanceof LogicalTupleFilter) return evalLogical((LogicalTupleFilter) filter); if (filter instanceof CompareTupleFilter) return evalCompare((CompareTupleFilter) filter); return null; } BitMapFilterEvaluator(BitMapProvider bitMapProvider); ConciseSet evaluate(TupleFilter filter); static void main(String[] args);  }### Answer:
@Test public void testBasics() { for (int i = 0; i < basicFilters.size(); i++) { assertEquals(basicResults.get(i), eval.evaluate(basicFilters.get(i))); } }
@Test public void testLogicalAnd() { for (int i = 0; i < basicFilters.size(); i++) { for (int j = 0; j < basicFilters.size(); j++) { LogicalTupleFilter f = logical(FilterOperatorEnum.AND, basicFilters.get(i), basicFilters.get(j)); ConciseSet r = basicResults.get(i).clone(); r.retainAll(basicResults.get(j)); assertEquals(r, eval.evaluate(f)); } } }
@Test public void testLogicalOr() { for (int i = 0; i < basicFilters.size(); i++) { for (int j = 0; j < basicFilters.size(); j++) { LogicalTupleFilter f = logical(FilterOperatorEnum.OR, basicFilters.get(i), basicFilters.get(j)); ConciseSet r = basicResults.get(i).clone(); r.addAll(basicResults.get(j)); assertEquals(r, eval.evaluate(f)); } } }
@Test public void testNotEvaluable() { CompareTupleFilter notEvaluable = compare(colB, FilterOperatorEnum.EQ, 0); assertEquals(null, eval.evaluate(notEvaluable)); LogicalTupleFilter or = logical(FilterOperatorEnum.OR, basicFilters.get(1), notEvaluable); assertEquals(null, eval.evaluate(or)); LogicalTupleFilter and = logical(FilterOperatorEnum.AND, basicFilters.get(1), notEvaluable); assertEquals(basicResults.get(1), eval.evaluate(and)); }
