From source file:com.isentropy.accumulo.test.AccumuloMapTest.java

public void testMultiMap(Connector c, int maxValues)
        throws AccumuloException, AccumuloSecurityException, TableNotFoundException {
    AccumuloSortedMap<Number, Number> mm = new AccumuloSortedMap(c, Util.randomHexString(10));
    mm.setMaxValuesPerKey(maxValues);// w w  w . ja v  a2s.co  m
    assertTrue(mm.getMaxValuesPerKey() == maxValues);
    System.out.println("mm.getMultiMapMaxValues() == " + mm.getMaxValuesPerKey());
    mm.put(1, 2);
    mm.put(1, 3);
    mm.put(1, 4);
    mm.put(2, 22);
    StatisticalSummary row1 = mm.rowStats().get(1);
    assertTrue(row1.getMean() == 3.0);
    assertTrue(row1.getMax() == 4.0);
    // size should reflect # keys
    assertTrue(mm.size() == 2);
    // count multiple values
    assertTrue(mm.sizeAsLong(true) == 4);
    //4 +22
    assertTrue(mm.valueStats().getSum() == 26);
    //2+3+4+22
    StatisticalSummary stats = mm.valueStats(true);
    double sum = stats.getSum();
    assertTrue(mm.valueStats(true).getSum() == 31);
