Usage

From source file:org.jfree.data.time.DateRangeTest.java

/**
 * Confirm that a DateRange is immutable.
 */// w w w.  j a v  a  2 s  .  c  o m
@Test
public void testImmutable() {
    Date d1 = new Date(10L);
    Date d2 = new Date(20L);
    DateRange r = new DateRange(d1, d2);
    d1.setTime(11L);
    assertEquals(new Date(10L), r.getLowerDate());
    r.getUpperDate().setTime(22L);
    assertEquals(new Date(20L), r.getUpperDate());
