Summary: Missing putAll(Map map) in MultiHashMap since 3.1
Product: Commons
Version: 3.1
Platform: PC
OS/Version: Windows 2000
Status: NEW
Severity: normal
Priority: P2
Component: Collections
AssignedTo: commons-dev@jakarta.apache.org
ReportedBy: sven.macke@rewe.de
I just upgraded to version 3.1 and noticed some errors in my application. The
cause is the method putAll(Map map) I used to call on a MultiHashMap to copy to
content of one to another. That method is not defined in MultiHashMap any more,
so HashMap.putAll(Map map) is used. The result of that is a MultiHashMap that
contains ONE value per key and the value itself is a Collection.
Here is some test code I would expect to work, but it fails:
public class MultiHashMapTest extends TestCase
{
public void testIt()
{
MultiMap original = new MultiHashMap();
original.put("key", "object1");
original.put("key", "object2");
MultiMap copy = new MultiHashMap();
copy.putAll(original);
assertEquals(original.values().size(), copy.values().size());
assertTrue(copy.containsValue("object1"));
assertTrue(copy.containsValue("object2"));
}
}
