DxHashMap can't clone when empty
Hi all,
The title says it all really. On a 1.1 VM DxHashMap.clone() ends up
calling new Hashtable(count()) where count() is the number of elements in
the map. However, when count() is 0 this is a bad thing. The following
version of clone() works:
public Object clone() {
int newSize = count();
if (newSize < 10)
newSize = 10;
DxMap newMap = new DxHashMap (newSize);
return clone (newMap);
}
later,
\x/ill :-}
P.S. If you are working with a 1.1 VM you'll want to get the sun 1.1
collections library from:
<http://java.sun.com/beans/infobus/index.html#DOWNLOAD_COLLECTIONS>
and then put the following import in some of the ODMG classes:
import com.sun.java.util.collections.*; // import java.util.*;
into:
ArrayOfObject.java
DArray.java
DCollection.java
DIterator.java
DList.java
DSet.java
you also need to remove some full qualification (e.g. turn java.util.List
into List) and rely on the import.
