Subject [jira] Commented: (HARMONY-4203) [classlib][luni][java6] New feature of java.util.PriorityQueue for java6
Date Tue, 19 Jun 2007 05:32:26 GMT

Robert Hu commented on HARMONY-4203:

Tim. I think at least half of this patch is Java 6 specific.
#1 (change of "remove" method) is a different behavior in Java 6, you can also apply this
patch into Java 5 trunk and you can see the updated PriorityQueueTest can passes on RI 6 but
fails on RI 5. So, it is Java 6 specific.
#2 may be also a feature of Java 5. But according to the spec, there's no doc of methods "contains(Object
object),toArray(),toArray(T[] array)" of PriorityQueue in Java 5. In Java 5, these 3 methods
are maked as "Methods inherited from sub class XXX". We can see that they're "pulled down"
to the class PriorityQueue in Java 6.

So, I think we have two choices now, one is to apply this patch only into Java 6 branch, the
other is to split it into 2 patches, one for Java 5 including the 3 inherited methods and
one for Java 6 including only the update of "remove" mehtod and related test cases.

Tim, any idea? Thanks a lot!

> I've added the new feature of java.util.PriorityQueue for java6:
> 1. the behavior of remove method is changed, and some relative test cases is added
> 2. some methods in "java.util.AbstractCollection" of java5 are moved into java.util.PriorityQueue
(push down) of java6, also with some relative test cases:
>           public boolean contains(Object object)
>           public Object[] toArray()
>           public <T> T[] toArray(T[] array)
