Templates problem

Hi,

if there is:

Expand|Select|Wrap|Line Numbers

 public class Range<T extends Comparable<T>> extends Scope<T> implements Cloneable
 

, can I define this one:

Expand|Select|Wrap|Line Numbers

 public class RangeList<T extends Comparable<T>, R extends Range<T>> extends ArrayList<R>
 

without giving "T extends Comparable<T>"?

It would be perfect to say:

Expand|Select|Wrap|Line Numbers

RangeList<R extends Range<T extends Comparable<T>>>

:).

Thanks in advance,
Etam.

Maybe it is not related but RangeList<Date, Timerange> duties, has:

Expand|Select|Wrap|Line Numbers

public final void crop(List<Range<T>> ranges)

method, and I can't pass List<Timerange> there (Timerange extends Range<Date> :/.

I have to do this:

Expand|Select|Wrap|Line Numbers

 
List<Timerange> list = dateType.filter(starts, ends);

List<Range<Date>> l = new ArrayList<Range<Date>>();

Collections.copy(l, list);

duties.crop(l);
