<DIV><FONT face=Arial size=2>I agree that
it is time to add type safety (generics)
to the jdbm 1.1 code base. It's past
time to move past the old JDKs... Anyone
still using the old JDK can easily use the
jdbm 1.0 release. </FONT></DIV>

<DIV><FONT face=Arial size=2>I would also
like to see Iterable implementations for
the BTree, but even getting a reliable Interator
on the current BTree is not possible without
a pretty significant rewrite (the problem
is that the current Tuple Browser system
does not properly adapt to structural changes
to the tree). I do currently have an
Iterator implementation that is safe to use,
but it's performance is not great b/c it
has to re-query the state of the tree for
each iteration instead of using the next/previous
pointers in the leafe nodes.</FONT></DIV>

breaking compatibility with<BR>older JDK's.
Is that a problem to someone? It's not a

the code to be compliant with the current
