RE: [wtp-dev] FW: Arrays vs. Collections in new API
|
No, I
think we're primarily interested in "future proofing" the
api.
Yes,
we lose the strong typing offered by arrays in the short term, but we gain
binary compatibility when we are finally allowed to convert to
generics.
Except
for the most memory sensitive situations (and in fact I think
Konstantin actually found that he was using more memory implementing an array
based api), I believe that most people will be adopting generics in the
near future.
Once
you've tasted the generics koolaid, it's really painful to encounter
an array based api :-)

Thanks for "netting
this out", Konstantin.
Its a good
question, and a good time to ask, since normally, I think, Arrays are
preferred over Collections (for performance reasons),
but as mentioned in the longer append, returning
immutable collections is a good way to improve thread safety.
(I assume it the thread safety you're primarily
interested in?)
I doubt we could
find or agree on a "whole WTP approach" so if you know of any specific cases
or areas, you might
point those out in
feature requests with some assessment of impact, performance JUnits, etc.
Thanks for raising this.

No, we are not proposing to move to Java 5.0 for the 1.0
release. What the conversation was about and what we would like to propose to
WTP as a whole is to consider moving to using unparameterized Collections in
the API for the 1.0 release. Then, when platform and WTP moves to Java 5.0
(3.2/1.5?), the APIs can be changed to use parameterized collections without
breaking binary compatibility.
Thoughts?

Re: [wtp-dev] FW: Arrays vs. Collections in new API
This was interesting ... but to be clear, our 1.0 will be on
Eclipse 3.1.1 and, I'm guessing, when
Jim said "in the fall they will
start to use Java 5.0" I suspect he meant for the 3.2 stream.
Are you suggesting we standardize on Java 5.0 for our API and 1.0
release?
If so ... seems like a huge step, to me.
So ... just thought I'd ask for clarification ... maybe you were
just sharing
an interesting discussion?

to let me forward it to the list. Something to consider as we finalize
api for 1.0.
