on commons fileupload list there was the need to have streaming for Parts.
As of today Servlet API enables to only get a list and not an iterator -
even if it uses it under the hood.
:/
It's a Collection, though, and not a List, so there is a little more
flexibility.
Any way tomcat pushes that need (Iterator or Stream I guess) to the servlet
EG for next version?
We could certainly propose it. Something like
Iterator HttpServletRequest.getPartIterator()
and/or
Stream HttpServletRequst.getPartStream()
Do we want to provide this thru the current API implementing a LazyList
(while only Iterator is touched the list is not materialized)?
If implemented as a LazyList, then getParts().iterator() will get you
what you want and the Servlet API need not be modified. On the other
hand, supporting such streaming interfaces better-communicates the
application's intent to consume the parts in a streaming fashion rather
than all-at-once.
But it may delay IO errors until after getParts() is called. How would
we handle that? With some kind of RuntimeException thrown from
Collection, Iterator, and Stream operations?
