Subject [GitHub] lucenenet pull request: Fix on the PQ.
Date Wed, 11 Feb 2015 19:13:28 GMT
Github user guidotag commented on the pull request:
    I realized that there are two different implementations of a PQ, one in Util and this
one in Support. Do we have two different ones for some reason? A couple of things I've noticed:
    - The Java version uses the Util's PQ. Moreover there seems to be no Support package,
which seems to contain emulations of Java features not present in C#. 
    - The Support's one is only used in the Search/TopTermsRewrite class. The Util's one is
much more referenced.
    - The only PQ's methods invoked from TopTermsRewrite are: PriorityQueue(int capacity),
PriorityQueue(), T Peek(), T Poll() (dequeueing without failure if the PQ is empty), bool
Offer(T item) (insertion) and int Count. All of these methods are provided by Util's PQ, with
the exception of Poll which could be added with little effort.
    All this facts make me think that we should replace the Support's duplicate by the Util's
preexisting PQ.
