Subject RE: [jira] Closed: (LUCENENET-97) HitIterator does not correctly implement System.Collections.IEnumerator

I agree with DIGY as well.

If, as you say, the HitIterator is "not intended to provide a .NET IEnumerator behavior" than
the IEnumerator interface must be removed.
That it does not operate according to the IEnumerator documentation is a fatal flaw, and will
cause the application developer to experience unexpected and hard to diagnose failures.

This invalid implementation of IEnumerator is sufficient cause for my organization to prohibit
use of Lucene.Net in any development project.

George Aroush closed LUCENENET-97.
----------------------------------

    Resolution: Invalid

I agree with DIGY.

One of the goals of Lucene.Net is to keep it consistent with Lucene Java.  The behavior of
HitIterator is not intended to provide a .NET IEnumerator behavior, but, like DIGY said, an
efficient iteration over Lucene hits.  The current behavior of HitItterator is consistent
with the Lucene Java; this behavior must remain (and the efficiency).

Btw, another Apache project, NMaven (a port from Java to C#) has the following question: "There
is some concern that NMaven may be drifting from Maven in terms of common architecture/code".
 Lucene.Net should not drift.

I'm closing this issue.  Further discussion about it should move to the mailing list.

Regards,

> method MoveNext() is supposed to increment the position within the list; it does not.
> method Current() is supposed to return the object at the current position, but not change
the position within the list.
> It incorrectly moves to the next position.
