Subject RE: [S2] Iterator Tag and Status Count
Date Thu, 27 Sep 2007 11:47:02 GMT
Thank you for clearing this up.  I had checked the JavaDoc before making
the post, as well, and as you report it is a bit thin.  Never occurred
to me that it was a 1 based index.  I have never seen that before.  I
guess someone thought it useful rather than just doing the math if
needed.

Thanks to all who responded!

Subject: Re: [S2] Iterator Tag and Status Count

I think count is a one based position in the iteration where as index is
zero based.  But there is almost no information in the documentation.
The tag library documentation simply says that a InteratorStatus is
pushed on the Value Stack.  And the JavaDocs for IteratorStatus has one
line of "useful" information:

"The iterator tag can export an IteratorStatus object so that one can
get information about the status of the iteration, such as the size,
current index, and whether any more items are available."

Which, since there is no size information in the IteratorStatus, could
be interpreted that the "count" represents the size.  It's too bad there
is no JavaDoc information on the methods, since that could easily clear
up the confusion.
