Brian Foster commented on OODT-68:
----------------------------------
- and actually . . . in order to get first page of a product type set and
number of products in that product type it currently causes 5 queries instead
of just one . . . getFirstPage(ProductType) requires two (one to get num of
hits and another to get products) . . . getLastProductPage(ProductType) calls
getFirstPage() and then gets products for last page . . . if a query takes
20-30 seconds (typical for large data sets) that is then 5x30 which is a LONG
time for a user to wait for a GUI to load
> Add Number of Product Hits to ProductPage

>
> - By adding get number of hits the method setTotalPages(int) is no longer
> needed; getTotalPages will calculate its return value based on page size and
> total hits
> - This also allows the number of products to be determined by just getting
> the first page, instead of getting last page which internally requires
> DataSourceCatalog to get first page and last page
