Jifty::DBI::Collection::Union - Deal with multiple Jifty::DBI::Collection result sets as one

       All rights reserved.

       This library is free software; you can redistribute it and/or modify it under the same terms as Perl
       itself.

       Implements a subset of the Jifty::DBI::Collection methods, but enough to do iteration over a bunch of
       results.  Useful for displaying the results of two unrelated searches (for the same kind of objects) in a
       single list.

new
       Create a new Jifty::DBI::Collection::Union object.  No arguments.

   addCOLLECTION
       Add Jifty::DBI::Collection object COLLECTION to the Union object.

       It must be the same type as the first object added.

   first
       Return the very first element of the Union (which is the first element of the first Collection).  Also
       reset the current pointer to that element.

   next
       Return the next element in the Union.

   last
       Returns the last item

   count
       Returns the total number of elements in the union collection

   goto_first_item
       Starts the recordset counter over from the first item. the next time you call "next", you'll get the
       first item returned by the database, as if you'd just started iterating through the result set.

   goto_item
       Unlike "goto_item" in Jifty::DBI::Collection, Union only supports going to the first item in the
       collection.

   is_last
       Returns true if the current row is the last record in the set.

   items_array_ref
       Return a reference to an array containing all objects found by this search.

       Will destroy any positional state.
