Jifty::DBI::CollectionUseriContributed Perl DoJifty::DBI::Collection::Union(3)

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

SYNOPSIS
	 use Jifty::DBI::Collection::Union;
	 my $U = new Jifty::DBI::Collection::Union;
	 $U->add( $tickets1 );
	 $U->add( $tickets2 );

	 $U->GotoFirstItem;
	 while (my $z =	$U->Next) {
	   printf "%5d %30.30s\n", $z->Id, $z->Subject;
	 }

WARNING
       This module is still experimental.

DESCRIPTION
       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.

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

   add COLLECTION
       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.
