=head1 DESCRIPTION
|
|
|
|
This module provides functions for manipulating virtual virtualshelves,
|
|
including creating and deleting virtualshelves, and adding and removing
|
|
items to and from virtualshelves.

|
|
|
|
Returns the number of shelves specified by C<$row_count> and C<$offset> as well as the total
|
|
number of shelves that meet the C<$owner> and C<$mincategory> criteria. C<$mincategory>,
|
|
C<$row_count>, and C<$offset> are required. C<$owner> must be supplied when C<$mincategory> == 1.
|
|
When C<$mincategory> is 2 or 3, supply undef as argument for C<$owner>.
|
|
C<$shelflist>is a reference-to-hash. The keys are the virtualshelves numbers (C<$shelfnumber>, above),
|
|
and the values (C<$shelfhash>, above) are themselves references-to-hash, with the following keys:
|
|
|
|

A string. The name of the shelf.
|
|
|
|
=item C<$shelfhash-E<gt>{count}>
|
|
|
|
The number of virtuals on that virtualshelves.
