NAME

       Data::Paginator - Pagination with Moose

VERSION

       version 0.08

SYNOPSIS

           use Data::Paginator;

           my $pager = Data::Paginator->new(
               current_page => 1,
               entries_per_page => 10,
               total_entries => 100,
           );

           print "First page: ".$pager->first_page."\n";
           print "Last page: ".$pager->last_page."\n";
           print "First entry on page: ".$pager->first."\n";
           print "Last entry on page: ".$pager->last."\n";

DESCRIPTION

       This is yet another pagination module.  It only exists because none of the other pager
       modules are written using Moose.  Sometimes there is a Moose feature X MooseX::Storage, in
       my case X that you need. It's a pain when you can't use it with an existing module.  This
       module aims to be completely compatible with the venerable Data::Page.  In fact, it's a
       pretty blatant copy of Data::Page, lifting code from some of it's methods.

SETS

       This module provides behavior compatible with Data::PageSet, allowing you to break your
       pagination into sets.  For example, if you have a large number of pages to show and would
       like to allow the user to 'jump' X pages at a time, you can set the "pages_per_set"
       attribute to X and populate the links in your pagination control with the values from
       "previous_set" and "next_set".

ATTRIBUTES

   current_page
       The current page.  Defaults to 1.  If you set this value to to a page number lesser than
       or greater than the range of the pager, then 1 or the last_page will be returned instead.
       It is safe to pass this numbers like -1000 or 1000 when there are only 3 pages.

   entries_per_page
       The number of entries per page, required at instantiation.

   last_page
       Returns the number of the last page.  Lazily computed, so do not set.

   next_set
       Returns the number of the next set or undefined if there is no next.

   pages_per_set
       If you have a large number of pages to show and would like to allow the user to 'jump' X
       pages at a time, you can set the "pages_per_set" attribute to X and populate the links in
       your pagination control with the values from "previous_set" and "next_set".

   previous_set
       Returns the set number of the previous set or undefined if there is no previous set.

   total_entries
       The total number of entries this pager is covering.  Required at instantiation.

   first
       Returns the number of the first entry on the current page.

   first_page
       Always returns 1.

METHODS

   entries_on_this_page
       Returns the number of entries on this page.

   first_set
       Returns 1 if this Paginator has pages_per_set.  Otherwise returns undef.

   last
       Returns the number of the last entry on the current page.

   next_page
       Returns the page number of the next page if one exists, otherwise returns false.

   page_for ($count)
       Returns the page number that the $count item appears on.  Returns undef if $count is
       outside the bounds of this Paginator.

   previous_page
       Returns the page number of the previous page if one exists, otherwise returns undef.

   set_for $page
       Returns the set number of the specified page.  Returns undef if the page exceeds the
       bounds of the Paginator.

   splice
       Takes in an arrayref and returns only the values which are on the current page.
