NAME
Data::Paginator - Pagination with Moose
VERSION
version 0.07
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 – MooseX::Storage, in my case – 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.
