NAME

Data::Paginated - paginate a list of data

SYNOPSIS

        my $paginator = Data::Paginated->new({
                entries => \@my_list,
                entries_per_page => $entries_per_page, 
                current_page => $current_page,
        });

        my @to_print = $paginator->page_data;

DESCRIPTION

Data::Paginated is a thin wrapper around Data::Pageset which adds the extra functionality of being able to get all the entries from a list that are on a given page.

METHODS

new

        my $paginator = Data::Paginated->new({
                entries => \@my_list,
                entries_per_page => $entries_per_page,
                current_page => $current_page,
        });

This can take all the arguments that can be passed to Data::Pageset, with the exception that instead of passing simply the total number of items in question, you actually pass the items as a reference.

page_data

        my @to_print = $paginator->page_data;

This returns a list of the entries that will be on the current page.

So, if you have a list of [ 1 .. 10 ], 3 entries per page, and current page is 2, this will return (4, 5, 6).
