Data::Page::Tied - Tied interface for the Data::Page module
use Data::Page::Tied; $handler = tie @data, 'Data::Page::Tied', [qw(some data to start with)], $entries_per_page, $current_page; push @data, @more_data; print "first entry on page ", $handler->current_page(), " is ", $handler->first();
This module depends on
Data::Page::Tied module adds a tied interface to the object-oriented interface defined by Leon Brocard's
Data::Page module. It also adds several methods to set and get the current page and the number of data items per page.
Please read Data::Page as
Data::Page::Tied inherits all methods from
The tying constructor has the following syntax:
tie @ary, 'Data::Page::Tied', ARRAYREF, INTEGER, INTEGER;
Where the referenced array may contain any data to start with and the integers denote the number of entries per page and the current page respectively.
This is the constructor. It is invoked by the tied interface, but using it directly allows for two distinct ways of creating new objects:
You may use the same syntax as the tied interface or you may use the following syntax to get an ordinary
Data::Pageobject instead of a
Data::Page::Tied->new( INTEGER, @args );
Where the integer is the number of elements.
This method returns the number of items in the tied array.
This method sets the current page. You may find the current page by using the inherited
This method sets the number of items displayed per page. You may find the current number of items displayed per page by using the inherited
This accessor is used to get or set any specific entry. It takes one or two arguments. The first argument is always the array index and the second (optional) argument is the value you want to set
Additional method to make the interface more consistent. Takes two arguments. See entry.
