Array::Window 1.02

Many applications require that a large set of results be broken down into a smaller set of 'windows', or 'pages' in web language. Array::Window is a Perl module that implements an algorithm specifically for dealing with these windows. It is very flexible and permissive, making adjustments to the window as needed.<br /><br />Note that this is NOT under Math:: for a reason. It doesn't implement in a pure fashion, it handles idiosyncracies and corner cases specifically relating to the presentation of data.<br /><br />SYNOPSIS<br /><br /> # Your search routine returns an reference to an array<br /> # of sorted results of unknown quantity.<br /> my $results = SomeSearch->find( 'blah' );<br /> <br /> # We want to display 20 results at a time<br /> my $window = Array::Window->new(<br /> source => $results,<br /> window_start => 0,<br /> window_length => 20,<br /> );<br /> <br /> # Do we need to split into pages at all?<br /> my $show_pages = $window->required;<br /> <br /> # Extract the subset from the array<br /> my $subset = $window->extract( $results );<br /> <br /> # Are there 'first', 'last', 'next' or 'previous' windows?<br /> my $first = $window->first;<br /> my $last = $window->last;<br /> my $next = $window->next;<br /> my $previous = $window->previous;
