WWW::REST - Base class for REST resources

This document describes version 0.01 of WWW::REST, released October 21, 2003.

use XML::RSS;
use WWW::REST;
$url = WWW::REST->new("http://nntp.x.perl.org/rss/perl.par.rdf");
$url->dispatch( sub {
my $self = shift;
die $self->status_line if $self->is_error;
my $rss = XML::RSS->new;
$rss->parse($self->content);
return $rss;
});
$url->get( last_n => 10 )->save("par.rdf");
$url->url("perl.perl5.porters.rdf")->get->save("p5p.rdf");
warn $url->dir->as_string; # "http://nntp.x.perl.org/rss/"
warn $url->parent->as_string; # "http://nntp.x.perl.org/"
$url->delete; # dies with "405 Method Not Allowed"

This module is a mixin of URI, LWP::UserAgent, HTTP::Response and an user-defined dispatch module. It is currently just a proof of concept for a resource-oriented API framework, also known as REST (Representational State Transfer).

Constructor (class method). Takes an URL string, returns a WWW::REST object. The optional arguments are passed to LWP::UserAgent->new.
Constructor (instance method). Takes an URL string, which may be relative to the object's URL. Returns a WWW::REST object, which inherits the same ua and dispatcher.
Gets or sets the dispatch code reference.
Gets or sets the embedded URI, LWP::UserAgent and HTTP::Response objects respectively. Note that $url can automatically delegate method calls to embedded objects, so normally you won't need to call those method explicitly.
Performs the corresponding operation to the object; returns the object itself. If dispatch is set to a code reference, the object is passed to it instead, and returns its return value.
Returns a WWW::REST object with the URL of the current object's parent directory.
Returns a WWW::REST object with the URL of the current object's current directory.

This module is considered highly experimental. The API may change without notice; suggestions are most welcome.
The documentation you are reading really needs a rewrite. :-)
