=head1 NAME
Data::HAL::URI - URI wrapper
=head1 VERSION
This document describes Data::HAL::URI version 1.001
=head1 SYNOPSIS
my $relation = $resource->relation->as_string;
=head1 DESCRIPTION
This is a wrapper for L<URI> objects.
=head1 INTERFACE
=head2 Composition
None, but L<URI> methods are delegated through the L</uri> attribute.
=head2 Constructors
=head3 C<new>
my $u = Data::HAL::URI->new('http://example.com/something');
Takes a string argument, returns a C<Data::HAL::URI> object.
=head2 Attributes
=head3 C<uri>
Type C<URI>, B<required>, B<readonly>, can only be set from the L</new> constructor.
This attribute delegates all methods to L<URI> except L</as_string>.
=head2 Methods
=head3 C<as_string>
Returns the original argument to the constructor if still equal to the L</uri>, where equality also takes CURIE
expansion into account, or otherwise the L</uri> as string.
The unaltered behaviour is still available through the L</uri> accessor, e.g.:
$resource->relation->uri->as_string
=head2 Exports
None.
=head1 DIAGNOSTICS
None.
=head1 CONFIGURATION AND ENVIRONMENT
Requires no configuration files or environment variables.
