=head1 NAME
|
|
|
|
Data::HAL::URI - URI wrapper
|
|
|
|
=head1 VERSION
|
|
|
|
This document describes Data::HAL::URI version 1.000
|
|
|
|
=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.
