NAME

       Data::HAL::Link - Hypertext Application Language link

VERSION

       This document describes Data::HAL::Link version 1.001

SYNOPSIS

           map { +{
               href => $_->href->uri->as_string,
               rel  => $_->relation->uri->as_string
           } } @{ $resource->links }

DESCRIPTION

       This section is completely quoted from the specification:

       A Link Object represents a hyperlink from the containing resource to a URI.

INTERFACE

   Composition
       None.

   Constructors
       "new"

       When the "deprecation" attribute is set, the constructor logs a Log::Any warning:

       "The link (relation: "%s", href: "%s") is deprecated, see <%s>"

       You can consume it with a Log::Any::Adapter of your choice, e.g.

           use Log::Any::Adapter 'Stderr';

       Otherwise the constructor behaves like the default Moo constructor. Returns a
       "Data::HAL::Link" object.

   Attributes
       Perl strings are coerced to the Data::HAL::URI type in the attributes "relation", "href",
       "deprecation", "profile".

       "relation"

       Type Data::HAL::URI, required, link relation <http://tools.ietf.org/html/draft-kelly-json-
       hal#section-8.2>

       "href"

       Type Data::HAL::URI, required, link target URI or URI template
       <http://tools.ietf.org/html/draft-kelly-json-hal#section-5.1>

       "templated"

       Type boolean, whether "href" is a URI template <http://tools.ietf.org/html/draft-kelly-
       json-hal#section-5.2>

       Perl boolean values are coerced to the boolean type.

       "type"

       Type MIME::Type, media type of the "href" resource <http://tools.ietf.org/html/draft-
       kelly-json-hal#section-5.3>

       "deprecation"

       Type Data::HAL::URI, if existing indicates the link is deprecated
       <http://tools.ietf.org/html/draft-kelly-json-hal#section-5.4>

       Setting the attribute triggers a log message in the constructor "new".

       "name"

       Type "Str", secondary key for selecting link objects which share the same relation type
       <http://tools.ietf.org/html/draft-kelly-json-hal#section-5.5>

       "profile"

       Type Data::HAL::URI, RFC 6906 profile of the target resource
       <http://tools.ietf.org/html/draft-kelly-json-hal#section-5.6>

       "title"

       Type "Str", labels the link with a human-readable identifier
       <http://tools.ietf.org/html/draft-kelly-json-hal#section-5.7>

       "hreflang"

       Type "Str", indicates the language of the target resource
       <http://tools.ietf.org/html/draft-kelly-json-hal#section-5.8>

   Methods
       "as_http_link_value"

       Returns the link as a RFC 5988 "link-value" <http://tools.ietf.org/html/rfc5988#section-5>
       string, e.g.  "</orders?page=2>;rel="next"".
