NAME
    HTTP::MobileAgent - HTTP mobile user agent string parser

SYNOPSIS
      use HTTP::MobileAgent;

      # from PSGI $env hash:
      my $agent = HTTP::MobileAgent->new( $env );

      # from %ENV (CGI mode):
      my $agent = HTTP::MobileAgent->new();

      # from Apache (mod_perl 1.x):
      my $agent = HTTP::MobileAgent->new(Apache->request);

      # from a HTTP::Headers / HTTP::Request object:
      my $agent = HTTP::MobileAgent->new( HTTP::Headers->new( ... ) );
      my $agent = HTTP::MobileAgent->new( HTTP::Request->new( ... ) );

      # from a raw user agent string:
      my $agent = HTTP::MobileAgent->new($agent_string);

      if ($agent->is_docomo) {
          # or if ($agent->name eq 'DoCoMo')
          # or if ($agent->isa('HTTP::MobileAgent::DoCoMo'))
          # it's NTT DoCoMo i-mode.
          # see what's available in H::MA::DoCoMo
      } elsif ($agent->is_vodafone) {
          # it's Vodafone(J-Phone).
          # see what's available in H::MA::Vodafone
      } elsif ($agent->is_ezweb) {
          # it's KDDI/EZWeb.
          # see what's available in H::MA::EZweb
      } else {
          # may be PC
          # $agent is H::MA::NonMobile
      }

      my $display = $agent->display;        # HTTP::MobileAgent::Display
      if ($display->color) { ... }

DESCRIPTION
    HTTP::MobileAgent parses HTTP_USER_AGENT strings of (mainly Japanese)
    mobile HTTP user agents. It'll be useful in page dispatching by user
    agents.

METHODS
    Here are common methods of HTTP::MobileAgent subclasses. More agent
    specific methods are described in each subclasses. Note that some of
    common methods are also overrided in some subclasses.

    new
          $agent = HTTP::MobileAgent->new;       # from %ENV
          $agent = HTTP::MobileAgent->new($env); # PSGI env hash
          $agent = HTTP::MobileAgent->new($r);   # Apache or HTTP::Request
          $agent = HTTP::MobileAgent->new($ua_string);

        Parses HTTP headers and constructs HTTP::MobileAgent subclass
        instance.

        If no argument is supplied, $ENV{HTTP_*} is used (i.e., expects a
        CGI environment to be setup)

        If a single hash reference is given, then that hash is treated as a
        PSGI environment hash.

        If a blessed reference which is based on Apache (mod_perl 1.x),
        HTTP::Headers or HTTP::Request is passed, those will be used
        accordingly to parse data.

        If a single scalar is given, then that is taken to be a raw user
        agent string. Note that most likely this form of usage will not give
        you much information, as some mobile agents put useful information
        on HTTP headers other than only "User-Agent:" (like
        "x-jphone-msname" in J-Phone).

    user_agent
          print "User-Agent: ", $agent->user_agent;

        returns User-Agent string.

    name
          print "name: ", $agent->name;

        returns User-Agent name like 'DoCoMo'.

    is_docomo, is_vodafone(is_j_phone, is_softbank), is_ezweb, is_wap1,
    is_wap2, is_tuka,is_non_mobile
           if ($agent->is_docomo) { }

        returns if the agent is DoCoMo, Vodafone(J-Phone) or EZweb.

    carrier
          print "carrier: ", $agent->carrier;

    carrier_longname
          print "carrier_longname: ", $agent->carrier_longname;

    display
          my $display = $agent->display;

        returns HTTP::MobileAgent::Display object. See
        HTTP::MobileAgent::Display for details.

    user_id
          my $user_id = $agent->user_id;

        return X-DCMGUID, X-UP-SUBNO or X-JPHONE-UID.

    gps_compliant
          if ($agent->gps_compliant) { }

        returns if the agent is GPS compliant.

NOTE
    "Why not adding this module as an extension of HTTP::BrowserDetect?"
        Yep, I tried to do. But the module's code seems hard enough for me
        to extend and don't want to bother the author for this
        mobile-specific features. So I made this module as a separated one.

MORE IMPLEMENTATIONS
    If you have any idea / request for this module to add new subclass, I'm
    open to the discussion or (more preferable) patches. Feel free to mail
    me.

OTHER LANGUAGE BINDINGS
    This module is now ported to PHP as Net::UserAgent::Mobile by Atsuhiro
    KUBO. See http://pear.php.net/package-info.php?pacid=180 for details.
