=head1 NAME

HTTP::MobileAgent::Plugin::Location::LocationObject - Object for handling location object


=head1 VERSION

This document describes HTTP::MobileAgent::Plugin::Location::LocationObject version 0.0.1


=head1 SYNOPSIS

  use HTTP::MobileAgent::Plugin::Location;

  my $ma = HTTP::MobileAgent->new;
  $ma->parse_location;
  my $loc = $ma->location;

  # If $loc is not undef, it is L object.
  # More detail information of above sequence, see L.

  # This class is subclass of L on default, or subclass of
  # L on optional.
  # So see L or L to know basic methods and properties.

  if ($loc->mode eq "gps") { ... }

  # Get location requested mode by B method.
  # It returns "gps" or "sector".

  if ($loc->accuracy eq "gps") { ... }

  # Get Accuracy of returned location by B method.
  # It returns "gps", "hybrid" or "sector".
  # Real accuracy value is different by carrears and generations, but almost like below:
  #   gps:      0m -  50m
  #   hybrid:  50m - 300m
  #   sector: 300m -

  my $mesh7 = $loc->mesh7;

  # Get 7th mesh code of i-Area specification.
  # See more detail on L.


=head1 NOTE

Value of B and B is sometimes not same.
Even if User want to get gps level accuracy data, but terminal cannot access gps satellite,
it fallback to hyblid or sector level accuracy.
