=head1 NAME

Froody::Response::String - create a response from a string

=head1 SYNOPSIS

  my $response = Froody::Response::String->new()
                                         ->structure($froody_method)
                                         ->set_string($string)
  print $response->render;

=head1 DESCRIPTION

This is a concrete implementation of Froody::Response.  It takes its input
from a valid Perl string, which you can set with C<set_string>:

  my $frs = Froody::Response::String->new();
  $frs->structure($froody_method);
  $frs->set_string( <<ENDOFRSP );
  <rsp stat="ok">
    <monger>L\x{e9}on Brocard</monger>
  </rsp>
  ENDOFRSP

Note that there's no XML declaration header there - one will be added
automatically.  You can also set the bytes directly:

  my $frs = Froody::Response::String->new();
  $frs->structure($froody_method);
  $frs->set_bytes( <<ENDOFRSP );
  <?xml version="1.0" encoding="utf-8" ?>
  <rsp stat="ok">
    <monger>L\x{c3}\x{a9}on Brocard</monger>
  </rsp>
  ENDOFRSP

In this case you are required to include the XML declaration header (as we
can't create one for you as we have no idea what encoding scheme the bytes are
using)

# set_string is documented
sub set_string {
  my $self = shift;
  $self->{bytes} = qq{<?xml version="1.0" encoding="utf-8" ?>\n};
  $self->{bytes} .= Encode::encode("utf-8", shift());
  return $self;
}

# set_bytes is documented
sub set_bytes {
  my $self = shift;
  $self->{bytes} = shift;
  return $self;
}

# just return the bytes
sub render { my $self = shift; $self->{bytes} }

=head2 Converting other Responses to Froody::Response::String objects

Once you've loaded this class you can automatically convert other
Froody::Response class instances to Froody::Response::String objects with
the C<as_string> method.

  use Froody::Response::PerlDS;
  use Froody::Response::String;
  my $string = Froody::Response::PerlDS
      ->new()
      ->structure($froody_method)
      ->content({ name => "foo", text => "bar" })
      ->as_string;
  print ref($string);  # prints "Froody::Response::String"

=cut

# rendering this class
# as_string is documented
sub as_string { return $_[0] }
sub Froody::Response::as_string
{
  my $self = shift;
  my $str = Froody::Response::String->new();
  $str->set_bytes($self->render);
  return $str;
}
