=head1 NAME

PPI::Token::Data - The actual data in the __DATA__ section of a file

=head1 INHERITANCE

  PPI::Token::Data
  isa PPI::Token
      isa PPI::Element

=head1 DESCRIPTION

The C<PPI::Token::Data> class is used to represent the actual data inside
a file's C<__DATA__> section.

One C<PPI::Token::Data> object is used to represent the entire of the data,
primarily so that it can provide a convenient handle directly to the data.

=head1 METHODS

C<PPI::Token::Data> provides one method in addition to those provided by
our parent L<PPI::Token> and L<PPI::Element> classes.

=cut

use strict;
use IO::String ();
use PPI::Token ();

use vars qw{$VERSION @ISA};
BEGIN {
	$VERSION = '1.220';
	@ISA     = 'PPI::Token';
}

# Methods

=pod

=head2 handle

The C<handle> method returns a L<IO::String> handle that allows you
to do all the normal handle-y things to the contents of the __DATA__
section of the file.

Unlike in perl itself, this means you can also do things like C<print>
new data onto the end of the __DATA__ section, or modify it with
any other process that can accept an L<IO::Handle> as input or output.

Returns an L<IO::String> object.

=cut

sub handle {
	my $self = shift;
	IO::String->new( \$self->{content} );
}

sub __TOKENIZER__on_line_start {
	my ( $self, $t ) = @_;

	# Add the line
	if ( defined $t->{token} ) {
		$t->{token}->{content} .= $t->{line};
	}
	else {
		defined( $t->{token} = $t->{class}->new( $t->{line} ) ) or return undef;
	}

	return 0;
}
