=head1 NAME

Pod::Simple::PullParserTextToken -- text-tokens from Pod::Simple::PullParser

=head1 SYNOPSIS

(See L<Pod::Simple::PullParser>)

=head1 DESCRIPTION

When you do $parser->get_token on a L<Pod::Simple::PullParser>, you might
get an object of this class.

This is a subclass of L<Pod::Simple::PullParserToken> and inherits all its methods,
and adds these methods:

=over

=item $token->text

This returns the text that this token holds.  For example, parsing
CZ<><foo> will return a C start-token, a text-token, and a C end-token.  And
if you want to get the "foo" out of the text-token, call C<< $token->text >>

=item $token->text(I<somestring>)

This changes the string that this token holds.  You probably won't need
to do this.

=item $token->text_r()

This returns a scalar reference to the string that this token holds.
This can be useful if you don't want to memory-copy the potentially
large text value (well, as large as a paragraph or a verbatim block)
as calling $token->text would do.

Or, if you want to alter the value, you can even do things like this:

  for ( ${  $token->text_r  } ) {  # Aliases it with $_ !!
  
    s/ The / the /g; # just for example
    
    if( 'A' eq chr(65) ) {  # (if in an ASCII world)
      tr/\xA0/ /;
      tr/\xAD//d;
    }
    
    ...or however you want to alter the value...
  }

=back

You're unlikely to ever need to construct an object of this class for
yourself, but if you want to, call
C<<
Pod::Simple::PullParserTextToken->new( I<text> )
>>
