=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> )
>>
