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> ) +>> + +=head1 SEE ALSO + +L<Pod::Simple::PullParserToken>, L<Pod::Simple>, L<Pod::Simple::Subclassing> + +=head1 COPYRIGHT AND DISCLAIMERS + +Copyright (c) 2002 Sean M.
