Subclasses will add methods, and will also inherit these methods: =over =item $token->type This returns the type of the token. This will be either the string "start", the string "text", or the string "end". Once you know what the type of an object is, you then know what subclass it belongs to, and therefore what methods it supports. Yes, you could probably do the same thing with code like $token->isa('Pod::Simple::PullParserEndToken'), but that's not so pretty as using just $token->type, or even the following shortcuts: =item $token->is_start This is a shortcut for C<< $token->type() eq "start" >> =item $token->is_text This is a shortcut for C<< $token->type() eq "text" >> =item $token->is_end This is a shortcut for C<< $token->type() eq "end" >> =item $token->dump This returns a handy stringified value of this object. This is useful for debugging, as in: while(my $token = $parser->get_token) { $DEBUG and print STDERR "Token: ", $token->dump, "\n"; ... } =back =head1 SEE ALSO My subclasses: L<Pod::Simple::PullParserStartToken>, L<Pod::Simple::PullParserTextToken>, and L<Pod::Simple::PullParserEndToken>.
