Pod::Simple::PullParserToken \-\- tokens from Pod::Simple::PullParser
.SH SYNOPSIS
.IX Header "SYNOPSIS"
Given a \f(CW$parser\fR that's an object of class Pod::Simple::PullParser
(or a subclass)...
.PP
.Vb 4
\& while(my $token = $parser\->get_token) {
\& $DEBUG and print STDERR "Token: ", $token\->dump, "\en";
\& if($token\->is_start) {
\& ...access $token\->tagname, $token\->attr, etc...
\&
\& } elsif($token\->is_text) {
\& ...access $token\->text, $token\->text_r, etc...
\&
\& } elsif($token\->is_end) {
\& ...access $token\->tagname...
\&

\& }

(Also see Pod::Simple::PullParser)
.SH DESCRIPTION
.IX Header "DESCRIPTION"
When you do \f(CW$parser\fR\->get_token on a Pod::Simple::PullParser, you should
get an object of a subclass of Pod::Simple::PullParserToken.
.PP
Subclasses will add methods, and will also inherit these methods:
.ie n .IP $token\->type 4
.el .IP \f(CW$token\fR\->type 4
.IX Item "$token->type"
This returns the type of the token. This will be either the string
"start", the string "text", or the string "end".
.Sp
Once you know what the type of an object is, you then know what
subclass it belongs to, and therefore what methods it supports.
.Sp
Yes, you could probably do the same thing with code like
\&\f(CW$token\fR\->isa('Pod::Simple::PullParserEndToken'), but that's not so
pretty as using just \f(CW$token\fR\->type, or even the following shortcuts:
.ie n .IP $token\->is_start 4
.el .IP \f(CW$token\fR\->is_start 4
.IX Item "$token->is_start"
This is a shortcut for \f(CW\*(C`$token\->type() eq "start"\*(C'\fR
.ie n .IP $token\->is_text 4
.el .IP \f(CW$token\fR\->is_text 4
.IX Item "$token->is_text"
This is a shortcut for \f(CW\*(C`$token\->type() eq "text"\*(C'\fR
.ie n .IP $token\->is_end 4
.el .IP \f(CW$token\fR\->is_end 4
.IX Item "$token->is_end"
This is a shortcut for \f(CW\*(C`$token\->type() eq "end"\*(C'\fR
.ie n .IP $token\->dump 4
.el .IP \f(CW$token\fR\->dump 4
.IX Item "$token->dump"
This returns a handy stringified value of this object. This
is useful for debugging, as in:
.Sp
.Vb 4
\& while(my $token = $parser\->get_token) {
\& $DEBUG and print STDERR "Token: ", $token\->dump, "\en";
\& ...
\& }
