Pod::Simple::PullParserToken

NAME

Pod::Simple::PullParserToken -- tokens from Pod::Simple::PullParser

SYNOPSIS

Given a $parser that's an object of class Pod::Simple::PullParser (or a subclass)...

  1.   while(my $token = $parser->get_token) {
  2.     $DEBUG and print "Token: ", $token->dump, "\n";
  3.     if($token->is_start) {
  4.       ...access $token->tagname, $token->attr, etc...
  6.     } elsif($token->is_text) {
  7.       ...access $token->text, $token->text_r, etc...
  8.     
  9.     } elsif($token->is_end) {
  10.       ...access $token->tagname...
  11.     
  12.     }
  13.   }

(Also see Pod::Simple::PullParser)

DESCRIPTION

When you do $parser->get_token on a Pod::Simple::PullParser, you should get an object of a subclass of Pod::Simple::PullParserToken.

Subclasses will add methods, and will also inherit these methods:

  • $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:

  • $token->is_start

    This is a shortcut for $token->type() eq "start"

  • $token->is_text

    This is a shortcut for $token->type() eq "text"

  • $token->is_end

    This is a shortcut for $token->type() eq "end"

  • $token->dump

    This returns a handy stringified value of this object. This is useful for debugging, as in:

    1.   while(my $token = $parser->get_token) {
    2.     $DEBUG and print "Token: ", $token->dump, "\n";
    3.     ...
    4.   }
