- =head1 NAME
-
- Pod::Simple::PullParserStartToken -- start-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> object, 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->tagname
-
- This returns the tagname for this start-token object.
- For example, parsing a "=head1 ..." line will give you
- a start-token with the tagname of "head1", token(s) for its
- content, and then an end-token with the tagname of "head1".
-
- =item $token->tagname(I<somestring>)
-
- This changes the tagname for this start-token object.
- You probably won't need
- to do this.
-
- =item $token->tag(...)
-
- A shortcut for $token->tagname(...)
-
- =item $token->is_tag(I<somestring>) or $token->is_tagname(I<somestring>)
-
- These are shortcuts for C<< $token->tag() eq I<somestring> >>
-
- =item $token->attr(I<attrname>)
-
- This returns the value of the I<attrname> attribute for this start-token
- object, or undef.
-
- For example, parsing a LZ<><Foo/"Bar"> link will produce a start-token
- with a "to" attribute with the value "Foo", a "type" attribute with the
- value "pod", and a "section" attribute with the value "Bar".
-
- =item $token->attr(I<attrname>, I<newvalue>)
-
- This sets the I<attrname> attribute for this start-token object to
- I<newvalue>. You probably won't need to do this.
-
- =item $token->attr_hash
-
- This returns the hashref that is the attribute set for this start-token.
- This is useful if (for example) you want to ask what all the attributes
- are -- you can just do C<< keys %{$token->attr_hash} >>
-
- =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::PullParserStartToken->new( I<tagname>, I<attrhash> )
- >>
