=head1 NAME

Pod::Simple::PullParserStartToken -- start-tokens from Pod::Simple::PullParser

=head1 SYNOPSIS

(See L&lt;Pod::Simple::PullParser&gt;)

=head1 DESCRIPTION

When you do $parser-&gt;get_token on a L&lt;Pod::Simple::PullParser&gt; object, you might
get an object of this class.

This is a subclass of L&lt;Pod::Simple::PullParserToken&gt; and inherits all its methods,
and adds these methods:

=over

=item $token-&gt;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-&gt;tagname(I&lt;somestring&gt;)

This changes the tagname for this start-token object.
You probably won't need
to do this.

=item $token-&gt;tag(...)

A shortcut for $token-&gt;tagname(...)

=item $token-&gt;is_tag(I&lt;somestring&gt;) or $token-&gt;is_tagname(I&lt;somestring&gt;)

These are shortcuts for C&lt;&lt; $token-&gt;tag() eq I&lt;somestring&gt; &gt;&gt;

=item $token-&gt;attr(I&lt;attrname&gt;)

This returns the value of the I&lt;attrname&gt; attribute for this start-token
object, or undef.

For example, parsing a LZ&lt;&gt;&lt;Foo/"Bar"&gt; 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-&gt;attr(I&lt;attrname&gt;, I&lt;newvalue&gt;)

This sets the I&lt;attrname&gt; attribute for this start-token object to
I&lt;newvalue&gt;.  You probably won't need to do this.

=item $token-&gt;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&lt;&lt; keys %{$token-&gt;attr_hash} &gt;&gt;

=back


You're unlikely to ever need to construct an object of this class for
yourself, but if you want to, call
C&lt;&lt;
Pod::Simple::PullParserStartToken-&gt;new( I&lt;tagname&gt;, I&lt;attrhash&gt; )
&gt;&gt;
