C<PPIx::Regexp::Token::Comment> is a

C<PPIx::Regexp::Token::Comment> has no descendants.


This class represents a comment - both parenthesized comments (i.e.
C<< (?# this is a comment ) >> and the /x mode end-of-line comments.

=head1 METHODS

This class provides no public methods beyond those provided by its


package PPIx::Regexp::Token::Comment;

sub explain {
    return 'Comment';

# This must be implemented by tokens which do not recognize themselves.
# The return is a list of list references. Each list reference must
# contain a regular expression that recognizes the token, and optionally
# a reference to a hash to pass to make_token as the class-specific
# arguments. The regular expression MUST be anchored to the beginning of
# the string.
sub __PPIX_TOKEN__recognize {
    return ( [ qr{ \A \( \? \# [^\)]* \) }smx ] );

# We anticipate that these tokens will be generated by other classes:
# PPIx::Regexp::Token::Structure for parenthesized comments, and
# PPIx::Regexp::Token::Literal for end-of-line /x mode comments.
