PPIx::Regexp::Token::CharClass::POSIX::Unknown - Represent an unknown or unsupported POSIX character class

SYNOPSIS

Top

 use PPIx::Regexp::Dumper;
 PPIx::Regexp::Dumper->new( 'qr{ [[=a=]] }smx' )
     -print()

INHERITANCE

Top

PPIx::Regexp::Token::CharClass::POSIX::Unknown is a PPIx::Regexp::Token::CharClass::POSIX.

DESCRIPTION

Top

This class represents POSIX character classes which are recognized but not supported by Perl. At the moment this means [=a=] (equivalence classes), and [.ch.] (collating symbols).

Caveat: If any of these becomes supported by Perl in the future, they will become represented as PPIx::Regexp::Token::CharClass::POSIX objects, with an appropriate perl_version_introduced() value.

METHODS

Top

This class provides no public methods beyond those provided by its superclass.

SUPPORT

Support is by the author. Please file bug reports at http://rt.cpan.org, or in electronic mail to the author.
