PPIx::Regexp::Token::Code(3pm)				User Contributed Perl Documentation			    PPIx::Regexp::Token::Code(3pm)

NAME
PPIx::Regexp::Token::Code - Represent a chunk of Perl embedded in a regular expression. SYNOPSIS
use PPIx::Regexp::Dumper; PPIx::Regexp::Dumper->new( 'qr{(?{print "hello sailor "})}smx')->print; INHERITANCE
"PPIx::Regexp::Token::Code" is a PPIx::Regexp::Token. "PPIx::Regexp::Token::Code" is the parent of PPIx::Regexp::Token::Interpolation. DESCRIPTION
This class represents a chunk of Perl code embedded in a regular expression. Specifically, it results from parsing things like (?{ code }) (??{ code }) or from the replacement side of an s///e. Technically, interpolations are also code, but they parse differently and therefore end up in a different token. METHODS
This class provides the following public methods. Methods not documented here are private, and unsupported in the sense that the author reserves the right to change or remove them without notice. ppi This convenience method returns the PPI::Document representing the content. This document should be considered read only. SUPPORT
Support is by the author. Please file bug reports at <http://rt.cpan.org>, or in electronic mail to the author. AUTHOR
