PPIx::Regexp::Token::Reference(User Contributed Perl DocumentatiPPIx::Regexp::Token::Reference(3)

NAME
       PPIx::Regexp::Token::Reference - Represent a reference to a capture

SYNOPSIS
	use PPIx::Regexp::Dumper;
	PPIx::Regexp::Dumper->new( 'qr{\1}smx' )
	    ->print();

INHERITANCE
       "PPIx::Regexp::Token::Reference" is a PPIx::Regexp::Token.

       "PPIx::Regexp::Token::Reference" is the parent of PPIx::Regexp::Token::Backreference,
       PPIx::Regexp::Token::Condition and PPIx::Regexp::Token::Recursion.

DESCRIPTION
       This abstract class represents a reference to a capture buffer, either numbered or named.
       It should never be instantiated, but it provides a number of methods to its subclasses.

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.

   absolute
	print "The absolute reference is ", $ref->absolute(), "\n";

       This method returns the absolute number of the capture buffer referred to. This is the
       same as number() for unsigned numeric references. If the reference is to a named buffer,
       "undef" is returned.

   is_named
	$ref->is_named and print "named reference\n";

       This method returns true if the reference is named rather than numbered.

   is_relative
	$ref->is_relative()
	    and print "relative numbered reference\n";

       This method returns true if the reference is numbered and it is a relative number (i.e. if
       it is signed).

   name
	print "The name is ", $ref->name(), "\n";

       This method returns the name of the capture buffer referred to. In the case of a reference
       to a numbered capture (i.e. "is_named" returns false), this method returns "undef".

   number
	print "The number is ", $ref->number(), "\n";

       This method returns the number of the capture buffer referred to. In the case of a
       reference to a named capture (i.e. "is_named" returns true), this method returns "undef".

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