Path::Dispatcher::Rule::CodeRef(3pm)			User Contributed Perl Documentation		      Path::Dispatcher::Rule::CodeRef(3pm)

NAME
       Path::Dispatcher::Rule::CodeRef - predicate is any subroutine

SYNOPSIS
	   my $rule = Path::Dispatcher::Rule::CodeRef->new(
	       matcher => sub { time % 2 },
	       block => sub { warn "Odd time!" },
	   );

	   my $undef = $rule->match("foo"); # even time; no match :)

	   my $match = $rule->match("foo"); # odd time; creates a Path::Dispatcher::Match

	   $rule->run; # warns "Odd time!"

DESCRIPTION
       Rules of this class can match arbitrarily complex values. This should be used only when there is no other recourse, because there's no way
       we can inspect how things match.

       You're much better off creating a custom subclass of Path::Dispatcher::Rule if at all possible.

ATTRIBUTES
   matcher
       A coderef that returns "undef" if there's no match, otherwise a list of strings (the results).

       The coderef receives the path object as its argument, and the path string as $_.
