NAME

       Apache2::SiteControl::Rule - Permission manager access rule.

   DESCRIPTION
       Each rule is a custom-written class that implements some aspect of your site's access
       logic. Rules can choose to grant or deny a request.

          package sample::Test;

          use strict;
          use warnings;
          use Carp;
          use Apache2::SiteControl::Rule;

          use base qw(Apache2::SiteControl::Rule);

          sub grants($$$$)
          {
             my $this = shift;
             my $user = shift;
             my $action = shift;
             my $resource = shift;

             if($action eq "edit" && $resource->isa("sample::Record")) {
                return 1 if($user{name} eq "root");
             }

             return 0;
          }

          sub denies($$$$)
          {
             return 0;
          }

          1;

       The PermissionManager will only give permission if at least one rule grants permission,
       and no rule denies it.

       It is important that your rules never grant or deny a request they do not understand, so
       it is a good idea to use type checking to prevent strangeness.  Assertions should not be
       used if you expect different rules to accept different resource types or user types, since
       each rule is used on every access request.

EXPORT

       None by default.
