101 Note: This functionality is missing for pre_retrieve
102 It is possible for the pre_ methods (eg C<pre_write>) to
104 decline the action. This could be due to an authentication
105 check done by the plugin, due to the content, or whatever else
106 the plugin fancies. There are three possible return values from
107 a pre_ plugin:
108 C<-1> - Deny this action
110 C<0> or C<undef> - I have no opinion
111 C<1> - Allow this action
112 If you have only zeros, the action will be allowed. If you have ones
114 and zeros, it will also be allowed.
115 If you have minus ones and zeros, it will be denied. If you have minus
117 ones, ones and zeros, the sum will be used to decide.
118 For default deny, have one plugin return -1, and another only return 1
120 if the action is explicity allowed)
