Defines an access control list (ACL) for wiki pages. An Access Control List is a data structure used to guard access to resources. An ACL can be thought of as a data structure with multiple ACL entries. Each ACL entry, of interface type AclEntry, contains a set of positive permissions associated with a particular principal. (A principal represents an entity such as an individual user or a group). The ACL Entries in each ACL observe the following rules:
This interface is a highly stripped-down derivation of the java.security.acl.Acl interface. In particular, the notion of an Acl "owner" has been eliminated, since JWPWiki pages do not have owners. An additional simplification compared to the standard Java package is that negative permissions have been eliminated. Instead, JSPWiki assumes a "default-deny" security stance: principals are granted no permissions by default, and posesses only those that have been explicitly granted to them. And finally, the getPermissions() and checkPermission() methods have been eliminated due to the complexities associated with resolving Role principal membership.
