Examples of com.ecyrd.jspwiki.auth.acl.AclEntry

com.ecyrd.jspwiki.auth.acl.AclEntry

Represents one entry in an Access Control List (ACL).

An ACL can be thought of as a data structure with multiple ACL entry objects. Each ACL entry object contains a set of positive page permissions associated with a particular principal. (A principal represents an entity such as an individual user, group, or role). Each principal can have at most one ACL entry; that is, multiple ACL entries are not allowed for any principal.

This interface is functionally equivalent to the java.security.acl.AclEntry interface, minus negative permissions.
