             Summary: WilcardPermission: any token
                 Key: SHIRO-438
                 URL: https://issues.apache.org/jira/browse/SHIRO-438
             Project: Shiro
          Issue Type: New Feature
          Components: Authorization (access control) 
    Affects Versions: 1.3.0
            Reporter: picpoc
            Priority: Minor
             Fix For: 1.3.0
         Attachments: wildcardpermission-any.patch

Attached is a proposal patch to add another special token in the 
WildcardPermission, the any token '?'.

When granting the any token on a permission level, it behaves exactly as the 
wildcard, and implies everything:
any -> any
any -> wildcard
any -> literals

When querying the any token on a permission level, it is implied by everything:
any -> any
wildcard -> any
literals -> any

Thus, it is quite similar to say: i don't care about the detail of this level, 
it's fine if the user is granted something on it. Typical use case is when 
using shiro permission to perform some fined-grained access control.

For instance to give read access on newsletter 13 to anyone who has been 
granted the access to read, edit or delete it. Instead of checking for:
    newsletter:view:13 or newsletter:edit:13 or newsletter:delete:13
we can simply check for:
    newsletter:?:13
