public class UserCheckTag
extends WikiTagBase

Includes the content if an user check validates. This has been considerably enhanced for 2.2. The possibilities for the "status"-argument are:

• "anonymous" - the body of the tag is included if the user is completely unknown (no cookie, no password)
• "asserted" - the body of the tag is included if the user has either been named by a cookie, but not been authenticated.
• "authenticated" - the body of the tag is included if the user is validated either through the container, or by our own authentication.
• "assertionsAllowed" - the body of the tag is included if wiki allows identities to be asserted using cookies.
• "assertionsNotAllowed" - the body of the tag is included if wiki does not allow identities to be asserted using cookies.
• "containerAuth" - the body of the tag is included if the user is validated through the container.
• "customAuth" - the body of the tag is included if the user is validated through our own authentication.
• "known" - if the user is not anonymous
• "notAuthenticated" - the body of the tag is included if the user is not yet authenticated.

If the old "exists" -argument is used, it corresponds as follows:

exists="true" ==> status="known"
exists="false" ==> status="unknown"
It is NOT a good idea to use BOTH of the arguments.

Since:

2.0
