Like API
Explanation
The Like API records that a user likes an entity, counts the likes an entity received, and lists the users who liked it.
Call it from wiki pages through the Like Script Service, and from a Component through the Like Java API.
How the feature behaves is explained on three pages:
- Likes as Ratings — what the Ratings settings make of a like, and where likes are kept.
- Like Right — who is allowed to like.
- Like Caches — why a like count can go stale.
Like Storage Properties lists the two xwiki.properties keys that change where the average rating of a like is kept.
What readers actually click comes from the Like Application, which builds on this API and is documented for users and administrators.
