Class UserPrefetcher

java.lang.Object

com.atlassian.confluence.impl.content.render.prefetch.UserPrefetcher

All Implemented Interfaces:

ResourcePrefetcher<UserResourceIdentifier>

public class UserPrefetcher
extends Object
implements ResourcePrefetcher<UserResourceIdentifier>

An implementation of ResourcePrefetcher for UserResourceIdentifiers. This will attempt to pre-fetch any ConfluenceUser objects by their UserKey.

Note that any UserResourceIdentifiers with a null UserKey will not be pre-fetched. Such a condition is possible (e.g. with unmigrated, pre-userkey data), but not expected to happen in normal usage.

Since:

5.10
