Konrad Windszus updated SLING-4377: ----------------------------------- Fix Version/s: API 2.9.0 > Add JSR305 nullness annotations to Sling API > -------------------------------------------- > > Key: SLING-4377 > URL: https://issues.apache.org/jira/browse/SLING-4377 > Project: Sling > Issue Type: Improvement > Components: API > Reporter: Konrad Windszus > Assignee: Konrad Windszus > Fix For: API 2.9.0 > > > Since consumers of the Sling API always have to keep in mind whether a > null-check is necessary it would be good to add JSR 305 annotations to the > API. > See also http://www.mail-archive.com/dev@sling.apache.org/msg42199.html. > At least Eclipse as well as Findbugs are supporting those and Oak Solr is > using those already (https://issues.apache.org/jira/browse/OAK-2303). > Only the following 2 annotations should be used: > # {{@Nonnull}}, for return values which are not supposed to be {{null}} or > parameters which must not be {{null}}. > # {{@CheckForNull}}, for return values wich may be null {{null}}. > Those are the only ones being supported by both Eclipse and Findbugs (compare > with http://sourceforge.net/p/findbugs/bugs/1355/) > {{@Nullable}} is basically ignored by Findbugs > (http://findbugs.sourceforge.net/manual/annotations.html) and should > therefore not be used. The package annotation for the default handling should > also not be used (because either {{@Nullable}} or {{@CheckForNull}} is > ignored by Eclipse then. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
