[jira] [Commented] (OAK-4003) Add support for Group-Membership actions

["Alexander Klimetschek (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OAK-4003?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15143185#comment-15143185 ] 

Alexander Klimetschek commented on OAK-4003:
--------------------------------------------

Are the 2 variants (single vs. iterable) really needed? We could just have the Iterable variant and pass single members there as well.

> [~djaeggi], as discussed today it would be cool to provide an extension for the user/group actions that allowed to hook in additional processing/verification upon update of group membership.
> initial thoughts to be discussed and verified for feasibilty: 
> - create {{GroupAction}} interface extending {{AuthorizableAction}} (to not blow up the original interface with operations that only affect groups)
> - add 2 methods for addMember(s) and removeMember(s) each to cover both the add/removal by {{Authorizable}} and by multiple {{memberIds}}
> The actions should be called _after_ having successfully processed the modification and (in case on manipulation by ID) should only report those members that have been added/removed (see API contract of membership-update by ids).
> Methods could e.g. look something like
> {code}
>     void onMemberAdded(Group group, Authorizable member, Root root, NamePathMapper namePathMapper) throws RepositoryException;
>     
>     void onMembersAdded(Group group, Iterable<String> memberIds, Root root, NamePathMapper namePathMapper) throws RepositoryException;
>    void onMemberRemoved(Group group, Authorizable member, Root root, NamePathMapper namePathMapper) throws RepositoryException;
>     
>     void onMembersRemoved(Group group, Iterable<String> memberIds, Root root, NamePathMapper namePathMapper) throws RepositoryException;
> {code}
