How to get all User Groups of a Site programmatically using Java API?

[mbel]

Hello,

Is there any way of getting the list of all UserGroups and SubUserGroups of a Site?

Currently I see only method listMembers() which returns only the list of Users, not the groups.

Thank you in advance.

You can try listMembers method and set argument collapseGroups=true.

This again returns all users, but not the group of users.

I want to get for example ->  <GROUP_test, role> (which contain users: user1, user2) and after that get the List of that group which should return - user1, user2;

Instead I get -> <user1, role>, <user2, role> from the map which return that method.

Ok, so for my case it should be =false and it works

When you want to get all the users and/or groups within sites you may also always use the AuthorityService API to list them. The SiteService API only provides the convenience operations that are needed e.g. to provide site management functionality in the UI. SiteService.getSiteGroup(shortName) gets you the Alfresco group that contains all the roles of the site, and transitively all the groups / users. You can use that in conjunction with AuthorityService.getContainedAuthorities(authorityType, name, immediate) to retrieve members.

Is there any way not specifying the authorityType? Otherwise I have to foreach them role by role, right?

[afaust]

You can simply provide authorityType as null and both groups AND users will be returned. The authorityType has nothing to do with the site role - these can be differentiated via SiteService.getSiteRoleGroup(shortName, roleName)

[mbel]

For the method - authorityService.getContainedAuthorities(authorityType, name, immediate);

Could you please tell me what exactly the paramether name (the name of the containing authority) means.

The GroupName of a Site or ? As I receive nullpointer exception...

[afaust]

Obviously it refers to the name of the authority of which to get the contained authorities. In this case it needs the full authority name as returned by the SiteService.getSiteRoleGroup(shortName, role) or SiteService.getSiteGroup(shortName)

Yes, I tried with both, but currently trying to investigate from where it returns null pointer exception.
