Interface AccessAdapter

All Known Implementing Classes:

BaseAccessAdapter, GrouperAccessAdapter, GrouperNonDbAccessAdapter

public interface AccessAdapter

Grouper Access Privilege interface.

Unless you are implementing a new implementation of this interface, you should not need to directly use these methods as they are all wrapped by methods in the Group class.

If you are implementing your own access adapter, you should probably extend BaseAccessAdapter

for a group query, check to make sure the subject can see the records (if filtering HQL, you can do the postHqlFilterGroups instead if you like). Note, this joins to tables, so the queries should probably be "distinct"

Parameters:

grouperSession -

subject - which needs view access to the groups

hql - is the select and part part (hql prefix)

hqlQuery -

groupColumn - is the name of the group column to join to

privInSet - find a privilege which is in this set (e.g. for view, send all access privs). There are pre-canned sets in AccessPrivilege

                                            boolean considerAllSubject)

for a group query, check to make sure the subject cant see the records (if filtering HQL, you can do the postHqlFilterGroups instead if you like).

Parameters:

grouperSession -

subject - which needs view access to the groups

hql - is the select and part part (hql prefix)

hqlQuery -
