Interface InternalUserPermissionDAO

public interface InternalUserPermissionDAO

Manages persistence of InternalGrantedPermission at the explicit / direct permission level. This class does not have a concept of implied permissions (eg. doesn't know that having SYS_ADMIN implies ADMIN) and deals only with direct permissions. Granting or revoking an explicit permission does not guarantee a change in actual user permissions due to potential implied permissions.

Method Detail

exists

boolean exists(InternalGrantedPermission permission)

Return true if the InternalGrantedPermission has been explicitly granted. Ie. there is a row matching the group and permission specified by the permission param

permission - the group/permission pair to search for

Returns:

true if the permission has been explicitly granted (not implicitly)

revoke

boolean revoke(InternalGrantedPermission permission)

Remove the explicit permission from the group.

Parameters:

permission - the group/permission pair to remove

Returns:

true if the permission existed and was removed

grant

void grant(InternalGrantedPermission permission)

Grant the explicit permission to the group. If the permission already explicitly exists, do nothing.

Parameters:

permission - the group/permission pair to create

getGroupMappingsWithGrantedPermission

Collection<GroupMapping> getGroupMappingsWithGrantedPermission(UserPermission permission)

Find all groups that have been explicitly (not implicitly) granted the provided permission

Parameters:

permission - permission to search for

Returns:

all groups with this permission

findHighestPermissionPerGroupByPrefix

List<PermittedGroup> findHighestPermissionPerGroupByPrefix(String prefix,
                                                           int start,

Find all groups with an explicit permission, and return their highest permission

Parameters:

prefix - prefix return only groups whose names start with this prefix

start - index to start page at

limit - max number of results to return, 0 for all results

Returns:

the highest permission for each group with an explicit permission ordered by groupName. If a group has ADMIN and SYS_ADMIN, only return SYS_ADMIN

findHighestPermissionPerGroup

List<PermittedGroup> findHighestPermissionPerGroup(int start,
                                                   int limit)

Find all groups with an explicit permission, and return their highest permission

Parameters:

start - index to start page at

limit - max number of results to return, 0 for all results

Returns:

the highest permission for each group with an explicit permission ordered by groupName. If a group has ADMIN and SYS_ADMIN, only return SYS_ADMIN

findAllPermissionsForGroup

List<InternalGrantedPermission> findAllPermissionsForGroup(String groupName,
                                                           long directoryId)

Find all permission entries for this group. Used for eg. cleaning up when deleting the group.
