Method Detail

isUserDirectMember

boolean isUserDirectMember(long directoryId,
                           String userName,
                           String groupName)

Determines whether the user is a direct member of the group.

Parameters:

directoryId - the directory to perform the operation

userName - user

groupName - group

Returns:

true if the user is a direct member of the group

isGroupDirectMember

boolean isGroupDirectMember(long directoryId,
                            String childGroup,
                            String parentGroup)

Determines whether the group is a direct member of the (supposedly) parent group.

Parameters:

directoryId - the directory to perform the operation

childGroup - child group

parentGroup - parent group

Returns:

true if the group is a direct member of the (supposedly) parent group

addUserToGroup

void addUserToGroup(long directoryId,
                    String userName,
                    String groupName)
             throws UserNotFoundException,
                    GroupNotFoundException,
                    MembershipAlreadyExistsException

Adds user as a member of group.

Parameters:

directoryId - the directory to perform the operation

userName - user

groupName - group

Throws:

UserNotFoundException - if the user does not exist

GroupNotFoundException - if the group does not exist

MembershipAlreadyExistsException - if the user is already a direct member of the group

addAllUsersToGroup

BatchResult<String> addAllUsersToGroup(long directoryId,
                                       Collection<String> userNames,
                                       String groupName)
                                throws GroupNotFoundException

Bulk adds all the given users into the given group. Users that are already direct members of the group are reported as failures. Usernames that cannot be found in the database are also reported as failures. Implementations must make sure that changes in bulk methods such as this are immediately visible to other bulk methods. For example, if this is run in a transaction, either that transaction must be committed when this method returns, or all other bulk method implementations must guarantee to reuse the same transaction.

Parameters:

directoryId - the directory to perform the operation

userNames - the collection of users

groupName - name of the group

Returns:

result containing both successful (membership successfully added) and failed users (unknown username, or already existing membership)

Throws:

GroupNotFoundException - if the group does not exist

addGroupToGroup

void addGroupToGroup(long directoryId,
                     String childGroup,
                     String parentGroup)
              throws GroupNotFoundException,
                     MembershipAlreadyExistsException

Adds group as a child of the (supposedly) parent group.

Parameters:

directoryId - the directory to perform the operation

childGroup - the (supposedly) child group

parentGroup - parent group

Throws:

GroupNotFoundException - if either child or parent group is not found

MembershipAlreadyExistsException - if the child group is already a child of the parent group

removeUserFromGroup

void removeUserFromGroup(long directoryId,
                         String userName,
                         String groupName)
                  throws UserNotFoundException,
                         GroupNotFoundException,
                         MembershipNotFoundException

Removes user as a member of the given group.

Parameters:

directoryId - the directory to perform the operation

userName - user

groupName - group

Throws:

UserNotFoundException - if the user does not exist

GroupNotFoundException - if the group does not exist

MembershipNotFoundException - if the user is not a member of the said group

removeGroupFromGroup

void removeGroupFromGroup(long directoryId,
                          String childGroup,
                          String parentGroup)
                   throws GroupNotFoundException,
                          MembershipNotFoundException

Removes group from the parent group.

Parameters:

directoryId - the directory to perform the operation

childGroup - child group

parentGroup - parent group

Throws:

GroupNotFoundException - if either child or parent group does not exist

MembershipNotFoundException - if the membership relationship between the child and parent group does not exist

search

<T> List<T> search(long directoryId,
                   MembershipQuery<T> query)

Search for memberships by the given criteria.

Parameters:

directoryId - the directory to perform the operation

query - criteria

Returns:

list (can be empty but never null) of memberships which match the given criteria

countDirectMembersOfGroup

BoundedCount countDirectMembersOfGroup(long directoryId,
                                       String groupName,
                                       int potentialMaxCount)

Count the direct members of a group with a recommended upper bound on the count.

The upper bound is there so that, in directories that do not support efficient counting of memberships, less work may be performed.

Important: Please note that any directory wishing to implement this method should make it as efficient as possible. Such that an administrator could land on a page that showed ~20 groups, run this method once per group, and it would still return results as efficiently as possible.

Parameters:

directoryId - the directory to perform the operation

groupName - the name of the group to search for

potentialMaxCount - a suggested minimum number of elements for the implementation to count. The implementation will only use this number if it can get efficiency benefits; otherwise this number may be ignored.

Returns:

A bounded count of the number of memberships in the given group for the provided directory. If the group does not exist then BoundedCount.exactly(long) 0 will be returned.
