Interface UserManager

@ProviderType
public interface UserManager

The UserManager provides access to and means to maintain authorizable objects i.e. users and groups. The UserManager is bound to a particular Session.

Note that all create calls will modify the session associated with the UserManager (whether this is the current session or not depends on the repository configuration). If the user manager is not in "autosave" mode (see isAutoSave()), problems like overlapping creation of intermediate nodes may only surface upon a subsequent Session.save() operation; callers should be prepared to repeat them in case this happens.

Create a new system user for the specified userID. The new authorizable is required to have the following characteristics:

• User.isSystemUser() returns true.
• The system user doesn't have a password set and doesn't allow change the password.
• The principal name is generated by the system; it may be the same as userID.
• A given implementation may choose to keep system users in a dedicated location and thus may impose restrictions on the intermediatePath.

Parameters:

userID - A valid userID.

intermediatePath - An optional intermediate path to create the new system user. The implemenation may decide to reject intermediate paths if they violate an implementation specific requirement with respect to the location where systems users are being held.

The new system user.

isAutoSave

boolean isAutoSave()

If any write operations executed through the User API are automatically persisted this method returns true. In this case there are no pending transient changes left and there is no need to explicitly call Session.save(). If this method returns false any changes must be completed by an extra save call on the Session associated with this UserManager.

Returns:

true if changes are automatically persisted; false if changes made through this API (including method calls on Authorizable and subclasses are only transient and must be persisted using Session.save().

See Also:

autoSave(boolean)

autoSave

void autoSave(boolean enable)
       throws UnsupportedRepositoryOperationException,
              RepositoryException

Changes the auto save behavior of this UserManager.

Note, that this shouldn't be allowed in cases where the associated session is different from the original session accessing the user manager.

Parameters:

enable - If true changes made through this API will be automatically saved; otherwise an explicit call to Session.save() is required in order to persist changes.

Throws:

UnsupportedRepositoryOperationException - If the implementation does not allow to change the auto save behavior.

RepositoryException - If some other error occurs.
