Interface UserManager

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.

getAuthorizableByPath

Authorizable getAuthorizableByPath(String path)
                                   throws javax.jcr.UnsupportedRepositoryOperationException,
                                          javax.jcr.RepositoryException

In accordance to Authorizable.getPath() this method allows to retrieve an given authorizable by it's path.

Parameters:

path - The path to an authorizable.

Returns:

Authorizable or null, if not present.

Throws:

javax.jcr.UnsupportedRepositoryOperationException - If this implementation does support to retrieve authorizables by path.

findAuthorizables

Iterator<Authorizable> findAuthorizables(String relPath,
                                       String value)
                                         throws javax.jcr.RepositoryException

Returns all Authorizables that have a property with the given relative path (or name) that matches the specified value.

If a relative path with more than one segment is specified only properties exactly matching that patch will be returned. If, however, a name is specified all properties that may be retrieved using Authorizable.getProperty(String) will be searched for a match.

Parameters:

relPath - A relative property path or name.

value - A string value to match.

Returns:

All Authorizables that have a property with the given name exactly matching the given value.

                       javax.jcr.RepositoryException

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 javax.jcr.UnsupportedRepositoryOperationException,
                     javax.jcr.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:

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

javax.jcr.RepositoryException - If some other error occurs.
