- Method Detail
  - login
```
void login()
```
    Checks whether the credentials in the authorization string match an existing User Account, and if so, creates an HTTP session. ### FIXDOC
    
    Parameters:
    
    authHeader - the authorization string containing the credentials. ### FIXDOC Formatted like a "Authorization" HTTP header value. That is, "Basic " appended by the Base64 encoded form of "{username}:{password}".
  - logout
```
void logout()
```
    Logs the user out. That is invalidating the session associated with the JSESSION ID cookie. For a "non-private" DM installation the response is 204 No Content. For a "private" DM installation the response is 401 Authorization Required. In this case the webclient is supposed to shutdown the DM GUI then. The webclient of a "private" DM installation must only be visible/usable when logged in.
  - getUsername
```
String getUsername()
```
    Returns the username of the logged in user.
    
    Returns:
    
    The username, or null if no user is logged in.
  - getUsernameTopic
```
Topic getUsernameTopic()
```
    Returns the "Username" topic of the logged in user.
    
    Returns:
    
    The "Username" topic (type dmx.accesscontrol.username), or null if no user is logged in.
  - getPrivateWorkspace
```
Topic getPrivateWorkspace()
```
    Returns the private workspace of the logged in user.
    Note: a user can have more than one private workspace. This method returns only the first one.
    
    Returns:
    
    The logged in user's private workspace (a topic of type "Workspace").
    
    Throws:
    
    IllegalStateException - if no user is logged in.
    
    RuntimeException - if the logged in user has no private workspace.
  - checkAdmin
```
void checkAdmin()
```
    Checks if the current user is a DMX admin and throws AccessControlException if not. Note: if invoked as "System" no AccessControlException is thrown.
    
    Throws:
    
    AccessControlException - if the current user is not a DMX admin.
  - createUserAccount
```
Topic createUserAccount(Credentials cred)
```
    Creates an user account. Only DMX admins are allowed to create user accounts.
    
    Returns:
    
    The "Username" topic of the created user account.
    
    Throws:
    
    RuntimeException - if the requesting user is not a DMX admin.
  - _createUserAccount
```
Topic _createUserAccount(Credentials cred)
                  throws Exception
```
    Creates an user account. This is a privileged method: no permissions are checked.
    Security: this method is not callable from outside as it has no REST interface. So the DMX platform is still secure. On the other hand, a 3rd-party plugin which provides a RESTful interface to this method is required to apply an additional authorization measure, e.g. a short-living access token sent via email.
    
    Returns:
    
    The "Username" topic of the created user account.
    
    Throws:
    
    Exception
  - createUsername
```
Topic createUsername(String username)
```
    Creates a Username topic and a private workspace. TODO: rename to createUsernameAndPrivateWorkspace?
    
    Returns:
    
    The created "Username" topic.
  - getUsernameTopic
```
Topic getUsernameTopic(String username)
```
    Returns the "Username" topic for the specified username.
    
    Parameters:
    
    username - a username. Must not be null.
    
    Returns:
    
    The "Username" topic (type dmx.accesscontrol.username), or null if no such username exists.
  - getWorkspaceOwner
```

    The username of the owner, or null if no owner is set.
  - setWorkspaceOwner
```
void setWorkspaceOwner(Topic workspace,
                       String username)
```
    Sets the owner of a workspace. ### TODO: should take an ID instead a topic. ### Core service must be extended with a property setter.
