public class XMLRepository
extends Object
implements AuthRepository, UserRepository
```
Class XMLRepository is a XML implementation of UserRepository. It uses tigase.xml.db package as repository backend and uses Bridge design pattern to translate XMLDB calls to UserRepository functions.

    Specified by:
    
    updatePassword in interface AuthRepository
    
    Parameters:
    user - a BareJID value
    password - a String value
    
    Throws:
    
    UserNotFoundException
    
    TigaseDBException - if an error occurs
    
    UserExistsException
  - userExists
```
public boolean userExists(tigase.xmpp.BareJID user)
```
    Description copied from interface: UserRepository
    
    Method userExists checks whether the user (or repository top node) exists in the database. The method doesn't throw any exception nor it creates the user in case it is missing. It just checks whether the user is already in the database. Please don't overuse this method. All other methods throw UserNotFoundException exception in case the user is missing for which you executed the method. The exception is thrown unless userAutoCreate property is set to true. In such case the exception is never thrown and the methods are executed for given parameters prior to creating user entry if it is missing. Therefore this method should be used only to check whether the account exists without creating it.

    Parameters:
    user - a BareJID value
    
    Returns:
