public interface UserRepository extends Repository
UserRepository interface defines all functionalities required to store user data. It contains adding, removing and searching methods. User repository is organized as hierarchical data base. It means you can add items to repository on different levels like files in file systems. Instead, however of working with directories you work with nodes. You can create many levels of nodes and store data on any level. It helps to organize data in more logical order.

    • userExists

      boolean userExists(BareJID user)
      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:
      a boolean value
