Class DummyRepository

  • All Implemented Interfaces:
    AuthRepository, DataSource, Repository, UserRepository

    public class DummyRepository
    extends java.lang.Object
    implements Repository, DataSource, UserRepository, AuthRepository
    DummyRepository is a class with all methods empty. They don't return anything and they don't throw exception. SessionManager requires a user repository to work properly but in some installations there is no need for user repository as authentication is done through external data source and user roster is pulled dynamically.

      • addDataList

        public void addDataList​(BareJID user,

                                java.lang.String key,
                                java.lang.String[] list)
        Description copied from interface: UserRepository
        addDataList method adds mode entries to existing data list associated with given key in repository under given node path. This method is very similar to setDataList(...) except it doesn't remove existing data.
        Specified by:
        addDataList in interface UserRepository
        Parameters:
        user - a BareJID value of user ID for which data must be stored. User ID consists of user name and domain name.
        subnode - a String value is a node path where data is stored. Node path has the same form as directory path on file system:
        /root/subnode1/subnode2
        .
        key - a String with which the specified values list is to be associated.
        list - a String[] is an array of values to be associated with the specified key.

      • userExists

        public boolean userExists​(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.
        Specified by:
        userExists in interface UserRepository
        Parameters:
        user - a BareJID value
        Returns:
        a boolean value
