                                TigaseDBException

      `getData` method is a twin sister (brother?) of `setData(String, String, String)` method. It allows you to retrieve data stored with above method. It is data stored in given node with given key identifier. If there are no data associated with given key or given node does not exist given `def` value is returned.
      Parameters:
        `subnode` - a `String` value is path to node where pair `(key, value)` are stored.
        `key` - a `String` value of key ID for data to retrieve.
        `def` - a `String` value of default returned if there is nothing stored with given key. `def` can be set to any value you wish to have back as default value or `null` if you want to have back `null` if no data was found. If you set `def` to `null` it has exactly the same effect as if you use `getData(String)` method.
      Returns:
        a `String` value of data found for given key or `def` if there was no data associated with given key.
      Throws:
        `NotAuthorizedException` - is thrown when session has not been authorized yet and there is no access to permanent storage.

      This method retrieves list of all direct subnodes for given node. It works in similar way as `ls` unix command or `dir` under DOS/Windows systems.
      Parameters:
        `subnode` - a `String` value of path to node for which we want to retrieve list of direct subnodes.
      Returns:
        a `String[]` array of direct subnodes names for given node.
      Throws:
        `NotAuthorizedException` - is thrown when session has not been authorized yet and there is no access to permanent storage.

                                      TigaseDBException

      This method returns all data keys available in permanent storage in given node. There is not though any information what kind of data is stored with this key. This is up to user (developer) to determine what data type is associated with key and what is it's meaning.
      Parameters:
        `subnode` - a `String` value pointing to specific subnode in user reposiotry where data have to be stored.
      Returns:
        a `String[]` array containing all data keys found in given subnode.
      Throws:
        `NotAuthorizedException` - is thrown when session has not been authorized yet and there is no access to permanent storage.

                                      TigaseDBException

      This method allows to retrieve list of values associated with one key. As it is possible to store many values with one key there are a few methods which provides this functionality. If given key does not exists in given subnode `null` is returned.

        `subnode` - a `String` value pointing to specific subnode in user reposiotry where data have to be stored.
        `key` - a `String` value of data key ID.
      Returns:
        a `String[]` array containing all values found for given key.
      Throws:
        `NotAuthorizedException` - is thrown when session has not been authorized yet and there is no access to permanent storage.

    - #### setData

          public void setData(String subnode,

                       throws NotAuthorizedException,
                              TigaseDBException

      This method stores given data in permanent storage in given point of hierarchy of data base. This method is similar to `setData(String, String)` and differs in one additional parameter which point to user data base subnode where data must be stored. It helps to organize user data in more logical hierarchy.
      User data is kind of tree where you can store data in each tree node. The most relevant sample might be structure like typical file system or XML like or LDAP data base. The first implementation is actually done as XML file to make it easier test application and deploy simple installation where there is no more users than 1000.
      To find out more about user repository refer to `UserRepository` interface for general info and to `XMLRepository` for detailed explanation regarding XML implementation of user repository.
      Thus `subnode` is kind of path to data node. If you specify `null` or empty node data will be stored in root user node. This has exactly the same effect as you call `setData(String, String)`. If you want to store data in different node you must just specify node path like you do it to directory on most file systems:

           /roster

      Or, if you need access deeper node:

           /just/like/path/to/file

      If given node does not yet exist it will be automaticaly created with all nodes in given path so there is no need for developer to perform additional action to create node. There is, however method `removeDataGroup(String)` for deleting specified node as nodes are not automaticaly deleted.
      Parameters:
        `subnode` - a `String` value pointing to specific subnode in user reposiotry where data have to be stored.
        `key` - a `String` value of data key ID.
        `value` - a `String` actual data stored in user repository.
      Throws:
        `NotAuthorizedException` - is thrown when session has not been authorized yet and there is no access to permanent storage.

    - #### setDataList

          public void setDataList(String subnode,

                           throws NotAuthorizedException,
                                  TigaseDBException

      This method allows to store list of values under one key ID reference. It is often necessary to keep set of values which can be refered by one key. As an example might be list of groups for specific buddy in roster. There is no actual need to store each group with separate key because we usually need to acces whole list of groups.
      Parameters:
        `subnode` - a `String` value pointing to specific subnode in user reposiotry where data have to be stored.
        `key` - a `String` value of data key ID.
        `list` - a `String[]` keeping list of actual data to be stored in user repository.
      Throws:
        `NotAuthorizedException` - is thrown when session has not been authorized yet and there is no access to permanent storage.
