    - #### initFromCommand

          public void initFromCommand(Packet packet)

      Description copied from interface: `RepositoryItem`
      The method used for handling ad-hoc commands. After a user fills all given field the ad-hoc command packet is passed back to the item to initialize it with data. Similar method to initFromElement(), but the data source is different.
      Specified by:
        `initFromCommand` in interface `RepositoryItem`
      Overrides:
        `initFromCommand` in class `RepositoryItemAbstract`
      Parameters:
        `packet` - with ad-hoc command filled by the user.

    - #### initFromElement

          public void initFromElement(Element elem)

      Description copied from interface: `RepositoryItem`
      The item can be also initialized from a more complex repositories: XML repository or SQL database. In such a case more complex representation is prefered, possibly carrying more information about the item. The method is called to initialize the item with a data parsed from an XML representation of the repository.
      Specified by:
        `initFromElement` in interface `RepositoryItem`
      Overrides:

      Parameters:
        `propString` - is a property string to initialize the RepositoryItem.

          public Element toElement()

      Description copied from interface: `RepositoryItem`
      Item data can be stored in a more complex form than a simple property string. The XML Element can contain much more detailed information about the element than the simplified form and is used to store the repository item in more advanced repositories then just property file. XML repository or SQL database can keep many records for repository item with as much detailed information as needed.
      Specified by:
        `toElement` in interface `RepositoryItem`
      Overrides:
        `toElement` in class `RepositoryItemAbstract`

          public String toPropertyString()

      Description copied from interface: `RepositoryItem`
      The item can be initialized based on the data loaded from a configuration file. In such a case the item representation is usually very simplified as a list of parameters separated by a marker. Please note, usually each item is separated from another with a comma, therefore do not use a comma in the item property string. Double collon is commonly used alternative.
      Returns:
        a property string representing the repository item in a simplified form.
