/**
    @file XMLPort.h
    @brief Declaration of the XMLPort helper classes and macros.

    XMLPort is a virtual function of every BaseObject. Every object can change this function.
    The XMLPort function gets called with an XMLElement, containing all attributes and
    subclasses the object gets from the levelfile.

    This file declares classes and macros to simplify XML-parsing.

    This is the same as XMLPortParam, but you don't need a savefunction (get-function). Therefore,
    this param won't be saved in an XML file, but you can add the attribute manually an it will be
    loaded.

    This might be helpful in cases, when you have several options to set a value, for example the
    rotation. You can set the rotation with a quaternion, but you could also use three angles.
    When saving the object, only one of both options has to be saved; this is, where this macro helps.

/**
    @brief This is the same as XMLPortParam, but for attributes in an extern class.

    @param paramname The name of the attribute
    @param loadfunction The function to set the attribute inside of the member object.
    @param loadfunction The function to get the attribute from the member object

    Sometimes you'll have a member object in your class, which has it's own load- and savefunctions.
    With this macro, you can simply use them instead of writing your own functions.

    @example
    Your class is called SpaceShip and this class has an object (myPilot_) of class Pilot. Pilot has a name
    and two functions, setName(name) and getName(). Now you want an attribute "pilotname" in your
    SpaceShip class. Instead of writing wrapper functions, you can simply use the XMLPortParamExtern
    macro:
    > XMLPortParamExtern(SpaceShip, Pilot, myPilot_, "pilotname", setName, getName, xmlelement, mode);

// XMLPortObjectExtended

/**
    @brief Declares a possible sub-object that can be added in the XML file.
    @param classname The name of the class that uses this macro
    @param objectclass The baseclass of objects that can be added
    @param sectionname The name of the subsection in the XML file that encloses the sub-objects ("" means no subsection)
    @param loadfunction The function to add a new object to the class
    @param loadfunction The function to get all added objects from the class
    @param xmlelement The XMLElement (recieved through the XMLPort function)
    @param mode The mode (load/save) (received through the XMLPort function)
    @param bApplyLoaderMask If this is true, an added sub-object only gets loaded if it's class is included in the Loaders ClassTreeMask (this is usually false)
    @param bLoadBefore If this is true, the sub-cobject gets loaded (through XMLPort) BEFORE it gets added to the main class (this is usually true)

    bApplyLoaderMask is usually false for the following reason:
    If the loaders mask says, for example, "load only SpaceShips" and you added weapons to the
    SpaceShips, then the Weapons will still be loaded (which is most probably what you want).
    Of course, if there are "standalone" weapons in the level, they wont be loaded.

    If bLoadBefore, an added object already has all attributes set (like it's name). This is most
    likely the best option, so this is usually true.

    @note
    The load- and savefunctions have to follow an exactly defined protocol.
    Loadfunction:
      The loadfunction gets a pointer to the object.
      > void loadfunction(objectclass* pointer);

    Savefunction:
      The savefunction gets an index, starting with 0. For every returnvalue != 0, the savefunction
      gets called again, but with index + 1. It's the functions responsibility to do something smart
      with the index and to return 0 if all objects were returned.
      > objectclass* savefunction(unsigned int index) const;

      Possible implementation:
        objectclass* savefunction(unsigned int index) const
        {
          if (index < number_of_added_objects_)
            return my_added_objects[index];
          else
            return 0;
        }

    @example
    Possible usage of the macro:
    > XMLPortObject(SpaceShip, Weapon, "weapons", addWeapon, getWeapon, xmlelement, mode, false, true);

    Now you can add weapons through the XML file:
    <SpaceShip someattribute="..." ...>
      <weapons>
        <Weapon someattribute="..." ... />
        <Weapon someattribute="..." ... />
        <Weapon someattribute="..." ... />
      </weapons>
    </SpaceShip>

    Note that "weapons" is the subsection. This allows you to add more types of sub-objects. In our example,
    you could add pilots, blinking lights or other stuff. If you don't want a subsection, just use "" (an
    empty string). The you can add sub-objects directly into the mainclass.
