This is different question to saving data, the serialization support uses
completely different mechanism.

Have a look at include/osg/ValueObject for the get/set methods for the
ValueObject/GetValueVisitor/SetValueVisitor.

Or... just use the template methods in osg::Object i.e.

 // set value
 int count;
 object->setUserValue("count", count);

  // get value
  object->getUserValue("count", count);

The later returns true of the object has a "count" value object of the same
type as the parameter passed in.  You need to take care here as:

  unsigned int value;
  object->getUserValue("count", value);

Will return false for the above setting using an int.

Robert.
