* @brief Class for accurately representing D-Bus data types
*
* The TQT_DBusData class can be compared to TQt's TQVariant class, but
* specialized to contain data types used in D-Bus messages.
*
* Like TQVariant objects of TQT_DBusData use implicit sharing, i.e. copying
* a TQT_DBusData object is a cheap operation and does not require that the
* content itself is copied.
*
* Depending on the #Type of the object, the content can be a recursive
* construct of TQT_DBusData objects, e.g. a #List can contain elements that are
* containers themselves, e.g. #Map, #Struct, #Variant or even #List again.
