Detailed Description
\inmodule
QtDBus
The QDBusMetaType class allows you to register class types for marshalling and demarshalling over D-Bus. D-Bus supports a very limited set of primitive types, but allows one to extend the type system by creating compound types, such as arrays (lists) and structs. In order to use them with Qt D-Bus, those types must be registered.
See Qt D-Bus Type System for more information on the type system and how to register additional types.
See also Qt D-Bus Type System, qDBusRegisterMetaType(), QMetaType, QVariant, and QDBusArgument.

[static]
bool QDBusMetaType::demarshall(const QDBusArgument &arg, QMetaType metaType, void *data)
\internal
Executes the demarshalling of type metaType (whose data will be placed in data) from the D-Bus marshalling argument arg. Returns true
if the demarshalling succeeded, or false if an error occurred.
[static]
bool QDBusMetaType::marshall(QDBusArgument &arg, QMetaType metaType, const void *data)
\internal
Executes the marshalling of type metaType (whose data is contained in data) to the D-Bus marshalling argument arg. Returns true
if the marshalling succeeded, or false if an error occurred.
[static]
void QDBusMetaType::registerCustomType(QMetaType type, const QByteArray &signature)
\internal
Registers the meta type type to be represeneted by the given D-Bus signature.
This is used in qdbuscpp2xml for custom types which aren't known to the C++ type system.
[static]
void QDBusMetaType::registerMarshallOperators(QMetaType metaType, MarshallFunction mf, DemarshallFunction df)
\internal
Registers the marshalling and demarshalling functions for meta type metaType.
