init
Description:
public static void init (ObjectClass cls, size_t offset)
Initialize the class cls to use the D-Bus Properties mixin.
The given struct member, of size sizeof(TpDBusPropertiesMixinClass), will be used to store property implementation information.
Each property and each interface must have been declared as a member of a GInterface implemented by cls, using
svc_interface_set_dbus_properties_info.
Before calling this function, the array interfaces must have been placed in the
DBusPropertiesMixinClass structure; if it would be
empty, it may instead be null.
This function should be called from the class_init callback in such a way that it will only be called once, even if the class is subclassed.
Changed in 0.7.9: TpDBusPropertiesMixinClass::interfaces may now be null, which means that only interfaces whose properties are
set up using tp_dbus_properties_mixin_implement_interface will be used.
Changed in 0.7.15: offset may now be 0, in which case the
DBusPropertiesMixinClass can be omitted from cls
. It is treated as if it were present, but with all fields (including TpDBusPropertiesMixinClass::interfaces) being null, so
only interfaces whose properties are set using tp_dbus_properties_mixin_implement_interface will be used.
Parameters:
| cls |
a subclass of ObjectClass |
| offset |
the offset within |
