Description

This mixin can be added to a TpBaseConnection subclass to implement the Contacts interface in a generic way.

To use the contacts mixin, include a TpContactsMixinClass somewhere in your class structure and a TpContactsMixin somewhere in your instance structure, and call tp_contacts_mixin_class_init() from your class_init function, tp_contacts_mixin_init() from your init function or constructor, and tp_contacts_mixin_finalize() from your dispose or finalize function.

To use the contacts mixin as the implementation of TpSvcConnectionInterfaceContacts, in the function you pass to G_IMPLEMENT_INTERFACE, you should call tp_contacts_mixin_iface_init. TpContactsMixin implements all of the D-Bus methods and properties in the Contacts interface.

To add interfaces with contact attributes to this interface use tp_contacts_mixin_add_contact_attributes_iface:
