dbus-glib 和 GDBus 的区别

• dbus-glib uses the , GDBus doesn‘t. Instead, it relies on GIO streams as transport layer, and has its own implementation for the the D-Bus connection setup and authentication. Apart from using streams as transport, avoiding libdbus also lets GDBus avoid some thorny multithreading issues.

        dbus-glib使用 ,GDBus不使用,而是依赖GIO流作为传输层,并且拥有一套自己实现的D-Bus连接设置和授权的方法.暂且不说GDBus使用流传输,

        不使用libdbus可以使GDBus没有一些多线程方面的问题.

• dbus-glib uses the GObject type system for method arguments and return values, including a homegrown container specialization mechanism. GDBus relies on the  type system which is explicitly designed to match D-Bus types.

       dbus-glib的方法参数和返回值使用Gobject类型系统,其中包含了一个特定结构的自有容器.GDBus依赖专为匹配D-Bus类型而设计的GVariant类型系统

• dbus-glib models only D-Bus interfaces and does not provide any types for objects. GDBus models both D-Bus interfaces (via the ,  and  types) and objects (via the ,  and  types).

       dbus-glib 只能提供D-Bus接口,不为对象提供任何类型,

       GDBus同时提供D-Bus接口(通过,  和  类型)和对象(通过,  和  类型)

• GDBus includes native support for the  (via the  type) and  D-Bus interfaces, dbus-glib doesn‘t.

       GDBus 为 (via the  type) 和  D-Bus接口,包含了本地支持,dbus-glib没有.

• The typical way to export an object in dbus-glib involves generating glue code from XML introspection data using dbus-binding-tool. GDBus provides a similar tool called  that can also generate Docbook D-Bus interface documentation. 

       dbus-glib中导出对象的典型方法是使用dbus-binding-tool根据XML内省数据生成代码,GDBus也提供了一个类似的工具叫做gdbus-codegen,这个工具也可以生成Docbook D-Bus接口文件.        

• dbus-glib doesn‘t provide any convenience API for owning and watching bus names, GDBus provides the  and  family of convenience functions.

       dbus-glib不提供战友和监视总线名字的方便的API,GDBus提供了 和 系列的方便函数.

• GDBus provides API to parse, generate and work with , dbus-glib doesn‘t.

        GDBus提供API来解析、生成 和 工作的内省XML，dbus-glib不提供。
