Functions

func MakeCodec

func MakeCodec() *codec.Codec

MakeCodec generates the necessary codecs for Amino

func NewNameServiceApp

func NewNameServiceApp(logger log.Logger, db dbm.DB) *nameServiceApp

NewNameServiceApp is a constructor function for nameServiceApp 为应用添加一个简单的构造函数 添加以下逻辑： - 从每个所需模块中实例化所需的`Keeper`。 - 生成每个`Keeper`所需的`storeKey`。 - 注册每个模块的`handler`。`baseapp`的`路由器`的 `AddRoute()` 方法用来做这个。 - 注册每个模块的`querier`。`baseapp`的`queryRouter`中的`AddRoute()`方法用来做这个。 - 将`KVStores`挂载到`baseApp`的multistore提供的key值。 - 设置`initChainer`来定义初始应用程序状态。
