This tutorial sees the addition of the BeginState() and EndState() events to the Dialog state as well as the creation of the Greeting state which extends the base Dialog state in order to show how state inheritance works. 为了展示状态继承是如何工作的,在本指南中我们会看到向Dialog状态中添加了...
Flatmap正常情况下实现FlatMapFunction然后重写flatMap<>方法,为了更丰富的功能另一种方式是继承RichFlatMapFunction<IN,OUT> ,多了一个初始化方法open只会运行一次。用Rich目的就是用来注册状态 ValueState保存的是对应的一个key的一个状态值 在flatMap中对上面的countAndSum进行业务逻辑操作 SparkStreaming中updateStat...
class MapStateFunction extends RichFlatMapFunction[UserBehavior, (Long, String, Int)] { // 指向MapState的句柄 private var behaviorMapState: MapState[String, Int] = _ override def open(parameters: Configuration): Unit = { // 创建StateDescriptor val behaviorMapStateDescriptor = new MapStateDescri...
如果Data Stream是Keyed Stream,则连接到Broadcasted Stream后,添加处理ProcessFunction时需要使用KeyedBroadcastProcessFunction来实现,下面是KeyedBroadcastProcessFunction的API,代码如下所示: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 publicabstractclassKeyedBroadcastProcessFunction<KS,IN1,IN2,OUT>extendsBaseBro...
When processing callbacks and conditions, transitions will use their name to retrieve the related callable from the model. If the method cannot be retrieved and it contains dots, transitions will treat the name as a path to a module function and try to import it. Alternatively, you can pass ...
Design and construction of a new class of scaffolding-like materials comprising infinite polymeric frameworks of 3D-linked molecular rods. A reappraisal of the Zn(CN)2 and Cd(CN)2 structures and the synthesis and structure of the diamond-related frameworks [N(CH3)4][Cu1Zn11(CN)4] and Cul...
