In lexical scoping, the scope of a variable is determined by its position or context in the code structure rather than its runtime behavior. To understand lexical scoping, consider the following example: Javascript 1 2 3 4 5 6 7 8 9 function outerFunction() { var outerVariable = 'Hi'...
In particular, we will go through various types of functions, will define how each type influencesvariables object of a context and what is contained in the scope chain of each function. We will answer the frequently asked questions such as: “is there any difference (and if there are, ...
有一定经验的javascript工程师也许会用过arguments、用过闭包、知道作用域,这一切的一切,都和execution context有关。 当我们进入一个函数调用的时候,解析器会为我们创建一个活动对象(Activation Object ),假设这里把这个活动对象叫做ac(为什么不叫ao呢,因为喜欢c)。然后做下面的事情: ...
SourceFunction是flink stream data sources的基本接口,这里头定义了run方法以及cancel方法,同时定义了SourceContext接口 SourceContext flink-streaming-java_2.11-1.6.2-sources.jar!/org/apache/flink/streaming/api/functions/source/SourceFunction.java 代码语言:javascript 代码运行次数:0 运行 AI代码解释 /** * Inte...
Each call to context.df.callActivity invokes an activity function called hello. You've also added the hello activity function that is invoked by the orchestrator. In the same file, you can see that it's taking a name as input and returning a greeting. An activity function is where yo...
javascript learning notes——function作者:adolsai 时间:March 12, 2014 分类:javascript 函数:一次定义,多次执行。js的函数调用还有一个特性,每次调用都会拥有另一个值——本次调用的this值(上下文/context)。函数可以作为对象的一个属性,称为对象的方法。当通过对象调用函数时,该对象就是此次调用的上下文。 //在...
