After all the operators have been evaluated, what remains is a single data value that represents the result of the computation. For example, given the expression.
在所有的操作符被赋值以后,最后剩下的将会是一个代表了计算结果的单独的数值。
For example, if you wanted to add some code that monitored what method was being called, its parameters, and how an internal computation or algorithm is working, then you can define a custom probe.
例如,如果你想增加一些代码来监视什么方法被调用,它的参数以及它内部的算法和计算是怎样工作的,那么你就可以自己定制一个探针。
For example, if there is a use case to make a room booking, there must also be computation rules to determine the room charges.
例如,如果有一个用例是进行一个房间预订,也必须有一个计算规则来确定房间费用。
