也就是说,当您调用某个选择器时,它使用选择条件和日期范围条目来选择目标。
That is, when a selector is invoked, it selects a destination using the selection criteria and date range entries.
在练习1中,您将创建一个具有一个缺省目标和两个日期范围目标的选择器。
In exercise 1, you will create a selector that has one default destination and two date range destinations.
您可以在运行时更新或修改选择器及其对应的日期范围的目标,而无需重新部署初始应用程序。
