Feasibility of getting Maven aggregator pom to inject properties into module poms (not using inheritance)

最后都变了- 提交于 2020-02-27 08:15:39
问题 A bit of a feasibility question for you regarding Maven. Particular, on whether we can define properties in an aggregating pom and then inject them into the referenced modules, thus allowing that module to locally overwrite the default properties defined in the inheritance hierarchy. If you're interested in specifics I'll describe my setup. Before I do though, let me just say that we have discussed our project structure as a team extensively and it fits our needs very well. We are not looking

问题 I want to make an upsert call to update as well as insert my data in nested array of mongo db. This is my mongo document. { "_id" : "575", "_class" : "com.spyne.sharing.SpyneShareUserProject", "spyneSharePhotoList" : [ { "_id" : "fxLO68XyMR", "spyneShareUsers" : [ { "_id" : "chittaranjan@eventila.com", "selectedByClient" : false }, { "_id" : "chittaranjan@gmail.com", "selectedByClient" : false } ] }, { "_id" : "nVpD0KoQAI", "spyneShareUsers" : [ { "_id" : "chittaranjan@eventila.com",

Aggregate rows by shared values in a variable

问题 I have a somewhat dumb R question. If I have a matrix (or dataframe, whichever is easier to work with) like: Year Match 2008 1808 2008 137088 2008 1 2008 56846 2007 2704 2007 169876 2007 75750 2006 2639 2006 193990 2006 2 And I wanted to sum each of the match counts for the years (so, e.g. the 2008 row would be 2008 195743 , how would I go about doing this? I've got a few solutions in my head but they are all needlessly complicated and R tends to have some much easier solution tucked away

想走? 可以! 先买票 迭代器模式

20.1 乘车买票 不管你是谁 20.2 迭代器模式 提供一种方法顺序访问一个聚合对象中各个元素。而又不暴露该对象的内部表示, 一个聚集对象,不管这些对象是什么都需要遍历的时候,就应该考虑用迭代器模式, 需要对聚集有多种方式遍历时,可以考虑用迭代器模式, 20.3 迭代器实现 namespace 迭代器模式 { class Program { static void Main(string[] args) { ConcreteAggregate a = new ConcreteAggregate(); //公交车,即聚集对象, a[0] = "大鸟"; a[1] = "小菜"; a[2] = "行李"; //新上来的乘客,即对象数组, a[3] = "老外"; a[4] = "公交内部员工"; a[5] = "小偷"; Iterator i = new ConcreteIterator(a); //售票员出场,看好上车的有哪些人,即声明迭代器对象, object item = i.First(); while (!i.IsDone()) { Console.WriteLine("{0} 请买车票!", i.CurrentItem()); i.Next(); } Console.Read(); } } //Iterator迭代器抽象类, abstract class Iterator

理解 JMeter 聚合报告(Aggregate Report)

理解 JMeter 聚合报告(Aggregate Report) Aggregate Report 是 JMeter 常用的一个 Listener ,中文被翻译为 “ 聚合报告 ” 。今天再次有同行问到这个报告中的各项数据表示什么意思,顺便在这里公布一下,以备大家查阅。 如果大家都是做 Web 应用的性能测试,例如只有一个登录的请求,那么在 Aggregate Report 中,会显示一行数据,共有 10 个字段,含义分别如下。 Label :每个 JMeter 的 element (例如 HTTP Request )都有一个 Name 属性,这里显示的就是 Name 属性的值 #Samples :表示你这次测试中一共发出了多少个请求,如果模拟 10 个用户,每个用户迭代 10 次,那么这里显示 100 Average :平均响应时间——默认情况下是单个 Request 的平均响应时间,当使用了 Transaction Controller 时,也可以以 Transaction 为单位显示平均响应时间 Median :中位数,也就是 50 % 用户的响应时间 90% Line : 90 % 用户的响应时间 Note :关于 50 % 和 90 % 并发用户数的含义,请参考下文 http://www.cnblogs.com/jackei/archive/2006/11/11
