I have to reverse engineer some classes from a Java application into a UML 2 class diagram. So far so good, I have found how to represent class templates for the whole class as proposed by Jon Skeet here: What is the correct way to represent template classes with UML? . With this info, I have reverse engineered a class like this: public class Foo<T> { //class fields and methods... } Now I have a dilemma trying to reverse engineer a class which only a method contains a generic parameter: public class OtherFoo { public <T extends Comparable<T>> boolean bar(T x, T y) { //fancy code goes here... }

目录 先看下面这张类图，包括了UML类图的基本图示法 1、类的表示 2、接口的表示 3、继承关系 4、实现接口 5、关联关系 6、聚合关系 7、合成（组合）关系 8、依赖关系 先看下面这张类图，包括了UML类图的基本图示法 ​ 1、类的表示 首先看那个‘动物’矩形框，它就代表一个类(Class)。 类图分三层，第一层显示类的名称， 如果是抽象类，则就用斜体显示 。第二层是类的特性，通常就是字段和属性。第三层是类的操作，通常是方法或行为。注意前面的符号， ‘+' 表示public, '-' 表示private,“#' 表示protected.” ​ 2、接口的表示 然后注意左下角的‘ 飞翔’，它表示一个 接口图 ，与类图的区别主要是 顶端有《interface》显示 。第一行是接口名称，第二行是接口方法。 接口还有另种表示方法，俗称棒棒糖表示法，就是唐老鸭类实现了‘讲人话’的接口。 ​ 3、继承关系 继承关系：使用 空心三角形 + 实线 表示 ​ 4、实现接口 实现接口：使用 空心三角形 + 虚线 表示 ​ 5、关联关系 企鹅需要“知道” 气候的变化。当一个类“知道” 另一个类的时候，可以使用 关联。关联关系用实线箭头表示。 （在“企鹅”类中有一个属性为“气候”对象） ​ 6、聚合关系 我们再来看大雁与雁群这两个类，大雁是群居动物， 每只大雁都是属于一个雁群，一个雁群可以有多只大雁

I have trouble understanding how the include and the extend relationships work. Let's say i have an online application for shopping. The application allows you to add/retrieve items from your cart without being authenticated. Here is the "order" scenario: The client clicks on the order button. The system checks if the user is authenticated. If the user is authenticated the system displays the purchase page otherwise the user is redirected to the authentication page. I would like to know if i the "authentication" use case is included in the "order" use case and if so why ? (I'm asking this

《大话设计模式》中讲述了UML类图的基本用法，做此笔记加深理解。 注：上图来源于《大话设计模式》 上图中设计的关键术语为：继承、实现、聚合、组合、关联、依赖。 要想弄清楚UML图的原理，必须深入理解上述六大术语的基本含义。 继承表示： //鸟类 class Bird { public: void layeggs() { } private: string color; }; //大雁类继承自鸟类 class wildGoose : public Bird { public: void layeggs() { } void fly() { } }; //鸭子类继承自鸟类 class duck : public Bird { void layeggs() { } void swimming() { } }; 继承关系为is-a关系，上述关系中，大雁、鸭子、企鹅均属于鸟类，则其继承自鸟类，其中，箭头方向所指动物类。 实现表示：（在C++中继承自抽象类也选用此种表示方式） //动物类 class Animal { public: //声明了纯虚函数的类，都成为抽象类。 virtual void live() = 0; private: string food; }; //鸟类继承自动物类 class Bird : public Animal { public: void layeggs()

I have developed an android application that communicates with a server. Through the application the user authenticates on the system that the server is running and after the server is able to send information to my application. I'm making a use case diagram (UML) for my application but I'm not sure if I should represent the server as an actor (external) or omit it from the diagram... I'm new in UML so the definitions are a little confusing to me at the moment... Can anyone help me with this? (Sorry if this is not the right place to put those kind of questions). First off, who is the diagram

Should a batch scheduled process (for example, a nightly process) be modeled as a Use Case? it is something the system should do, but there is not an Actor "using" the feature, because it is scheduled. Any suggestions? Thanks! We've defined a 'Scheduler' actor to model that scenario. The Scheduler usually has its own set of use cases which are batch jobs, or executables that need to run regularly, etc. For example, the Use Case can be written like "The Use Case begins when the current time is on the hour" for a job that runs 24 times a day. We try not to include too many of these cases because
