问题 Does anyone manage to check OCL constraints on a class diagram modeled in Eclipse Papyrus ? I have definied a simple test profile with only one constraint on a stereotype attribute : {OCL} self.property > 0 The stereotype extends the Property metaclass so I applied it on a class attribute and I set the property of the stereotype to 0. But I never got an error with the Validation > Validate Model command from the context menu. Any help would be much appreciate. Thanks by advance. 回答1: I answer

问题 I have a child class which wants to add more functionality to a base class function, how can I represent that it also does the base class function not just the newly added functionality? 回答1: Interesting question. I tried that with Enterprise Architect. It did let me select the parent's operation but the display in the diagram did not change. It seems like you need to use notes for that: As you can see Class2 inherits from Class1 . The SD shows a call to Class2 's operation a() . The call to

问题 How do I draw a class in UML that uses a web service? 回答1: You could also use WSDL (Web Services Description Language) UML profile with the appropriate WSDL stereotypes. That would give for example: -------------------- | <<wsdl:service>> | -------------------- | MyWebService | -------------------- | | -------------------- | | -------------------- {URI="/MyWebService"} A full UML example involving many components of a web service would be: (source: xml.com) 回答2: Sounds like a sequence diagram

问题 What do the vertical rectangles signify in a UML sequence diagram? For example I want to know the meaning of the rectangle pointed to by the green arrow. Do the height of these rectangles mean anything? 回答1: The vertical rectangles denote execution specification . Execution specification is a part of object's interaction which represents period of object's lifetime when it is either doing some activity or simply waiting for the reply from other object. By some activity I mean sending messages

问题 Is there a formal language which can be used to capture the information present in an UML sequence diagram in to a text format, which is easy understandable by humans? In our place, often times software requirements are specified in terms of complex sequence diagrams which are difficult to review, verify for correctness and make changes. Also IMHO, programmers would prefer to implement from an unambiguous text representation of the requirements, rather than from sprawling multi page diagrams.

问题 I am thinking about creating a class diagram in Visual Studio. I notice that the Toolbox only appears to allow Association relationships between classes. Is it possible to create stronger relationships in the class diagram, i.e. Aggregation and Composition relationships? Also, is it possible to automatically create the class diagram from the code? 回答1: Great Question. First of all : Visual Studio (VS) Class Designer is not a CASE Tools (like Enterprise Architect and etc.). It is only a class

问题 I have some questions regarding the representation of the gui objects in uml class diagrams. For example if a have a class which extends the JFrame, then i will design the UML class diagram with the inheritance symbol, but in the JFrame, i do not need to write down all of it's class variables and methods, but only those whose my class will use right?? Second how will i represent that my class will use a specific layout manager? With the association symbol, i quess but i am not sure. Say for

问题 I'm dealing with an apparent simple issue. I'm writing a module similar to UML::Class::Simple but with some improvements. Summarizing, the idea is to retrieve a record card for each module in a given source, containing information about the Methods, Properties, Dependencies and Children. My current problem is getting Methods and Properties for each module. Let's see the code I've already written: use Class::Inspector; use Data::Dumper; sub _load_methods{ my $pkg = shift; my $methods = Class:

问题 Is there a way to generate UML Class diagram for swift programming language? I found that the Mac A&D tool claims to be able to scan the swift code and create a class diagram. And there is a video to introduce it. https://wn.com/swift_code_to_class_diagram Unfortunately, it is not free. I wonder if there is another free tool to generate class diagram automatically. Could you guys help me? Thanks in advance. UML class diagrams for Xcode (swift programming) 回答1: I recently found a free tool,
