What’s more, you can undo or redo your actions, perform basic editing operations (cut, copy, paste, delete), zoom in or out, and delete the selected component.ĭepending on the diagram type that you want to design, Violet UML Editor provides several tools built specifically for helping you insert various preset objects (e.g.
Plus, thanks to its multi-tabbed interface, you can work with several diagrams at the same time. The workspace is clean and intuitive and gives you the possibility to create one of the following diagram models: use case, class, activity, sequence, state, or object ones. You can copy it on any USB flash drive or other devices, and take it with you whenever you to need to build UML diagrams on the breeze, without having to go through installation steps.
VIOLET UML EDITOR CONSTRUCTOR PORTABLE
This is a portable program, so it is important to mention that it doesn’t leave any traces in the Windows Registry.
Since this is a Java-based utility, you should make sure you have previously installed the working environment on your computer, otherwise you cannot run the tool. Template class mean generic classes.Languages like C++, java, C# supports generic programming.Violet UML Editor is a lightweight application whose purpose is to help users design UML diagrams. Draw () and Erase () methods of Shape class is pure virtual function, so it is also shown as italics. Here Shape is an abstract class that is why it is shown in Italics. It is a “is a” relationship between two classes. In Inheritance relationship a class is derived from another class. Composition can occur when a class is a collection or container of other classes, but where the contained classes have a strong life cycle dependency on the container-essentially, if the container is destroyed, its contents are also destroyed Association differs from aggregation only in that it does not imply any containment.Ī window class contains a list of its shapesĪ car has it’s tiers, and the scope of tyre doesn’t depend on a car since a tyre can be used for another car alsoĪ Rectangle class has its style, which may be shared by other shapes also life time of style doesn’t depend on Rectangle class.Ĭomposition is the stronger form of aggregation. You may have confusion between aggregation and association. One class depends on another if the independent class is a parameter variable or local variable of a method of the dependent classĪggregation can occur when a class is a collection or container of other classes, but where the contained classes do not have a strong life cycle dependency on the container-essentially, if the container is destroyed, its contents are not. One object is aware of another it contains a pointer or reference to another object. “1.*” One or more instances (at least one)
“0.1” No instances, or one instance (optional, may) In a system a class may be related to different classes,following are the different relation ship. “Out” The parameter is an output parameter.ġ) Static members are represented as underlined.Ģ) Pure virtual functions are represented as italics. “Inout” The parameter is capable of both input and output. “in” The parameter is an input parameter. This post is meant for such people also it will be helpful for beginners, here I will explain the class diagram with C++ class example.Ĭlass diagram for the above class is shown below.ĭifferent visibility of the class can be represented as As you know a Class diagram is a diagram showing different classes in a system their attribute, operation and the relationship among different objects.Įven I have been using it for long time I always had confusion each time when I use it.
