Class Diagram

4/1/2011 12:00:15 AM | Dušan Rodina | 5566x

Category: Structure diagram

UML diagram, which describes the structure of a system by showing the system's classes, their attributes, and the relationships among the classes.

The class element consists of three sections:
- Name
- Attributes – represent fields of a class
- Operations – represent methods of a class
The visiblity of attributes and operations can be specified as:
- Private (-)
- Protected (#)
- Package (~)
- Public (+)

Class Diagram Elements

Class Diagram can consist of these types of elements:
-Package
-Class
-Interface
-Enumeration
-Table
-Signal
-Collaboration
-Association (unidirectional, bidirectional, composition, aggregation, and custom ones)
-N-ary association
-Generalization
-Realization
-Dependency
-Containment

Multiplicity of attributes 12/14/2011 6:38:03 AM

I could not find multiplicities of attributes, as you can see here the "1" in [] after heap.

It is not yet supported. I will add it in version 5.0. The code will be completed this year - I'm planning the release for January 9th, 2012.

Default visibility not working & shortkeys 10/5/2011 2:32:22 AM
0 + - 0

Hello,

We are trying this tool. It looks nice.

I have set the default visibility to protected. But all items in a classdiagram are set to private.

Could this be solved?

Are there any shortkeys for making a diagram. This would be very handy:

- repeat latest class

- repeat latest connector

Hello,

the default visibility setting has not retroactive effect. It is applied only on newly created items. I could add a command for "batch" change of visibilities.

Thank you for these tips. I'll add key shortcuts for diagrams and also repeat-options in the next major version (5), which should be released soon - I'll finish it within few weeks - certainly this year.

How do you make the lines connect like in the picture for the subclasses

You can make it this way:

I will try to make it easier in future versions.

Dušan,do you plan to include the reverse engineering capability (C++ to UML) in your software?

Yes, I plan it. Maybe it will be not in the first release of version 5, but I suppose that this feature appears in one of its minor versions (5.x).

Dušan, I have the following problem. When I open my preliminarily saved class diagram the relations lines & arrows ("use" stereotype) somewhat dislocated. That greatly clutters the plot. Is there any way to fix them? Thank you for your job.

Were the ends of the relationship properly connected with classes before saving? When the end points are disconnected, they will be connected back after loading. I will change this behavior in the next version - the relation will be adjusted immediately after completing the dragging.

Yes, they were! The problem is that, I have several classes which use the other

class. I connect them by the dependency relation. I put together all the arrows

as if there's only one arrow. That approach orders the diagram. But when I open

my diagram all the arrows don't lie upon the initial arrow. Although the relation

isn't broken between classes...

In the next release, I'll implement a improvement, which should avoid this problem.

Dušan, great job!

How can I get the generated C++ code with #include instruction?

I use a Class Diagram. For example I have 2 classes. What type of connection should I use between 2 classes?

Thank you.

Unfortunately, generation of #include is not you supported. Possibilities of source code generator will be enhanced in the next major version 5.

I love SIM Is there any way to remove visibility in the classes?

My lecturer has just pinged me for having + and - in my diagram

Thanks.

Unfortunately, it isn't yet possible. However, I can add this option in the next release.

Option for showing/hiding the visibility was added in the new version 4.97.

Thanks for this user friendly software. May I know if we are able to add properties instead of public field?

You are welcome.

It is not yet possible, but I plan to add this possibility in version 5.

Creating a class diagram from a schema 10/26/2010 9:44:03 PM
2 + - 1

First, thank you very much for allowing us to use this great software. Excellent job guys!!

I was wondering if there is a way to import the data and relations from a schema or from a text based file to create the appropriate class diagram. As of now, i am copying and pacing the attribute into each class !! and it is a tedious process :)

Thank you all
