Creating an overall class diagram with Doxygen - doxygen

I am trying to generate a Doxygen documentation for my Python project.
It seems like Doxygen does not provide an overall class diagram of the project including Association. It shows only inheritance for a single file.
Is there is a way I can generate an overall class diagram in doxygen?
Thanks a lot!

Doxygen does not generate class diagrams that contain "association" arrows.
These are the diagram types and my experience with them (stemming from C++):
CLASS_DIAGRAMS: Seems to be an old Doxygen option, superseded by CLASS_GRAPH, which contains more information. CLASS_DIAGRAMS often just show the class without anything else in my output, which is superfluous.
CLASS_GRAPH: This is actually an inheritance diagram, not a full class diagram (internally, it even goes by the name "inherit graph"). It doesn't show a diagram at all if a class is not a derived class or base class.
COLLABORATION_GRAPH: Shows base class, membership and template relations. Doesn't show "inherited by" or "used by" relationships. For a leaf class, the inheritance diagram (CLASS_GRAPH) is just a part of the COLLABORATION_GRAPH.
TEMPLATE_RELATIONS: Shows template relations in a similar style as inheritance, which is helpful for code using template specialization instead of inheritance, e.g. CRTP.
As you have a python project, did you try out Sphinx? sphinx.ext.inheritance_diagram comes included with the sphinx-doc distribution but also does not show other types of relations than inheritance.
A web search turned out https://pypi.org/project/sphinx-pyreverse/ which might be what you're looking for. I did not try it out myself.

Why does OWLViz only display "is-a" relationship?

Is is possible to display other properties, i.e. "hasTopping" etc.?
How to do that in OWLViz?
OWLViz only display the class hierarchies (both asserted and inferred class hierarchy). which is described using only "is-a" relationships.

Other properties may be displayed using the OWLPropViz plugin.

Showing classes in dependent ontologies when creating class hierarchy with OWL API

I want to create a class hierarchy of the classes in an ontology using OWL API, similar to what you might see if you loaded an ontology in a tool such as Protege.
An example of how to do this may be found here: http://sourceforge.net/p/owlapi/mailman/message/27600103/.
As you can see, it seems difficult to reproduce the Protege hierarchy precisely using OWL API, and I am wondering if there is an example which will reproduce Protege's behaviour or if the fundamental reasons for not being able to do so may be clarified so an alternative approach may be found. I have had similar problems to the author of the post above, in that I can't seem to consistently reproduce the hierarchy shown by Protege by recursively going through the classes and subclasses, starting at owl:Thing, in order to create the full class hierarchy.
I need to:
Create not only the class hierarchy structure of the top level ontology being parsed, but also show the hierarchical relationships with classes in dependent ontologies, as Protege does. Protege shows the classes in the top level ('active') ontology in bold, with classes taken from dependent ontologies in normal print.
Create the hierarchy consistent with that shown by Protege for the same active ontology. I am assuming the hierarchy shown by Protege is correct?
I am happy to post code snippets and examples if desired, please do ask.
The Protégé hierarchy is not a plain hierarchy - Protégé does some reasoning to enrich it, at the behest of its users.
If you have code snippets you wish to refine, it would be useful to see the code, an ontology snippet and what you wish the result to look like - for example, a Protégé screenshot. Then it will be easier to refine the answer.

Enterprise Architect - How to create classes from sequence diagrams?

I have experience with StarUML and Jumli. At my current company we have a Professional license for EA 9.2.
When I design a program, I start with creating Use Cases. Then from every Use Case, I create a Sequence Diagram. And from the Sequence Diagrams, almost every Lifeline-object will become a class (and all messages will become a method). With StarUML and Jumli this wasn't a problem.
But I cannot find a way in EA to convert the Lifeline objects into classes.
I tried to read the help from Sparx, but to me it is not really helpful. Their 'tutorial' is not a tutorial, but actually just another help file with lots of blah blah.
Can anyone tell me how to do this? Or are there any really helpful links?
It IS possible, but only in one a bit hidden way. First I'll tell you about the alternative ways:
you have a conceptual error here. Timelines in Sequence diagram are not classes, but objects. So, they can't become classes.
Of course, a tool could have a function to create a class according to an object, as VP UML has. Obviously, EA has not such feature.
On the contrary, it is not a problem to drop a class on the sequence diagram to become a timeline. But EA has some conceptual problems with it, too. You have to make it an object here. Look also this.
On the other hand, there should be no problems to drop a timeline to the object diagram, but in EA it IS a problem - the object-timeline remains the timeline even on the Object diagram. That is obviously non-convenient and ununderstandable, but it is so. Obviously, it is one of these bugs that are called "features".
The same is behaviour of the timeline if we drop it on the Class Diagram. We even can't connect this object to a class by generalization - EA considers such connection as a rules breaking one.
And finally, how you CAN connect the timeline/object to a class. Right-click the timeline on the sequence diagram or its copy object on the class diagram. Go to Advanced. Choose Instance Classifier - the first menu item. There you can choose an existent class or even create a new one. And the object/timeline will belong to this very class.
You can't reach this feature from the Project Browser. It is obviously, another "feature" of the EA.
In a spec-adherent UML tool, one can assign classes (among other things) to a lifeline. I think that is why you are having difficulty converting lifelines into classes: they aren't the same kind of thing! Try creating classes first and assigning them to lifelines.
To transform sequence model into class model right-click on the package choose "Transform Current Package" => Check DDL => Select Transform
I hope this helps.

How can I describe these types in UML class diagram?

I'm making a class diagram for a project.
How can I describe vectors, lists, files or unsigned types?
I would like to make a detailed diagram so I need to specify the types of the members and the input/output parameters of the methods.
Thank you all!
For more detailed description of the inner structure of the class you need a Composite Structure Diagram. There you can describe your methods as "ports". And your fields as attributes. You can show there really almost everything!
For detailed description of the specific instances of the class and their mutual behaviour you need an Object diagram.
At the links applied you can see a bit how to make them. But take it as a start only.
The class diagram is too common to describe the inner structure of the class. It is tooled for the description of the inter-classes relations. So, you can put your information into the model of the class, but some of it won't be seen on the diagram. But I would advise you to start from the class diagram and make it as detailed as it can show and only later go to more detailed diagrams. Maybe you won't need them after all.
Edit:
You can make a port on the border of your class, name it fileName and connect it to io interface you use. (Composite Structure Diagram only)
As for vector/list, it is easier, and could be done in a Class Diagram. If you want to show that some attribute is a vector or list, simply write: someAttr:List or put a List block on the diagram, draw association to it and name its end "someAttribute". You could do it with File, too, but there you should draw more, I think, to show the used io interface.
For showing attributes in class diagram also look here.
You should use an uml class diagramm. [Link][1]
In a class diagramm you can relate class members with types, functions with parameters and signatures.

(Somebody can format this? IMHO SO app can not handle links..)
Your question is not clear to me. There are two variants:
you need to define what type of collections (vector, list etc) in specific programming language should be used to implement multicity element ([N], [0..N] ordered or unordered, unique or nonuniqu)
It is not possible to explicitly define in UML. You can only declare, what type it is. For example in note or constraint
You need simply define types of collection
Use ordinary class or DataType element to define
Standard syntax for member (attribute, port etc.) is following: +name:Type[Multiplicity]{contraints}
The same syntax is used for parameters (all types) of operation (methods in programming language)

How is a class diagram converted into code?

I was self-studying various UML diagrams and I understood most of them except for Class Diagram and Object Diagram.
I can not get my head around how they wil be converted into code.
The trick that I learnt is this: all nouns become classes and verbs become methods of the classes.
All good till there but after that, how is the diagram converted into code?
Have a look at a diagram here that I got from the internet:
So, assuming that the language is Java, how will you code a software based on this?
A UML diagram solely describes the internal architecture of a given piece of software.
The information contained in your UML diagram is therefore:
What classes are contained
What methods and properties do they contain
How do they relate to each other
Each block with a header ("Train" for instance ) represents a class, listing its properties and methods.
As such the UML diagram does not state anything about a GUI or how the user interacts with the software. It is up to you or a UI/UX designer to create an interface you can implement, that uses the functionality outlined in this UML diagram.
You can think of a UML diagram as a description of the architecture of a piece of software, that is very shallow but is well suited for an overview of the project.
It is not a recipe.
I hope this was useful to you.
When you have a class diagram, you have a representation of the classes (and its members) that you should have in code.
So, your noun/verb analysis (what you were talking about), has already been done when you have a class diagram.
A class diagram is just a visual representation of your classes, converting them to code is just easy if you know the syntax of the language that you want to use.
