Class Diagrams, Stereo Types

How do I set the stereotype of a class in a UML class diagram. I have tried setting the visual properties to display stereotypes but JDev only displays <<class>> for the stereotype. I would like to be able to assign the stereotypes entity, controller and boundary and have the shape of the diagram change to reflect those stereotypes. Can I do this with JDeveloper?

The current version of JDeveloper does not support user defined stereotypes, and displays only the standard stereotypes (class, interface, package, association, etc). User defined stereotypes is something we are looking into for a future version.
Thanks, Guus (JDev PM)

VS2013.4 Class Diagram inheriting from a base type (how do I)

Hi Folks,
I am creating a VS2013.4 class diagram and one of my classes inherits from a base class System.Configuration.ProviderBase.
In VS2010 there is a way to do this and the class new class would show (Abstract Class -> ProviderBase) in its description. Is there a way to
When I look at the properties for the class there is no property specifying inheritance. In VS2010 there is an 'Inherits' property.

If the User-Agent contains "Fennec/" then it is Firefox for mobile. If it contains "Android" then it is running on an Android device.
We have an open request to add more device info to the User-Agent header. For details, see:
https://bugzilla.mozilla.org/show_bug.cgi?id=625238
We'll consider this request, but we must balance it against user privacy, and attacks like browser fingerprinting. For now, in cases where you don't detect a known device from the User-Agent header, you can ask the user instead (for example, have them choose from a list of devices). This will also benefit Android users who have changed their browsers' User-Agent headers for various reasons.

Abstract Class and polymorphism - class diagram

Hi,
]Im trying to draw a class diagram for my overall system but im not too sure how to deal with classes derived from abstract classes. I'll explain my problem using the classic shape inheritance senario...
myClass has a member of type Shape, but when the program is running shape gets instantiated to a circle, square or triangle for example -
Shape s = new circle();
since they are shapes. But at no stage is the class Shape instantiated.
I then call things like s.Area();
On my class diagram should there be any lines going from myClass directly to circle or triangle, or should a line just be joining myClass to Shape class?
BTW - is s.Area() polymorphism?
Thanks,
Conor.

Sorry, my drawing did not display very well.
If you have MyClass, and it has a class variable of type Shape, and the class is responsible for creating MyClass, use Composition on your UML diagram to link Shape and MyClass.
If you have MyClass, and it has a class variable of type Shape, and the class is created elsewhere, use Aggregation on your UML diagram to link Shape and MyClass.
If you have MyClass, and it is used in method signatures, but it is not a class variable, use Depedency on your UML diagram to link Shape and MyClass. The arrow will point to Shape.
Shape and instances of Circle, Triangle, Square, etc. will be linked using a Generalization on your UML diagram. The arrow will always point to Shape.
Anything that is abstract (class, method, variable, etc.) should be italicized. Concrete items (same list) should be formatted normally.
BTW, the distinction between Composition, Aggregation and Dependency will vary from project to project or class to class. It's a gray area. Just be consistent or follow whatever guidelines have been established.

Ternary Association In a class diagram

Hi
Please help. I need to depict a ternary association icon between 3 Classes in my Class diagram.
I am using Java Studio Enterprise 8's UML tool.
The modeling palette does not make provision for this type of association.
Is there a way to depict the ternary association icon, or is there an update for the Modeling palette in the class diagrams?
It is the little diamond, looks the same as the decision icon.

I filed one for neext release http://www.netbeans.org/issues/show_bug.cgi?id=79744
It's unlikely functionality will be added in patch to jse8.

Creating OO database objects by using class diagrams in JDeveloper

I am new to use JDeveloper. I create UML class diagrams (using Entity Object) in JDeveloper, which has inheritances and associations, and then choose Create Database Objects... try to create oo database, but it only create some tables in the database, not any object types ... .
What do I missed? Or I have to create those oo database objects manually?
Thanks.

Tony,
You can use database object types with BC4J, but only to implement BC4J domains (these can map to object types).
For performance reasons, it is less practical to generate a table of object types for a complete EO. Most users view the BC4J layer as the 'pure' OO model, and map to a relational datamodel for optimal performance.
Below some steps to create a DB object type for a domain:
You can create Oracle Object Types in the database by creating a business component domain and then forward generating the database object. Forward generation of object tables from entity objects is not supported. To forward generate an Oracle Object Type from a new domain: In the System Navigator, right click on your business component package and choose Create Domain. When the Domain Wizard opens, review the information on the Welcome page and click Next. Enter a Name and Package for the domain or accept the defaults. Select the checkbox for Domain for an Oracle Object Type. Do not select any items on the Available Types list, as you are creating a new one. Enter the name of your new type in the Selected Type field. Click Next. On the Settings page, click New. Provide a name in the New Domain Attribute box. Select the appropriate Java type a[i]Long postings are being truncated to ~1 kB at this time.

JDev Java class diagrams - how to associate 2 classes to parent via Map?

I am using 9.0.5.1 and working on some simple Class diagrams. I have learnt how to use the @associates javadoc tag and association editor to get associations displayed between classes that use Collections. However, it seem that I cannot associate the classes used for the "key" and "value" in member Map. Only a single association per member variable appears to be supported. Is this possible?
In case the above doesn't make sense, here is the code from the class with the Map member:
* @associates <{score.ContentItem}>
* @associates <{score.ScoreConsolidator}>
protected Map descriptionMap = new HashMap();
The diagram tool only seems to recognize the last @associates tag. I have tried a few syntaxes for refering to multiple classes to no avail.
Thanks
Drew

Drew,
Your correct, we do only support one associates tag. The associates tag indicates the collection type of the association, and only the first associates tag will be read.
The best way to indicate that an association is indexed, or keyed, by a certain type is to draw a dependency between the association line and the key, or index, type.
Thanks,
Geoff

Underlining in class diagrams

Can anyone please explain the following?
1) I have a class diagram where two of the three operations are underlined. The third operation is not underlined.
2) In a second class diagram, all four attributes are underlined. None of the operations are underlined.
(In the BankAccount class diagram in the tutorial, none of the attributes or operations are underlined.)

From the IDE Help:
http://www.netbeans.org/source/browse/*checkout*/uml/core/javahelp/org/netbeans/modules/uml/docs/basics/Attic/diagram_types_class.html?rev=1.1.2.2
* Class. If the class type is abstract, the class name is displayed in italics.
* Attributes. If an attribute is static (scope = class), the attribute name is underlined. If the attribute scope equals instance, the attribute name is not underlined.
* Operations. If the operation type is abstract, the operation name is displayed in italics. If the property of an operation is static, the operation name is not italicized.
Is the documentation here incomplete?

How to create OO Database from class diagrams?

If the Location of the datafiles is similar to that of source database then you can consider below steps
Create Oracle Service using oradim
set ORACLE_SID=NEWDB
oradim -new -sid NEWDB -intpwd passwordofthesys -startmode M
Connect to the RMAN
rman>rman target /
restore spfile/pfile and control file from backup
rman>restore spfile to pfile '_localtion of the initNEWDB.ora_' from '_location of the SPFILE Backuppiece_';
rman>startup nomount pfile='localtion of the initNEWDB.ora';
rman>restore controlfile from 'file location of the controlfile Backuppiece';
rman>alter database mount;
Catalog the RMAN backuppiece of source database
rman>catalog backuppiece '_location of the rman backuppiece of source database_ ';
resotore & recover database
rman>restore database;
rman>recover database;
open the database with reset logs
rman>alter database open resetlogs;
rman>create spfile from pfile;
rman>shutdown immediate;
rman>startup;
==================
If you have access to source database then you can clone using below rman command:
+rman target _<source database>_ auxiliary _<new database>_+
rman>duplication target database to _<your new database name>_;
==========
If the location of the datafiles and logfiles are different from source database then you need to add db_file_name_convert and log_file_name_convert to the pfile before starting the recovery process.

Can anyone tell me the class diagrams of a simple java notepad

hi,
Can anyone tell me the class diagrams of a simple java notepad.
i'm a very beginner in UML.
thanks in advance.

Don't worry too much about that. Figure out what it needs to do. Then grab JUnit and start writing tests & code.
On xprogramming.com there is a series of articles developing a notepad type app in C#. That might be of some help.

BC4J Audit Users Sample - How to use in a Class Diagram

I downloaded/reviewed the BC4J sample for auditing users, and am trying to incorporate it into a Class Diagram,
so I can explicitly show that my 'Entity' extends EntityAudit. When I create an 'EntityAuditImpl' Entity Object in the Class
Modeller, and then try to indicate that my 'Entity' extends EntityAuditImpl, I get a null pointer exception when applying the change.
Help! What is the proper way to express the relationship is a Class Diagram?

Randy,
It sounds as though you're trying to model the type of relationship where one entity object extends another one - which
in this case isn't the right relationship. In this case only the Java classes are being extended. So if your new EO is
called MyEO:
EntityAuditImpl extends EntityImpl
MyEOImpl extends EntityAuditImpl
One way to model this relationship:
1. Add a new entity object (MyEO) to your UML diagram
2. On the diagram, double-click MyEO to edit your entity object
3. In the entity object editor, select the Java page then click Extends...
4. In the Base Classes dialog, click Browse... to the right of the Row field, and navigate to EntityAuditImpl
5. Click OK, OK, OK to dismiss all of the dialogs.
If you take a look at MyEOImpl.java you'll see that the class extends EntityAuditImpl.
6. On the diagram, right-click MyEO and select Show Implementation Files. This adds MyEOImpl to the diagram.
7. Now, right-click MyEOImpl and select Show Related Elements. This adds EntityAuditImpl to the diagram, and shows
it as being the superclass of MyEOImpl.
Hope this helps
Blaise

Trouble with UML class diagram...

i understand tha in a UML class diagram: + thing : int would translate to java like this: public int thing;but what would + thing(int,int) translate into?

+ thing : intmeans that 'thing' is a public instance variable with type int.
+ thing(int, int) : intmeans that 'thing()' is a public instance method that takes 2 int arguments and returns an int.

Broken wire : Refnum Class diagram objet

Hi,
Many times on my applications. On several computers, different project and LabView version (2011 to 2014).
A "Refnum Class diagram objet" needs to be "updated" because its wire is broken.
The attached example shows a valid WaveformChart Refnum class reference which is suddenly and aleatory "broken" and needs to be reset. Otherwise the vi is broken ...
(In the example attached the Refnum "selected" by labview ar Control and "XControlTREE", the problem has no relation with its existence.)
Thank you
Best regards,
Ulysse

Hi Gerd,
I have had problems in the past with passing control references into subVIs. I had these problems because the strict control reference is often incompatible with a non-strict refnum control, or a strict refnum control of the wrong type. For example, if you have a multi-selection listbox, but you try to wire that control reference to a listbox reference associated with a scalar datatype (single-selection), you will get a wiring error.
The easiest solution for these problems is to right-click on the control reference and choose Create > Control. Then, copy this control into your subVI and use it as the subVI input. I think this will solve your class conflict problems.
If this doesn't work right, let me know and we can talk further...attachi
ng a sample LLB that demonstrates the problem would be helpful.

Hungarian Naming Contentions for UML Class Diagram

UML class diagram should be generic for all the available object oriented language and should not be language dependent. If we follow pure java naming conventions in UML class diagram, which make the UML class diagram Java language dependent not generic.
I am trying to combine Hungarian Naming Contentions with Java Naming Convention so variable name will follow x_y schema where x_ is according to Hungarian notation attached with class attribute, which is named according to java naming standard. This naming standard satisfies UML naming convention and will also help in java programming.
For an example,
i_userNumber Here 'i_' is a Hungarian notation representing type of variable attached with class attribute . This indicates that the attribute is an interger , which is named according to java naming standard.
Feedback Please

You're going to get a gozillion answers to this question, and all of them will be both right and wrong to some degree, so I will give you my thoroughly opinionated answer to go along with all the rest.
I am not a fan of Hungarian notation for one fairly fundamental reason. Java is a strongly typed language, thus it doesn't need indicators of type. By putting a type indicator on a variable you create potential problems when you change a data type. Won't happen? I am currently sweeping through a major portion of the application I'm working on changing data types for masses of variables because the database guys took a whim to change the data type in the database. If I were using Hungarian notation, not only would I have to change the type, the parameter type and return type for the accessor mutator methods, I'd also have to change the name, the name of the accessor and mutator methods, and anywhere that the variable is modified directly.
The name of a thing should speak for its self. It shouldn't need an indicator flag on the front to tell me what it is.
But you're talking about UML not Java code. The same thoughts apply. The name should speak for the thing it represents without the need for additional clarification.
Hungarian notation in my not so humble opinion adds complexity by requiring the development team to spend effort learning, understanding, thinking about, processing, manipulating, touching, dealing with what is essentially a thoroughly artificial naming scheme.
Just my thoughts on the subject. Your milage may of course vary wildly.

Understanding Sun Idemtity Manager using UML Class Diagrams

If you are a Sun IdM beginner and want to quickly and logically understand the relationships between various components in Sun IDM, then you should take a look at this:
http://objectsource.com/blogs/2010/02/understanding-sun-idm-using-uml/
You can also download all the UML diagrams from there.
For those of you who understand UML, you definitely know a UML class diagram is a picture worth 1000 words.
I never remembered all of these, so I used to carry a copy of these with me to custmer requirement and design discussions.
Whenever customer asked details that I could not recall or was not sure, I'd pull these out as a cheatsheet to confirm and further elaborate on the design approach for the Sun IdM feature implementation.
NOTE: I am the author of that blog as well. A little background on this post -
I wrote the blog post a few months ago and totally forgot about it.
A few days back, I installed wordpress site stats on my blog and I was amazed to see how many people look for Google terms "Understanding Sun IdM" and end up at my blog post.
I thought - "Hey If it was so useful to these people, then I believe it will be useful for many more" (especially developers from Java background that have turned to Sun IdM professionals)
Hence the post here.
A few years back, I started using Sun IdM and was absolutely unsure where to start and what relationships exist between various components. I painfully started to understand them by going through the admin console and started drawing out these diagrams. They were sitting in my vault, but I set them free a few months back.
Had I known what I know now, I would have released it much earlier.

playAgain() : bool
askBet() : int
Payout(amt: void) : void
takeBet(amt:void) : boolThese are methods of the "Game" class, and what is inside parentheses are called parameters.
"void" and "bool" are return types.
public boolean playAgain()
    }In this code you have specified boolean as a return type, so you need to return a value of type bool.
As for the void part, you don't need to return anything.
Code should look like:
public boolean playAgain()
         return true; //Or return false
public void Payout ()
         int amt;
    }You need to get :int amt" in the parameters, and since its voide nothing needs to be returned.
public void Payout (int amt)
    }
