Normal rectangle with a dotted rectangle in the top right corner, to represent the template parameter. Something like this:


               .......               
    ___________:  T  :
    |          :.....:
    |              |
    |  ClassName   |
    |              |
    |______________|




A more useful approach is to use a UML Classifier for the Template. This is a UML Element that represents an extension to the UML notation.  If your tool supports profiles create the Classifier within one.   Define the Classifier for the Template, and include the properties and methods from the template, then instead of using the standard class notation, use the Classifier you have created for each Class that uses the template.  This would be correct usage of the UML for Templates.

I&#39;ve recently had to switch encoding of webapp I&#39;m working on from `ISO-xx` to `utf8`. Everything went smooth, except properties files. I added `-Dfile.encoding=UTF-8` in `eclipse.ini` and normal files work fine. Properties however show some strange behaviour.

If I copy `utf8` encoded properties from Notepad++ and paste them in Eclipse, they show and work fine. When I reopen properties file, I see some Unicode characters instead of proper ones, like:

    Zur\u00EF\u00BF\u00BDck instead of Zur&#252;ck

but app still works fine.
If I start to edit properties, add some special characters and save, they display correctly, however they don&#39;t work and all previously working special characters don&#39;t work any more. 

When I compare local version with CVS I can see special characters correctly on remote file and after update I&#39;m at start again: app works, but Eclipse displays Unicode chars.

I tried changing file encoding by right clicking it and selecting „Other: UTF8” but it didn&#39;t help. It also said: „determined from content: ISO-8859-1”

I&#39;m using Java 6 and Jboss Developer based on Eclipse 3.3

I can live with it by editing properties in Notepad++ and pasting them in Eclipse, but I would be grateful if someone could help me with fixing this in Eclipse.

Python&#39;s getattr() method is useful when you don&#39;t know the name of a certain attribute in advance.

This functionality would also come in handy in templates, but I&#39;ve never figured out a way to do it. Is there a built-in tag or non-built-in tag that can perform dynamic attribute lookups?

In Java you can define generic class that accept only types that extends class of your choice, eg:

    public class ObservableList&lt;T extends List&gt; {
      ...
    }

This is done using &quot;extends&quot; keyword.

Is there some simple equivalent to this keyword in C++?

I&#39;ve been trying to understand what&#39;s the optimal way to do [Ajax][1] in [Django][2]. By reading stuff here and there I gathered that the common process is: 

1. formulate your Ajax call using some [JavaScript][3] library (e.g., [jQuery][4]), set up a URL pattern in Django that catches the call and passes it to a view function

2. in the [Python][5] view function retrieve the objects you are interested in and send them back to the client in JSON format or similar (by using the built in serializer module, or [simplejson][6])

3. define a callback function in JavaScript that receives the JSON data and parses them, so to  create whatever HTML is needed to be displayed. Finally, the JavaScript script puts the HTML  wherever it should stay.

Now, what I still don&#39;t get is *how are Django templates related to all of this?* Apparently, we&#39;re not making use of the power of templates at all. 
Ideally, I thought it&#39;d be nice to pass back a JSON object and a template name, so that the data could be iterated over and an HTML block is created. But maybe I&#39;m totally wrong here...

The only resource I found that goes in this direction is [this snippet (769)][7] but I haven&#39;t tried it yet. 
Obviously, what&#39;s going to happen in this case is that all the resulting HTML is created on the server side, then passed to the client. The JavaScript-callback function only has to display it in the right place.

Does this cause performance problems? If not, even without using the snippet above, why not formatting the HTML directly in the backend using Python instead of the front-end?

Many thanks! 

**UPDATE: please use [snippet 942][8] because it is an enhanced version of the one above!** I found that the inheritance support works much better this way..

Rendering JSON objects using a Django template after an Ajax call

I have the following template String: `&quot;Hello [Name] Please find attached [Invoice Number] which is due on [Due Date]&quot;`.

I also have String variables for name, invoice number and due date - what&#39;s the best way to replace the tokens in the template with the variables?  

(Note that if a variable happens to contain a token it should NOT be replaced).

----------

**EDIT**

With thanks to @laginimaineb and @alan-moore, **here&#39;s my solution:**

    public static String replaceTokens(String text, 
                                       Map&lt;String, String&gt; replacements) {
        Pattern pattern = Pattern.compile(&quot;\\[(.+?)\\]&quot;);
        Matcher matcher = pattern.matcher(text);
        StringBuffer buffer = new StringBuffer();

        while (matcher.find()) {
            String replacement = replacements.get(matcher.group(1));
            if (replacement != null) {
                // matcher.appendReplacement(buffer, replacement);
                // see comment 
                matcher.appendReplacement(buffer, &quot;&quot;);
                buffer.append(replacement);
            }
        }
        matcher.appendTail(buffer);
        return buffer.toString();
    }

How to replace a set of tokens in a Java String?

I know it&#39;s possible to make a template function:

    template&lt;typename T&gt;
    void DoSomeThing(T x){}

and it&#39;s possible to make a template class:

    template&lt;typename T&gt;
    class Object
    {
    public:
        int x;
    };

but is it possible to make a class not within a template, and then make a function in that class a template? Ie:

    //I have no idea if this is right, this is just how I think it would look
    class Object
    {
    public:
        template&lt;class T&gt;
        void DoX(){}
    };

or something to the extent, where the class is not part of a template, but the function is?

In a UML class diagram, what is the difference between an association relationship and a dependency relationship?

From what I know, an association is a stronger relationship than a dependency, but I&#39;m not sure how it is stronger.

Any example would be more than welcome :)

How can you clearly illustrate multiple threads of execution in a sequence diagram or similar diagram?  

I haven&#39;t been able to find any clear examples.  All diagrams I see are used to illustrate a single thread.

---

**Update**: The accepted answer was the best example I saw but it does leave a fair bit to be desired.  I ended up illustrating the threads in separate sequence diagrams.  I&#39;m not sure if the sequence diagram necessarily works for multiple threads.

Please suggest tools for creating Class Diagrams with the following criteria:

 - It should be platform-independent because I use Linux and the file is expected to be edited by other members of the team using Windows/Mac
 - Free, because there no such free tool, we should create one
 - It would also be nice if you can include a screenshot of the class diagram produced, just to make sure that the tool is actually used for creating Class Diagrams and not just any other types of diagrams

Also, please only suggest the tools that you&#39;ve actually used.

UPDATE: Please DO NOT include those UML Diagram tools that cannot create Class Diagrams.
