Does it make sense to have a feature request to warn developer about unused
public method in a class?
In the compiler option, it can warn users about unused private methods. I am
wonder if it make sense to have a feature to warn about unused public
method. I think unused public method is more tricky than unused private
method.

What about a framework?
There are many unused methods. What about abstract classes? Seems not
very useful | hard to implement.

It's quite hard to determine what is really not used if it's not
private. Imagine, for example, that you have some other project calling
a public method. If you close this project, the public method appears
not to be called, which is of course not true.

Best regards,

Jesper

Go get the plugin JQuery
(http://www.cs.ubc.ca/labs/spl/projects/jquery/index.htm)
It will do this and much more. It's a complete java source query engine so
you can define your own queries and add them to JQuery's menu (even on a
per-project basis).
The tutorial actually has the query close to what you are looking for
"Methods NOT called from elsewhere" which will show you all methods in a
package not called. It could easily be expanded to only show public
methods as well as well as make it applicable per class.
It's an amazing piece of work.
However, as the others said, this functionality is limited to a project at
a time probably for those reasons mentioned.

Yes. RefactorIt does this.

This is the tutorial at:

http://www.cs.ubc.ca/labs/spl/projects/jquery/tutorial.htm

....?

I can't seem to see the example you are referring to.

It /seems/ to list methods that are called - not those which are not.

Yea, looks like the tutorial page is incomplete. If you look in the
actualy file for the tutorial.rub in the distro at
%PATH%\plugins\ca.ubc.jquery\rules you'll see a few rules defined not
mentioned on the page ("Methods called from elsewhere" and "Methods NOT
called from elsewhere".
The rule as defined will only show up for package but if you change the
":- package(?P)." to ":- package(?X) ; class(?X)." (; is "or" in prolog)
You should also be able to modify the rule with "modifier(?M,public)" so
it only shows public methods not called from elsewhere.

Also, I got an email back from one of the authors and he says the new
version will be able to do queries on *working sets*!

Take care,

John

I can see the rule - in the "tutorial.rub" file there.

If I try and load that file from the menu I get errors.

Also, my attempts to execute the query have been thwarted by "paste"
being disabled in the query textbox.

The only way I can enter queries seems to be by typing them in by hand :-(

This tool may offer potentially interesting functionality.

However, currently the user interface doesn't seem to conveniently
expose very much of it :-|
