code assistant / imports / documentation [message #47480]

Hi all

I'm new to eclipse. So far I've been using JBuilder for years.

Is there a way to tell the code assistant (popup with methods) to mark
deprecated methods?
A compiler warning tells me that one of the methods I'm trying to use is
deprected. In JBuilder I had a context menu that allowed me to immediately
open the JavaDoc documentation for the particular class (look up deprecation
hint). How do I do that with eclipse?
Do you know of a plugin that converts
import java.util.List;
import java.util.DateFormat;
style import statements to
import java.util.*;
?

Thanks for your help
Marcel

Would you like an unorganize imports option? ;)

Thanks for the reply. You didn't really answer my questions, though... ;-)

I don't wanna get rid of the deprecated warning - I want to improve my cody
by replacing the deprected method. eclipse is supposed to help me find the
right method.

I know that option. It's not about beeing organized/sorted or not. I want to
have as little import statements as possible. This can be achieved through
massive use of .* imports.

Well, if you use Ctrl+Space for auto completion, deprecated methods have
a yellow warning sign by them. If you then highlight the method in your
code and press F1, you can select "Javadoc for <method>" to see the javadoc.

"massive use of .* imports" is generally considered a poor practice by
most programmers (see section titled "Import on demand is pure,
unadulterated EVIL" at http://www.javadude.com/tools/importifier/ for
some reasons), so if you want that functionality, you will probably have
to write the plugin yourself.

Deprecated methods are marked with an exclamation mark icon in the Code
Assist popup.

Click on the class name and press Shift-F2 (Open External Javadoc).

Window > Preferences > Java > Organize Imports > "Number of imports
needed for .*".

Hope this helps,

why would you do that?

first you don't have to be bothered by the imports
because you can use the outline of eclipse that shields
the imports very nicely.

second * imports are very bad things.
You can make code with it that suddenly don't compile anymore
when upgrading to a newer JDK, this should be avoided.

Because I hate list of dozens of import statements!

That sounds real nice! How can I set this up?

Yeah, I'm fully aware of that!

I see. So you want a refactoring for replacing deprecated methods. And you'd
like obvious candidates to be offered as replacement suggestions or happen
automatically or something along those lines. Enter a bug report with an
enhancement request.

Using the Outliner to navigate your source will
make you 'jump' over import statements. There is
also a button in the toolbar which let you 'show the
source of the selected element only' (Tooltip).
So using the outliner makes you 'ignore/hide' the
import part (Its still there but you wont see it that
often).

Currently there is no way to colapse the import
part of a source, but as far as I learned, this is
part of the feature list of Eclipse 3.0 currently in
development.

Hope it was understandable ;)

How should that work? Replacements are often poorly documented.
But sth. like a migration tool with replace all calls of method abc()
for type XYZ with a call efg(), or similar, could be helpful in those
situations.

Agreed, it might be a dubious enhancement. But I can imagine something like
a migration tool which could take advantage of the new refactoring
particpants story to do a refactor rename based on a set of migration rules.
