Propagate parameters: neat!

Andrei

>

Got to use this for the first time, and I love it.

How does it work? Could you give a trivial example.
I tried many ways of introducing parameters in methods, but didn't see
anything propagate, while I needed it.

Hello Alain,

On the change method signature refactoring dialog you'll see two buttons
(close to the top rigth corner): one for exceptions, and another one for
parameter propagations.

If you add a new parameter (for instance) and choose to propagate the parameter,
you'll be presented with another dialog that shows the call tree, with options
to refactor the caller methods as well (there are check-boxes so you can
specify the ones you want to propagate the parameter for).

HTH,
Andrei

Oh, and this is only for the latest build, 3229.

Andrei,


Thanks.


When you've been using a tool for years, your eyes and fingers work
automatically, and you don't read those complex dialog as a newbie would.
That's why a little explanation/example would be welcome, when they
introduce a new feature, but that's another story.
And I rarely use "Change Method Signature" to add or remove parameters,
as intentions are available.

I've just posted 2 related requests:

- Propagate parameters deletion
http://www.jetbrains.net/jira/browse/IDEA-622

- Propagate parameters: make it work with "Introduce Parameter"
http://www.jetbrains.net/jira/browse/IDEA-621

Alain,
I knew it would be you who'll post these requests:-)

There is only one way to read this: you were thinking about it, but you
also were too lazy to do it yourself.
;)

And some people find the EAP is useless!!

Not me:-)
Though, as I'm indeed as lazy as you've guessed, I think that sometimes
being lazy is not a bad thing at all:)
Seriously, I don't quite understand how the propagation of parameter
deletion should work.

No I'd read it as they know it's needed, and they know it's going to be
asked for, and they know their feature was complete enough to toss out
there to get some feedback while they add more in the next round. :)

We do? No one told me! I'm going home. Cya!

You are in St. Peterburg? I though you were sitting in Praha?

Hello Thomas,

And why would that be a problem? I'm feeling like taking a day off myself,
just to support them. ;)

Hello Alain,

And I rarely use "Change Method Signature" to add or remove
parameters,
as intentions are available.

But doesn't the intention bring up the change method signature dialog anyway?
Or is it another way of using it (while still taking care of all the references)?

No it doesn't. It's fast, but the drawback is that you can't choose
where to place the new parameter: it's added at the end
=> sooner or later, you'll need to call "Change Method Signature" to
reorder the parameters.

Oh, I see, you're talking about the case when adding a parameter from within
a method's body. I don't like that one, since it doesn't update the references
and I have to hunt down all the compile errors after that.

But the intention that pops up when adding a parameter in a method invocation
does bring up the change method signature dialog, so I tend to use it more
often.
