Structural search question

Hi,
$instance$.error($parameter$);

instance variable has expression type constraint of 'org.log4j.Category'
within hierarchy
parameter has expression type constraint of 'java.lang.Exception' within
hierarchy

Hi all,

I'm trying to find instances of bad usages of logging in our code, for example: log.error(exception). This seems like a good application for structural search, but for the life of me I can't figure it out. I need to do something like:

<variable of type extending org.log4j.Category>.error(<variable extending java.lang.Exception>)

Is this possible? For bonus points, can the same search find calls to debug, info, warn and fatal at the same time? Obviously that's just laziness though :)

As an aside, this seems like a good candidate for an inspection (log parameter calls default toString of exception type?)

Cheers,
Colin

That's great, thanks very much, Maxim.

I seem to recall seeing a plan a while ago to allow user-defined inspections using the structural search - did anything ever come of that?

Take a look at the "Structural Search Inspection"

I love being amazed from time to time :)
