Analysis of methods
Hi all,
I need to analyse a class (dynamically during classloading or runtime,
or statically with .java or .class) to identify, for all methods of this
class, if a method read or update a class field. How to achieve that?
Is there some projects that already achieve that? What are my options?
Thanks for your help
Jean

I've done this as part of the JAC project: http://jac.objectweb.org/
You may have a look at the fillRTTI method of WrappeeTranslator_BCEL
(see
http://cvs.forge.objectweb.org/cgi-bin/viewcvs.cgi/jac/jac/src/org/objectweb/jac/core/translators/WrappeeTranslator_BCEL.java)

Laurent

Hi,
I am working on something which does need the same feature. I did'nt succeed
yet, but it seems as if one has to seek for getfield or putfield commands.
That's how they are called by Class2HTML.
Regards,
Mark

The last three links on
http://cvs.apache.org/~pietsch/
point to a Java file which implements a BCEL 5.0 based analyzer and
associated files. The analyzer tries to determine whether fields
and methods are only accessed by the class itself (allows private
access), subclasses (protected) or other classes, in order to
determine if the declared access class is to broad.
Maybe you can pick something from this. The BCEL 5.1 examples
have similar, possibly simpler code.
