Newbie: Use Bcel to analysis class file
Hi,
I am new to bcel.
Can you please tell me if I can use BCEL to analysis class file, e.g.
I would like to find out how much (in term of the size in bytes)of the
class file is Constant pool, Fields, Methods?
Thank you.

This *might* be easier to do with ASM. You could wrap the input stream
and check at each event where you are at ...but this only works if ASM
does not buffer the stream.
Someone asked a similar question on the ASM list. Maybe have a dig there.
cheers

Thanks for your help. I would like to analysis each class in the jar,
so it is easier for me if I can write a tool to do that.
Thank you.

BCEL wouldn't be able to tell you the size in bytes of various sections of
the class file using the api.
You could get a rough estimate i suppose, but if that is what you want, it
would probably be better just to
read the class file yourself.
