[jboss-user] [Javassist] - Method Content Comparison

David Jakes [http://community.jboss.org/people/chicken_bones] created the discussion "Method Content Comparison" To view the discussion, visit: http://community.jboss.org/message/641879#641879 -------------------------------------------------------------- I am trying to make a compatibility class loader. General scenario. People edit the source file, change the contents of a few methods and add a few fields and then recompile the class. I then compare the original class and the changed class with javassist. I need to detect when the methods haven't been changed. I tried measuring the length of the code attribute but that fails when the change is a single field access redirection for example. I also tried comparing the contents of the arrays but that didn't work as various bytes at seemingly coordinated locations in the attribute have different values. Due to the fact I don't actually understand how to read the bytecode I'm unable to work out a solution. If someone could help point me in the right direction or give me a sample of code that could analyse this for me that would be great. Thankyou for your time. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/641879#641879] Start a new discussion in Javassist at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
