public void setImplicitClassNames(Map<String,String> implicitClassNames)

Can modify the class name request from javassist. Used to improve performance to skip pointless name checks.

acceptPathAsClass

public boolean acceptPathAsClass(String classname)

Says to javassist if the path can even be a class name. Used to improve performance to skip pointless name checks.

acceptPathAsPrimitive

public boolean acceptPathAsPrimitive(String classname)

process

public abstract void process(org.zeroturnaround.bundled.javassist.ClassPool cp,
                             ClassLoader cl,
                             org.zeroturnaround.bundled.javassist.CtClass ctClass)
                      throws Exception
