Examples of javassist.ClassPool.makeClass()

javassist.ClassPool.makeClass()
Creates a new class (or interface) from the given class file. If there already exists a class with the same name, the new class overwrites that previous class.
This method is used for creating a CtClass object directly from a class file. The qualified class name is obtained from the class file; you do not have to explicitly give the name. @param classfile class file. @throws RuntimeException if there is a frozen class with thethe same name. @see #makeClassIfNew(InputStream) @see javassist.ByteArrayClassPath
