Examples of javassist.CtClass.addField()

javassist.CtClass.addField()
Adds a field.
The CtField belonging to another CtClass cannot be directly added to this class. Only a field created for this class can be added. @see javassist.CtField#CtField(CtField,CtClass)

      CtField field = new CtField(
            joinpoint,

            genadvisor);
      field.setModifiers(Modifier.PUBLIC);
      genadvisor.addField(field);
