org.apache.tapestry.ioc.services.ClassFab.addMethod()
Adds a method. The method is a public instance method. @return a method fabricator, used to add catch handlers. @param modifiers Modifiers for the method (see {@link java.lang.reflect.Modifier}). @param signature defines the name, return type, parameters and exceptions thrown @param body The body of the method. @throws RuntimeException if a method with that signature has already been added, or if there is a Javassist compilation error
