question: public static final < R > R dispatch ( Class clazz , Object instance , String method , Object [ ] args , Class [ ] types ) throws NoSuchMethodException { try { java . lang . reflect . Method m = clazz . getDeclaredMethod ( method , types ) ; m . setAccessible ( true ) ; return ( R ) m . invoke ( instance , args ) ; } catch ( NoSuchMethodException x ) { if ( clazz . getSuperclass ( ) != null ) return ( R ) dispatch ( clazz . getSuperclass ( ) , instance , method , args , types ) ; else throw x ; } catch ( Exception x ) { throw new RuntimeException ( x ) ; } }
target:  Dispatch `args` of `types` to `method` on `clazz` for `instance`. If `method` is static, `instance` should be null.
