However, i don’t want to copy the implement code into my extension. so, i have two options: 1. copy the duplicate code into my extension, It can be fast in this way, but the code is not beautiful. 2. call call_user_function(_ex) , it’s slower than the first option, but the code is more simple and beautiful than the first option.. cheers, Wei Dai
