OOP always talks about object (mutable or immutable) in terms of polymorphism, encapsulation and inheritance. Components library misses only inheritance, which, obviously, the "killer feature" in OOP. So we could say that Components library that take good ideas from OOP.
If you want call something on load of module, make call to this something explicit, ie: wrap it into a function and run on your system component start explicitly. This approach will give more flexibility and control on your state. 2015-06-18 13:08 GMT+03:00 Xiangtao Zhou <tao...@gmail.com>: > oop means object oriented programming, which doesn't mean mutable. record > is oop and immutable. when you use java, you can asume everthing is > immutable. > > if i use dynamic to implement the object, i can test it with "binding"; > others i can test with "with-redefs". so it works, except side effects. > > On Thursday, June 18, 2015 at 5:21:46 PM UTC+8, Atamert Ölçgen wrote: >> >> How is stuartsierra/component OOP when it is building an immutable object >> graph?
