@globalincident6944 жыл бұрын
The thing is though, strategies aren't all good. They are useful when the equivalent hierarchy would result in people creating lots of subclasses of your class, and in those subclasses sharing lots of code between each other in a way that makes doing it as a hierarchy complicated. But in my experience that doesn't happen that often.

@@globalincident694 - In my opinion, the Liskov Substitution principle points out a flaw/limitation in OO languages, rather than a principle. In real world programming, your rarely get hierarchies/taxonomies that can obey LSP, yet remain useful. I like the concept of "adhoc polymorphism" in languages like Haskell. Model the hierarchies/taxonomies as best you can, but let the differences exist. The compiler will tell you when you go wrong.

@@planomustang1 I wouldn't say Liskov substitution is a flaw. It's present to an extent in Haskell too - if you are creating an instance of a class, the instance also needs to have the methods of the parent class. If you're having a problem with it, that usually means there's a flaw in your class structure - maybe that class shouldn't have that method - rather than a problem with liskov substitution.

@@globalincident694 No. Haskell allows adhoc polymorphism. In other words, you don't have to implement a parent's method, if it does not apply to the child. The compiler will only complain, if something tries apply the parent method to the child. Javac/C++ will complain at compile time, though there is no evidence the method is needed on the child. That is why LSP points to a problem, rather than a solution. OO models are too strict. Adhoc Polymorphism is a good thing. FYI, I learned about LSP in 1996.

The strategy pattern seems like a workaround for languages that don't have lambdas
@uumlau5 жыл бұрын
A lot of design patterns use abstract classes or interfaces to achieve what delegates/lambdas do. The classic Gang of Four book was published in 1995, so C++ was the standard of the time, and it didn't have delegates/lambdas yet, where the important part was to define the signature of the method. C++ could also use function pointers, but function pointers were just pointers and couldn't have explicit method signatures, hence the use of interfaces. It would be another decade or so before lambdas became common. So yeah, it's totally legit - and a lot lighter - to inject a lambda instead of a full blown class/interface hierarchy.
@marcpawl5 жыл бұрын
A lambda is an implementation of a one method interface. A lambda maps to a class with no name. You might want to check out c++ weekly which had a discussion on lambdas. Passing in a lambda is the ultimate strategy pattern example.
@Layarion4 жыл бұрын
@@uumlau could you explain to a c# noob, how lamba's replace interfaces or this pattern? to me a lambda just seems like a nice way to use something once and move on.
@uumlau4 жыл бұрын
@@Layarion Well, if a method takes an interface as an argument, a concrete instance of that interface can contain a method. The strategy pattern can be implemented by allowing any number of different concrete classes containing different methods (strategies). It is possible instead to take a Func or Action and supply different methods that way. In all cases, the method needs to have the same signature, but otherwise the particular method to be used can be specified at run time. Sometimes an Interface or Abstract class is more efficient, especially if you have a large family of methods with different signatures to specify for each case of the strategy. Usually, however, the need for a strategy pattern is a simple decision to replace a single method, not a family, in which case a delegate can be used (declared as a Func or Action), and then whatever lambda you send just needs to have the correct signature. I've used this in real life to implement business rules dynamically, where I have a lists of business rules that are declared as lambdas (which lets me edit/modify them individually as specifications change without rewriting code or decision trees), and I can just run a foreach of the appropriate list of rules against the state of the application. Notice how this not only allows for multiple families of rules, it is far more flexible than an Interface or Abstract class, where I would have to declare each new method in the Interface/class. Instead of declaring an extra method, I just add/remove from the list of lambdas, and the signatures of methods and business logic evaluation doesn't change. Only the specific lambdas change. Combine this with commenting each lambda with the English version of the requirement, and this makes for very readable code that even a novice can easily modify.

I think 27.31 really highlights the point of strategy pattern: instead of creating subclasses that implement a parent class; we instead create different implementations of methods/algorithms (these are called 'stategies'). These strategies can then be "assembled together" to create an object with the configuration that we want. Using such 'configurable' objects in place of subclasses means that we can conveniently reuse the strategies in a 'horizontal' way.
