I'm very new to design patterns and am having trouble with the difference between fluent interfaces and the Builder pattern. Therefore, we are going to use a Recursive Generics approach to enable the default behavior of our fluent interfaces. 3.1. The fluent builder pattern is similar to any fluent API call, but this is used to build the object. With a properly-written fluent interface, you can enforce “rules of grammar”, and make it so certain methods cannot be called, until all the required setup methods have been called. An idea which is quite similar to fluent interfaces is the Builder pattern, which works almost the same as the setters above, but that is a topic for another article. Welcome to the concept of “Fluent interfaces”. There are three steps I use to create a fluent interface. Let's compare two implementations evaluating several points. This is an over-simplified implementation and lacks some properties of a fluent interface. Discussion. The API is primarily designed to be readable and to flow between methods. Method chaining is calling a method of an object that return the same type of the object multiple times. I cannot understand the use of a Director in the Builder pattern. This is an example of the Method chaining design pattern in Haxe.. Fluent API is a nice thing, but I would go a different way in your case. Same technique that the builder pattern to build an Domain Specific Language in declarative way. Builder Design Pattern and Fluent Builder; Fluent Builder Interface With Recursive Generics (Current article) Upload image. Method chaining / Fluent interface. Motive 3. Steps to build a fluent interface. I understand the concept of fluent interfaces. This pattern is known since 2005 and the founders are Eric Evans and Martin Fowler as you can read in his post and it’s very likely you already used it. Chris already discussed a few design pattern like the Null Object Pattern and the Singleton Pattern and today its my pleasure to introduce you to the Fluent Interface Pattern. Comparing Builder Pattern and Fluent Interface. Building a car draws me more towards the Builder pattern.That way you would hide a car being composed in a factory (not the factory method pattern) which accepts commands like you have now, but do not accept questions. But the builder pattern is a little confusing. Reading time: 2 minutes. Can I use the Builder pattern and Fluent Interface together? But it serves well for our comparison needs. The Fluent builder is a small variation of the Builder design pattern, which allows us to chain our builder calls towards different actions. “Fluent interfaces simplify your object consumption code by making your code more simple, readable and discoverable.” So if our component consumers can write object invocation code in simple English sentence like below , … Maybe with Linq in .Net or JBehave in Java. In software engineering, a fluent interface (as first coined by Eric Evans and Martin Fowler) is an implementation of an object-oriented API that aims to provide the most readable code. But if one Fluent Builder inherits from another one, well, we are going to have a problem with chaining actions. Note that fluent interfaces generally act as a facade over a set of classes. Spark script uses heavily this concept to process data. Subscribe.
