Builder Design Pattern Logo

Builder is a creational design pattern which aims on decoupling the construction logic of a complex object from its representation.


Sometimes an object construction can be complex, because of parameter validations, search of informations on files or database, or even for numerous parameters the object’s constructor is waiting to receive. If you mix up the logic creational logic along the class’s behaviour logic, you may lose the class’s cohesion and can make it difficult to reuse.

Builder design pattern comes to solve this problem, putting both creational and behavioural logic on it right places, by providing enough encapsulation for object’s construction, in such a way you can even develop any number of different implementations for a single builder.
