The Builder design pattern encapsulates the properties of an object and allows you to construct a representation of it.
This pattern lets you construct complex objects, with different properties even though they belong to the same class.
A typical object class contains attributes, constructors, and methods.
it’s possible for you to then use these builder classes to create different variations of the same object.
The product in this sample system is a pizza.
The builder interface will allow you to create each aspect of the pizza object separately.
It will then allow you to retrieve the entire pizza object.
Therefore, one pizza that a customer will order is cheese.
The CheesePizzaBuilder class implements the Builder interface and uses it to create a new cheese pizza.
This is one representation of the Pizza object.
It also does this in a way that is independent of the Pizza class.
Now every time the tool calls the CheesePizzaBuilder class it will create a new Pizza that has cheese topping.
The Director Class
The director class is a crucial aspect of the builder pattern.
The sole purpose of a concrete builder class is to create a specific object.
It achieves this by creating the different parts of an object separately.
However, the builder concrete classes are unaware of the algorithm.
None of the builder classes knows to build the dough before adding the topping.
This is the function of the director class.
The Director class uses the builder interface to make pizzas.
It is the keeper of the algorithm.
This is a crucial aspect of software engineering, as it aids in the development of secure applications.
Another advantage of this design pattern is its object construction approach.
It lets you create multistep processes, where each step is independent, which makes debugging easier.
