Breaking down the Builder pattern

As part of the Creational family of design patterns, the Builder pattern focuses on creating different representations of a complex object while delegating the customized building instructions to concrete builder classes. You’ll find this pattern is most useful in scenarios where:

• You need to separate the construction of complex objects from their representations.
• You want to build different objects using the same construction process.
• Finer control of each step of the construction process is necessary.
• You want to delegate creating the object to an encapsulated builder instead of directly creating them in the client.

The Builder pattern example that’s familiar to most people is the assembly line – in this case, a car factory. When your favorite (or rival) car manufacturer sets up a factory, they can specify common production steps that all their different makes and models have to go through...
