@Casper Bang:

1) I never said Bloch invented the pattern. The reason I refer to it as Bloch’s Builder pattern is because his pattern isn’t exactly the same as the GoF pattern, and thus needs to be distinguished.

2) I disagree with this point. Although property initializers make unnecessary some types of Builders, there are still things they can’t do. For example, you cannot create immutable objects with property initializers, but you can with a Builder.

3) The Builder patterns in this article, as well as Bloch’s Java Builder, support chaining.

1) Bloch did not invent that pattern. It’s part of a whole arcade of patterns classified as “creational” and immortalized in the seminal book by the GoF in 87′.

2) C# has property initializers, making the builder pattern somewhat unnecessary.

3) The builder pattern is defined by method chaining, surely nothing stands in the way of using setCalories(…).build() in C#?

@Vili: Which approach are you talking about?

Hi,

I think you could write your public properties with just set; and you would have a write-only property
