Intent
Collection Pipeline introduces Function Composition and Collection Pipeline, two functional-style patterns that you can combine to iterate collections in your code. In functional programming, it's common to sequence complex operations through a series of smaller modular functions or operations. The series is called a composition of functions, or a function composition. When a collection of data flows through a function composition, it becomes a collection pipeline. Function Composition and Collection Pipeline are two design patterns frequently used in functional-style programming.
Applicability
Use the Collection Pipeline pattern when
- When you want to perform a sequence of operations where one operation's collected output is fed into the next
- When you use a lot of statements in your code
- When you use a lot of loops in your code
