Intent

Allows processing of data in a series of stages by giving in an initial input and passing the processed output to be used by the next stages.

Applicability

Use the Pipeline pattern when you want to

• execute individual stages that yields a final value
• add readability to complex sequence of operations by providing a fluent builder as an interface
• improve testability of code since stages will most likely be doing a single thing, complying to the Single Responsibility Principle (SRP)

Typical Use Case

• implement stages and execute them in an ordered manner

Real world examples

• java.util.Stream
• Maven Build Lifecycle
• Functional Java
