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
