Enclosing class:

WordCount

public static class WordCount.CountWords
extends <any>

A PTransform that converts a PCollection containing lines of text into a PCollection of formatted word counts.

Concept #3: This is a custom composite transform that bundles two transforms (ParDo and Count) as a reusable PTransform subclass. Using composite transforms allows for easy reuse, modular testing, and an improved monitoring experience.
