| <h2>FlatMapElements</h2> |
| <p> |
| The Beam SDKs provide language-specific ways to simplify how you provide your DoFn implementation. |
| </p> |
| <p> |
| FlatMapElements can be used to simplify a DoFn that maps an element to multiple elements (one to |
| many). |
| </p> |
| <p> |
| <b>Kata:</b> Implement a function that maps each input sentence into words tokenized by whitespace |
| (" ") using |
| <a href="https://beam.apache.org/releases/javadoc/current/org/apache/beam/sdk/transforms/FlatMapElements.html"> |
| FlatMapElements.into(...).via(...)</a>. |
