| <h2>Usage Example</h2> |
| <p> |
| This processor routes FlowFiles based on their attributes |
| using the NiFi Expression Language. Users add properties with |
| valid NiFi Expression Language Expressions as the values. Each Expression must |
| return a value of type Boolean (true or false). |
| </p> |
| <p> |
| Example: The goal is to route all files with filenames that start with ABC down a certain path. |
| Add a property with the following name and value: |
| </p> |
| <ul> |
| <li><strong>property name</strong>: ABC |
| </li> |
| <li><strong>property value</strong>: ${filename:startsWith('ABC')} |
| </li> |
| </ul> |
| <p> |
| In this example, all files with filenames that start with ABC will follow the ABC relationship. |
