| The Turbine processing pipeline is modelled after the pipeline found |
| in Tomcat 4.0.1 (Catalina), and after the module architecture found |
| in Apache httpd. It is extensionable both laterally and |
| vertically via Valve additions and default Valve implementations |
| (respectively). Even the semantics of the default Turbine |
| Pipeline (ClassicPipeline) can be changed by replacing or extending |
| the implementation with a custom one. |
| </p> |
| |
| <p> |
| As with Catalina, Turbine's Pipeline and Valve configuration is |
| setup via XML: |
| |
| <blockquote><code><pre> |
| |
| <pipeline> |
| <class>org.apache.turbine.pipeline.ClassicPipeline</class> |
| <valves> |
| <valve> |
| <class>org.apache.turbine.pipeline.Valve1</class> |
| </valve> |
| <valve> |
| <class>org.apache.turbine.pipeline.Valve2</class> |
| </valve> |
| <valve> |
| <class>org.apache.turbine.pipeline.Valve3</class> |
| </valve> |
| </valves> |
| </pipeline> |
| |
| </pre></code></blockquote> |
