org.apache.catalina.Pipeline

Interface describing a collection of Valves that should be executed in sequence when the invoke() method is invoked. It is required that a Valve somewhere in the pipeline (usually the last one) must process the request and create the corresponding response, rather than trying to pass the request on.

There is generally a single Pipeline instance associated with each Container. The container's normal request processing functionality is generally encapsulated in a container-specific Valve, which should always be executed at the end of a pipeline. To facilitate this, the setBasic() method is provided to set the Valve instance that will always be executed last. Other Valves will be executed in the order that they were added, before the basic Valve is executed.
