public class LocalNutchInputComponent

extends com.dawidweiss.carrot.core.local.LocalInputComponentBase

A local input component that ignores the query passed from the controller and instead looks for data stored in the request context. This enables us to reuse the same physical component implementation for data that has already been acquired from Nutch.
