Package org.eclipse.jetty.server

Class HttpInput

java.lang.Object

java.io.InputStream

javax.servlet.ServletInputStream

org.eclipse.jetty.server.HttpInput

All Implemented Interfaces:

Closeable, AutoCloseable, Runnable

public class HttpInput
extends javax.servlet.ServletInputStream
implements Runnable

While this class is-a Runnable, it should never be dispatched in it's own thread. It is a runnable only so that the calling thread can use ContextHandler.handle(Runnable) to setup classloaders etc.
