Class HttpOutput

java.lang.Object

java.io.OutputStream

javax.servlet.ServletOutputStream

org.eclipse.jetty.server.HttpOutput

All Implemented Interfaces:

Closeable, Flushable, AutoCloseable, Runnable

Direct Known Subclasses:

GzipHttpOutput

public class HttpOutput
extends ServletOutputStream
implements Runnable

HttpOutput implements ServletOutputStream as required by the Servlet specification.

HttpOutput buffers content written by the application until a further write will overflow the buffer, at which point it triggers a commit of the response.

HttpOutput can be closed and reopened, to allow requests included via RequestDispatcher.include(ServletRequest, ServletResponse) to close the stream, to be reopened after the inclusion ends.
