public class ResponseWriter

extends java.io.PrintWriter

Wrapper around the standard java.io.PrintWriter that keeps track of whether or not any characters have ever been written (even if they are still buffered inside the PrintWriter or any other Writer that it uses above the underlying TCP/IP socket). This is required by the semantics of several calls on ServletResponse, which are required to throw an IllegalStateException if output has ever been written.
