public class ResponseWriter
extends PrintWriter

Specialized PrintWriter for servlet Responses

An instance of ResponseWriter is the PrintWriter subclass returned by Response.getWriter(). It differs from the standard PrintWriter in that:

• It does not support autoflush
• The default Locale for format(String, Object...) is the locale obtained by ServletResponse.getLocale()
• If a write or print method is called while checkError() returns true, then a RuntimeIOException is thrown to stop needless iterations.
• The writer may be reopen to allow for recycling
