Class ServletOutputStream

java.lang.Object

java.io.OutputStream

javax.servlet.ServletOutputStream

All Implemented Interfaces:

java.io.Closeable, java.io.Flushable, java.lang.AutoCloseable

Direct Known Subclasses:

ServletOutputStreamImpl

public abstract class ServletOutputStream
extends java.io.OutputStream

Servlets can use ServletOutputStream to write binary data to the response. ServletOutputStream provides several methods similar to the methods of PrintWriter.

Typically, servlets will use response.getOutputStream to get this object.

Note, the PrintWriter-like methods do not handle character encoding properly. If you need non-ascii character output, use getWriter().

Buffering of the output stream is controlled by the Response object.
