ServletOutputStream (Apache Tomcat 7.0.109 API Documentation)

java.lang.Object
- java.io.OutputStream
- - javax.servlet.ServletOutputStream

All Implemented Interfaces:

Closeable, Flushable, AutoCloseable

Direct Known Subclasses:

AbstractServletOutputStream, ByteArrayServletOutputStream, CoyoteOutputStream, ExpiresFilter.XServletOutputStream
```
public abstract class ServletOutputStream
extends OutputStream
```
Provides an output stream for sending binary data to the client. A ServletOutputStream object is normally retrieved via the ServletResponse.getOutputStream() method.
This is an abstract class that the servlet container implements. Subclasses of this class must implement the java.io.OutputStream.write(int) method.
