javax.servlet Class ServletOutputStream

java.lang.Object
  extended by java.io.OutputStream
      extended by javax.servlet.ServletOutputStream
All Implemented Interfaces:
Closeable, Flushable
public abstract class ServletOutputStream
extends OutputStream

Extends: java.io.OutputStream

提供用于将二进制数据发送到客户端的输出流。ServletOutputStream 对象通常是通过 ServletResponse#getOutputStream 方法获取的。

这是 servlet 容器实现的一个抽象类。此类的子类必须实现 java.io.OutputStream.write(int) 方法。

See also javax.servlet.ServletResponse

英文文档：

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.
