public abstract class ServletInputStream
extends java.io.InputStream
readLine method for reading data one line
 at a time. With some protocols, such as HTTP POST and PUT, a
 ServletInputStream object can be used to read data sent from the
 client.
 
 A ServletInputStream object is normally retrieved via the
 ServletRequest.getInputStream() method.
 
 This is an abstract class that a servlet container implements. Subclasses of
 this class must implement the java.io.InputStream.read() method.
