Class ServletInputStream

java.lang.Object
  java.io.InputStream
      javax.servlet.ServletInputStream
All Implemented Interfaces:
java.io.Closeable
public abstract class ServletInputStream
extends java.io.InputStream

Provides an input stream for reading binary data from a client request, including an efficient 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.

Method Detail

readLine

public int readLine(byte[] b,
                    int off,
                    int len)
             throws java.io.IOException
Reads the input stream, one line at a time. Starting at an offset, reads bytes into an array, until it reads a certain number of bytes or reaches a newline character, which it reads into the array as well.

This method returns -1 if it reaches the end of the input stream before reading the maximum number of bytes.

Parameters:
b - an array of bytes into which data is read
off - an integer specifying the character at which this method begins reading
len - an integer specifying the maximum number of bytes to read
Returns:
an integer specifying the actual number of bytes read, or -1 if the end of the stream is reached
Throws:
java.io.IOException - if an input or output exception has occurred
