Class ContentLengthInputStream

java.lang.Object
  java.io.InputStream
      org.w3c.www.http.ContentLengthInputStream

All Implemented Interfaces:

java.io.Closeable

public class ContentLengthInputStream
extends java.io.InputStream

The content length input stream is used internally to return entity bodies.

Field Summary

protected java.io.InputStream	in The original input stream.
protected int	length The number of bytes readable from the above stream.
protected int	marklength The place of a single pending mark.
protected HttpStreamObserver	observer The stream observer, if any.

Constructor Summary

ContentLengthInputStream(HttpStreamObserver observer, java.io.InputStream in, int length)

ContentLengthInputStream(java.io.InputStream in, int length)
Builds a new content-length input stream.

Method Summary

int	available()
void	close()
void	finalize() Make sure the stream is ultimately closed !
void	mark(int readlimit)
boolean	markSupported() do we support mark() ? it depends on the underlying InputStream
int	read()
int	read(byte[] b, int off, int len)
void	reset()
long	skip(long n)

Constructor Detail

ContentLengthInputStream

public ContentLengthInputStream(java.io.InputStream in,
                                int length)

Builds a new content-length input stream. This stream acts as a normal stream except that it will return an end of file, after count bytes have been delivered.
