      LimitedOutputStream

All Implemented Interfaces:

Closeable, Flushable

 class LimitedOutputStream
extends OutputStream

This class is useful only for testing the transmission speed of data by limiting the size of the output stream. Not to be used in production.

Field Summary

private int	limit The limit on the number of bytes
private OutputStream	realOut The output stream to receive the limited output
private int	total How many bytes have been output so far

Constructor Summary

LimitedOutputStream(OutputStream realOut, int limit)
Constructor.

Method Summary

void	close() Close the output stream
void	flush() Flush any pending data to the output stream
void	write(byte[] b) Write an array of bytes to the output stream
void	write(byte[] b, int off, int len) Write a subset of bytes to the stream
void	write(int b) Write a single byte to the stream
