Class ReadLimitInputStream

java.lang.Object
  java.io.InputStream
      ikrs.io.BytePositionInputStream
          ikrs.io.ReadLimitInputStream

All Implemented Interfaces:

java.io.Closeable

public class ReadLimitInputStream
extends BytePositionInputStream

This input stream is an extension of the BytePositionInputStream. It stores a read limit (long) which, when reached, causes EOI.

Constructor Summary

ReadLimitInputStream(java.io.InputStream in, long readLimit)

Method Summary

int	available()
void	close()
protected long	getMaxAvailable()
void	mark(int readlimit) The mark-method is a bit tricky! This implementation does NOT support marks and throws an IOException if called.
boolean	markSupported()
int	read()
int	read(byte[] b)
int	read(byte[] b, int off, int len)
void	reset()
long	skip(long n)
java.lang.String	toString()
