Class ByteArrayInputStream

java.lang.Object
  jcontrol.io.InputStream
      jcontrol.io.ByteArrayInputStream

public class ByteArrayInputStream
extends InputStream

The ByteArrayOutputStream allows to access a byte array as an InputStream. An internal read pointer is increased on read accesses.

Field Summary

protected byte[]	m_array Underlying byte array.
protected int	m_readPos Internal read pointer.

Constructor Summary

ByteArrayInputStream(byte[] array)
Creates a new ByteArrayInputStream for the specified byte array.

Method Summary

int	available() Returns the number of bytes immediately available for reading from this stream.
void	close() Has no effect on the ByteArrayInputStream.
void	mark(int readlimit) Currently not supported.
boolean	markSupported() Currently not supported.
int	read() Reads a single byte from the stream.
void	read(byte[] b, int start, int length) Reads an array of bytes from the stream.
void	reset() Currently not supported.
void	skip(int length) Skips data from the stream.
