22.6 The Class

java.io.ByteArrayInputStream

A

ByteArrayInputStream

 contains an internal buffer that contains bytes that

may be read from the stream. An internal counter keeps track of the next byte to

be supplied by the

read

 method. See also

StringBufferInputStream

 ( 22.7).

public class ByteArrayInputStream extends InputStream {

protected byte[] buf;

protected int pos;

protected int count;

public ByteArrayInputStream(byte[] buf);

public ByteArrayInputStream(byte[] buf,

int offset, int length);

public int read()

throws NullPointerException, IndexOutOfBoundsException;

public int read(byte[] b, int off, int len)

throws NullPointerException, IndexOutOfBoundsException;

public long skip(long n);

public int available();

public void reset();

}

22.6.1

protected byte[] buf;

An array of bytes that was provided by the creator of the stream. Elements

buf[0]

through

buf[count 1]

 are the only bytes that can ever be read from the stream;

element

buf[pos]

 is the next byte to be read.

22.6.2

protected int pos;

This value should always be nonnegative and not larger than the value of

count

.

The next byte to be read from this stream will be

buf[pos]

.

22.6.3

protected int count;

This value should always be nonnegative and not larger than the length of

buf

. It

is one greater than the position of the last byte within

buf

 that can ever be read

from this stream.
