THE PACKAGE JAVA.IO

22.10.3

protected int pos = 0;

This value is always in the range

0

 through

count

. If it is less than

count

, then

buf[pos]

 is the next byte to be supplied as input; if it is equal to

count

, then the

next

read

 or

skip

 operation will require more bytes to be read from the contained

input stream.

22.10.4

protected int markpos =  1;

This value is always in the range

 1

 through

pos

. If there is no marked position in

the input stream, this field is

 1

. If there is a marked position in the input stream,

then

buf[markpos]

 is the first byte to be supplied as input after a

reset

 opera 

tion. If

markpos

 is not

 1

, then all bytes from positions

buf[markpos]

 through

buf[pos 1]

 must remain in the buffer array (though they may be moved to

another place in the buffer array, with suitable adjustments to the values of

count

,

pos

, and

markpos

); they may not be discarded unless and until the difference

between

pos

 and

markpos

 exceeds

marklimit

.

22.10.5

protected int marklimit;

Whenever the difference between

pos

 and

markpos

 exceeds

marklimit

, then the

mark may be dropped by setting

markpos

 to

 1

.

22.10.6

public BufferedInputStream(InputStream in)

This constructor initializes a newly created

BufferedInputStream

 by saving its

argument, the input stream

in

, for later use. An internal buffer array is created and

stored in

buf

.

22.10.7

public BufferedInputStream(InputStream in, int size)

This constructor initializes a newly created

BufferedInputStream

 by saving its

argument, the input stream

in

, for later use. An internal buffer array of length

size

 is created and stored in

buf

.

22.10.8

public int read() throws IOException

See the general contract of the

read

 method of

InputStream

 ( 22.3.1).

Overrides the

read

 method of

FilterInputStream

 ( 22.9.3).
