22.7.4

public StringBufferInputStream(String s)

throws NullPointerException

This constructor initializes a newly created

StringBufferInputStream

 so that it

uses

s

 as its buffer array. The initial value of

pos

 is

0

 and the initial value of

count

 is the length of

buffer

.

22.7.5

public int read()

If

pos

 equals

count

, then

 1

 is returned to indicate end of file. Otherwise, the

value

buffer[pos]&0xff

 is returned; just before the return,

1

 is added to

pos

.

Implements the

read

 method of

InputStream

 ( 22.3.1).

22.7.6

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

throws NullPointerException,

IndexOutOfBoundsException

If

pos

 equals

count

, then

 1

 is returned to indicate end of file. Otherwise, the

number

k

 of bytes read is equal to the smaller of

len

 and

count pos

. If

k

 is posi 

tive, then bytes

buffer[pos]

 through

buffer[pos+k 1]

 are copied into

b[off]

through

b[off+k 1]

 in the manner performed by

System.arraycopy

( 20.18.16). The value

k

 is added into

pos

 and

k

 is returned.

Overrides the

read

 method of

InputStream

 ( 22.3.3).

22.7.7

public long skip(long n)

The actual number

k

 of bytes to be skipped is equal to the smaller of

n

 and

count pos

. The value

k

 is added into

pos

 and

k

 is returned.

Overrides the

skip

 method of

InputStream

 ( 22.3.4).

22.7.8

public int available()

The quantity

count pos

 is returned.

Overrides the

available

 method of

InputStream

 ( 22.3.5).

22.7.9

public void reset()

The value of

pos

 is set to

0

.

Overrides the
