@Deprecated public class StringBufferInputStream extends InputStream
StringReader
class.This class allows an application to create an input stream in which the bytes read are supplied by the contents of a string. Applications can also read bytes from a byte array by using a ByteArrayInputStream
.
Only the low eight bits of each character in the string are used by this class.

- 1.0

Constructor Detail
StringBufferInputStream
public StringBufferInputStream(String s)
Creates a string input stream to read data from the specified string.
- Parameters:
-
s
- the underlying input buffer.
Method Detail
read
public int read()
Reads the next byte of data from this input stream. The value byte is returned as an int
in the range 0
to 255
. If no byte is available because the end of the stream has been reached, the value -1
is returned.
The read
method of StringBufferInputStream
cannot block. It returns the low eight bits of the next character in this input stream's buffer.
- Specified by:
-
read
in classInputStream
- Returns:
- the next byte of data, or
-1
if the end of the stream is reached.
read
public int read(byte[] b, int off, int len)
Reads up to len
bytes of data from this input stream into an array of bytes.
The read
method of StringBufferInputStream
cannot block. It copies the low eight bits from the characters in this input stream's buffer into the byte array argument.
- Overrides:
-
read
in classInputStream
- Parameters:
-
b
- the buffer into which the data is read. -
off
- the start offset of the data. -
len
- the maximum number of bytes read. - Returns:
- the total number of bytes read into the buffer, or
-1
if there is no more data because the end of the stream has been reached. - See Also:
InputStream.read()
skip
public long skip(long n)
Skips n
bytes of input from this input stream. Fewer bytes might be skipped if the end of the input stream is reached.
- Overrides:
-
skip
in classInputStream
- Parameters:
-
n
- the number of bytes to be skipped. - Returns:
- the actual number of bytes skipped.
available
public int available()
Returns the number of bytes that can be read from the input stream without blocking.
- Overrides:
-
available
in classInputStream
- Returns:
- the value of
count - pos
, which is the number of bytes remaining to be read from the input buffer.
reset
public void reset()
Resets the input stream to begin reading from the first character of this input stream's underlying buffer.
- Overrides:
-
reset
in classInputStream
- See Also:
-
InputStream.mark(int)
