Closeable
,AutoCloseable
Deprecated.
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.

Method Details
-
read
public int read()Deprecated.Reads the next byte of data from this input stream. The value byte is returned as anint
in the range0
to255
. If no byte is available because the end of the stream has been reached, the value-1
is returned.- Specified by:
read
in classInputStream
- Implementation Requirements:
- The
read
method ofStringBufferInputStream
cannot block. It returns the low eight bits of the next character in this input stream's buffer. - 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) Deprecated.Reads up tolen
bytes of data from this input stream into an array of bytes.- Overrides:
read
in classInputStream
- Implementation Requirements:
- The
read
method ofStringBufferInputStream
cannot block. It copies the low eight bits from the characters in this input stream's buffer into the byte array argument. - Parameters:
b
- the buffer into which the data is read.off
- the start offset in arrayb
at which the data is written.len
- the maximum number of bytes to 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:
-
skip
public long skip(long n) Deprecated.Skipsn
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.
- See Also:
-
available
public int available()Deprecated.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()Deprecated.Resets the input stream to begin reading from the first character of this input stream's underlying buffer.- Overrides:
reset
