public class BufferedOutputStream
extends FilterOutputStream

A buffered output stream. This stream lets you write characters to a stream without causing a write every time. The data is first written into a buffer. It is written to the actual stream when the buffer is full, or when the stream is flushed.

Version:: 1.12, 31 Jan 1995
Author:: Arthur van Hoff

buf: The buffer.
count: The number of bytes in the buffer.

BufferedOutputStream(OutputStream): Creates a new buffered stream with a default buffer size.
BufferedOutputStream(OutputStream, int): Creates a new buffered stream with a given buffer size.

flush(): Flushes the stream.
write(int): Writes a byte.
write(byte[], int, int): Writes a sub array of bytes.

buf

  protected byte buf[]

The buffer.

count

  protected int count

The number of bytes in the buffer.

BufferedOutputStream

  public BufferedOutputStream(OutputStream out)

Creates a new buffered stream with a default buffer size.

Parameters:: in - the input stream

BufferedOutputStream

  public BufferedOutputStream(OutputStream out,
                              int size)

Creates a new buffered stream with a given buffer size.

Parameters:: in - the input stream; size - the buffer size

write

  public synchronized void write(int b)

Writes a byte. Will block until the byte is actually written.

Throws: IOException: i/o error occurred
Overrides:: write in class FilterOutputStream

write

  public synchronized void write(byte b[],
                                 int off,
                                 int len)

Writes a sub array of bytes. To be efficient it should be overridden in a subclass.

Parameters:: b - the data to be written; off - the start offset in the data; len - the number of bytes that are written
Throws: IOException: i/o error occurred
Overrides:: write in class FilterOutputStream

flush

  public synchronized void flush()

Flushes the stream. This will write any buffered output bytes.

Throws: IOException: i/o error occurred
Overrides:: flush in class FilterOutputStream
