public class BufferedOutputStream
extends FilterOutputStream
The class implements a buffered output stream. By setting up such an output stream, an application can write bytes to the underlying output stream without necessarily causing a call to the underlying system for each byte written. The data is written into a buffer, and then written to the underlying stream if the buffer reaches its capacity, the buffer output stream is closed, or the buffer output stream is explicity flushed.

Variable Index

o buf
The buffer where data is stored.
o count
The number of valid bytes in the buffer.

Constructor Index

o BufferedOutputStream(OutputStream)
Creates a new buffered output stream to write data to the specified underlying output stream with a default 512-byte buffer size.
o BufferedOutputStream(OutputStream, int)
Creates a new buffered output stream to write data to the specified underlying output stream with the specified buffer size.

Method Index

o flush()
Flushes this buffered output stream.
o write(byte[], int, int)
Writes len bytes from the specified byte array starting at offset off to this buffered output stream.
o write(int)
Writes the specified byte to this buffered output stream.

Variables

o buf 
  protected byte buf[]
The buffer where data is stored.

o count 
  protected int count
The number of valid bytes in the buffer.

Constructors

o BufferedOutputStream 
  public BufferedOutputStream(OutputStream out)
Creates a new buffered output stream to write data to the specified underlying output stream with a default 512-byte buffer size.

Parameters:
out - the underlying output stream.
o BufferedOutputStream 
  public BufferedOutputStream(OutputStream out,
                              int size)
Creates a new buffered output stream to write data to the specified underlying output stream with the specified buffer size.

Parameters:
out - the underlying output stream.
size - the buffer size.

Methods

o write 
  public synchronized void write(int b) throws IOException
Writes the specified byte to this buffered output stream.

Parameters:
b - the byte to be written.
Throws: IOException
if an I/O error occurs.
Overrides:
write in class FilterOutputStream
o write 
  public synchronized void write(byte b[],
                                 int off,
                                 int len) throws IOException
Writes len bytes from the specified byte array starting at offset off to this buffered output stream.

Parameters:
b - the data.
off - the start offset in the data.
len - the number of bytes to write.
Throws: IOException
if an I/O error occurs.
Overrides:
write in class FilterOutputStream
o flush 
  public synchronized void flush() throws IOException
Flushes this buffered output stream. This forces any buffered output bytes to be written out to the underlying output stream.

Throws: IOException
if an I/O error occurs.
Overrides:
flush in class FilterOutputStream
