BufferedOutputStream
final public class BufferedOutputStream extends FilterOutputStream (Code)
This class is like the java.io.BufferedOutputStream but it extends it with a logic to count the number of bytes written to the output stream.

version:
   CVS $Id: BufferedOutputStream.java 433543 2006-08-22 06:22:54Z crossley $
since:
   2.1


Field Summary
protected  bytebuf
    
protected  intcount
    

Constructor Summary
public  BufferedOutputStream(OutputStream out)
     Creates a new buffered output stream to write data to the specified underlying output stream with a default 8192-byte buffer size.
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.

Method Summary
public  voidclearBuffer()
    
public  voidclose()
     Closes this buffered output stream.
public  voidflush()
     Flushes this buffered output stream.
public  intgetCount()
    
public  voidrealFlush()
     Flushes this buffered output stream.
public  voidwrite(int b)
     Writes the specified byte to this buffered output stream.
public  voidwrite(byte b, int off, int len)
     Writes len bytes from the specified byte array starting at offset off to this buffered output stream.

Ordinarily this method stores bytes from the given array into this stream's buffer, flushing the buffer to the underlying output stream as needed.


Field Detail
buf
protected byte buf(Code)



count
protected int count(Code)




Constructor Detail
BufferedOutputStream
public BufferedOutputStream(OutputStream out)(Code)
Creates a new buffered output stream to write data to the specified underlying output stream with a default 8192-byte buffer size.
Parameters:
  out - the underlying output stream.



BufferedOutputStream
public BufferedOutputStream(OutputStream out, int size)(Code)
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.
Parameters:
  size - the buffer size.
exception:
  IllegalArgumentException - if size <= 0.




Method Detail
clearBuffer
public void clearBuffer()(Code)
Clear/reset the buffer



close
public void close() throws IOException(Code)
Closes this buffered output stream. Flush before closing.
exception:
  IOException - if an I/O error occurs.



flush
public void flush() throws IOException(Code)
Flushes this buffered output stream. We don't flush here, flushing is done during closing.
exception:
  IOException - if an I/O error occurs.



getCount
public int getCount()(Code)
Return the size of the current buffer



realFlush
public void realFlush() throws IOException(Code)
Flushes this buffered output stream.



write
public void write(int b) throws IOException(Code)
Writes the specified byte to this buffered output stream.
Parameters:
  b - the byte to be written.
exception:
  IOException - if an I/O error occurs.



write
public void write(byte b, int off, int len) throws IOException(Code)
Writes len bytes from the specified byte array starting at offset off to this buffered output stream.

Ordinarily this method stores bytes from the given array into this stream's buffer, flushing the buffer to the underlying output stream as needed. If the requested length is at least as large as this stream's buffer, however, then this method will flush the buffer and write the bytes directly to the underlying output stream. Thus redundant BufferedOutputStreams will not copy data unnecessarily.
Parameters:
  b - the data.
Parameters:
  off - the start offset in the data.
Parameters:
  len - the number of bytes to write.
exception:
  IOException - if an I/O error occurs.
