public class: BufferedOutputStream [javadoc | source]
java.lang.Object
   java.io.OutputStream
      java.io.FilterOutputStream
         java.io.BufferedOutputStream

All Implemented Interfaces:
    Flushable, Closeable

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.
Field Summary
protected  byte[] buf    The internal buffer where data is stored. 
protected  int count    The number of valid bytes in the buffer. This value is always in the range 0 through buf.length; elements buf[0] through buf[count-1] contain valid byte data. 
Fields inherited from java.io.FilterOutputStream:
out
Constructor:
 public BufferedOutputStream(OutputStream out) 
    Creates a new buffered output stream to write data to the specified underlying output stream.
    Parameters:
    out - the underlying output stream.
 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.
    Throws:
    IllegalArgumentException - if size <= 0.
    exception: IllegalArgumentException - if size <= 0.

Method from java.io.BufferedOutputStream Detail:
 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.
 public synchronized  void write(int b) throws IOException 
    Writes the specified byte to this buffered output stream.
 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.

    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.
