java.io
class BufferedOutputStream

java.lang.Object extended by java.io.OutputStream extended by java.io.FilterOutputStream extended by java.io.BufferedOutputStream
All Implemented Interfaces:
Closeable, Flushable

Most common way to construct:

FileOutputStream fos = …;

BufferedOutputStream bos = new BufferedOutputStream(fos);

Based on 28 examples


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.

BufferedInputStream

FileOutputStream


Field Summary
protected byte[] buf
          The internal buffer where data is stored.

Field Detail

buf

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

count

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.
Constructor Detail

BufferedOutputStream

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.

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.
Method Detail

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.

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

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.

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.

Overrides:
write in class FilterOutputStream
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.

write

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

Overrides:
write in class FilterOutputStream
Parameters:
b - the byte to be written.
Throws:
IOException - if an I/O error occurs.
