Constructor Detail

NonshareableBufferedOutputStream

public NonshareableBufferedOutputStream(java.io.OutputStream out)

Creates a new buffered output stream to write data to the specified underlying output stream.

Parameters:

out - the underlying output stream.

NonshareableBufferedOutputStream

public NonshareableBufferedOutputStream(java.io.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:

java.lang.IllegalArgumentException - if size <= 0.

NonshareableBufferedOutputStream

public NonshareableBufferedOutputStream(java.io.OutputStream out,
                                        byte[] buf)

Creates a new buffered output stream to write data to the specified underlying output stream with the specified buffer.

Parameters:

out - the underlying output stream.

buf - the buffer to use

Throws:

java.lang.IllegalArgumentException - if size <= 0.

Method Detail

write

public void write(int b)
           throws java.io.IOException

Writes the specified byte to this buffered output stream.

Overrides:

write in class java.io.FilterOutputStream

Parameters:

b - the byte to be written.

Throws:

java.io.IOException - if an I/O error occurs.

write

public void write(byte[] b)
           throws java.io.IOException

Writes b.length bytes to this output stream.

The write method of FilterOutputStream calls its write method of three arguments with the arguments b, 0, and b.length.

Note that this method does not call the one-argument write method of its underlying stream with the single argument b.

Overrides:

write in class java.io.FilterOutputStream

Parameters:

b - the data to be written.

Throws:

java.io.IOException - if an I/O error occurs.

See Also:

FilterOutputStream.write(byte[], int, int)

write

public void write(byte[] b,
                  int off,
                  int len)
           throws java.io.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 java.io.FilterOutputStream

Parameters:

b - the data.

off - the start offset in the data.

len - the number of bytes to write.

Throws:

java.io.IOException - if an I/O error occurs.

flush

public void flush()
           throws java.io.IOException

Flushes this buffered output stream. This forces any buffered output bytes to be written out to the underlying output stream.

Specified by:

flush in interface java.io.Flushable

Overrides:

flush in class java.io.FilterOutputStream

Throws:

java.io.IOException - if an I/O error occurs.
