• Field Details

  • 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 Details

  • 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. Throws: IllegalArgumentException - if size <= 0.

• Method Details

  • write

    public 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.

  • write

    public 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. IndexOutOfBoundsException - If off is negative, len is negative, or len is greater than b.length - off See Also:

    • FilterOutputStream.write(int)

  • flush

    public void flush() throws 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 Flushable Overrides: flush in class FilterOutputStream Throws: IOException - if an I/O error occurs. See Also:

    • FilterOutputStream.out
