Wraps an existing OutputStream and buffers the output.
Expensive interaction with the underlying input stream is minimized, since
most (smaller) requests can be satisfied by accessing the buffer alone. The
drawback is that some extra space is required to hold the buffer and that
copying takes place when flushing that buffer, but this is usually outweighed
by the performance benefits.

The buffer containing the bytes to be written to the target stream.
Constructs a new BufferedOutputStream, providing out with a buffer
of 8192 bytes.
| out | the OutputStream the buffer writes to.
|
|---|
Constructs a new BufferedOutputStream, providing out with size bytes
of buffer.
| out | the OutputStream the buffer writes to. |
|---|---|
| size | the size of buffer in bytes. |
| IllegalArgumentException | if size <= 0.
|
|---|
Closes this stream. This implementation closes the target stream.
| IOException |
|---|
Flushes this stream to ensure all pending data is written out to the target stream. In addition, the target stream is flushed.
| IOException | if an error occurs attempting to flush this stream. |
|---|
Writes count bytes from the byte array buffer starting at
offset to this stream. If there is room in the buffer to hold the
bytes, they are copied in. If not, the buffered bytes plus the bytes in
buffer are written to the target stream, the target is flushed,
and the buffer is cleared.
| buffer | the buffer to be written. |
|---|---|
| offset | the start position in buffer from where to get bytes. |
| length | the number of bytes from buffer to write to this
stream. |
| IndexOutOfBoundsException | if offset < 0 or length < 0, or if
offset + length is greater than the size of
buffer. |
|---|---|
| IOException | if an error occurs attempting to write to this stream. |
| NullPointerException | if buffer is null. |
| ArrayIndexOutOfBoundsException | If offset or count is outside of bounds. |
Writes one byte to this stream. Only the low order byte of the integer
oneByte is written. If there is room in the buffer, the byte is
copied into the buffer and the count incremented. Otherwise, the buffer
plus oneByte are written to the target stream, the target is
flushed, and the buffer is reset.
| oneByte | the byte to be written. |
|---|
| IOException | if an error occurs attempting to write to this stream. |
