|
|
// Description : A StreamWriter object is used to write sequential
|
|
// binary data directly to an ostream. Its interface is
|
|
// very similar to Datagram by design; it's primarily
|
|
// intended as a convenience to eliminate the overhead
|
|
// of writing bytes to a Datagram and then writing the
|
|
// Datagram to a stream.
