public class WritableByteArray extends ByteArrayOutputStream
This saves memory over creating a new byte[] and ByteArrayOutputStream each time data is written.
Typical usage is something like the following:
WritableByteArray buffer = new WritableByteArray();
while (... loop condition ...) {
buffer.reset();
... write to buffer ...
byte[] data = buffer.getData();
int dataLength = buffer.getLength();
... write data to its ultimate destination ...
}
