Streaming content interface to write bytes to an output stream.
Implementations don't need to be thread-safe.
writeTo(OutputStream out) (deprecated)
public abstract void writeTo(OutputStream out)
Writes the byte content to the given output stream.
Implementations must not close the output stream, and instead should flush the output
stream. Some callers may assume that the output stream has not been closed, and will fail to
work if it has been closed.
