/// It contains parameters of input, output and shared parameters.
/// Using the isSupported() method, the StreamParameters can be
/// checked if opening a Stream using this StreamParameters would
/// succeed or not. Accessors are provided to higher-level parameters
/// aswell as the lower-level parameters which are mainly intended for
/// internal use.
