This CStdOutStream derived class allow printing to standard out, normally the console text output.
Please notice CStdOutStream's are binary streams, so "char *" data types only should be used if textual outputs are desired.

CSerializablePtr | ReadObject () |
Reads an object from stream, its class determined at runtime, and returns a smart pointer to the object. | |
void | ReadObject (CSerializable *existingObj) |
Reads an object from stream, where its class must be the same as the supplied object, where the loaded object will be stored in. | |

bool | receiveMessage (utils::CMessage &msg) |
Tries to receive a message from the device. | |
bool | getline (std::string &out_str) |
