+/**
+ * Note:
+ *
+ * The FTS calls a slot of the calling object (CO) to send the requestData to the CO.
+ * This slot needs to be implemented by the calling object (CO):
+ *
+ * public Q_SLOTS:
+ *   void handleFunctionTopicRequest(const rti::core::SampleIdentity &requestIdentity, const TOPICTYPE_REQUEST &requestData);
+ *
+ * The CO processes the request and sends the feedback (and possible reply data) back to the FTS
+ * by calling the method:
+ *
+ *   void sendReply(const rti::core::SampleIdentity &requestIdentity, const QVector<TOPICTYPE_REPLY> &replyData )
+ *
+ *
+ * - The FTS cannot use SIGNALS, because templates and QObject are incompatible.
+ * - The FTS and the CO are in different threads
+ *
+ * => reply data will be stored in a queue (std:queue) and the handling is done by a semaphore (QSemaphore)
+ *
