53 * Non virtual destructor. Not intended as base class.
58 * @brief Initializes the thread controller
60 * Will do any required initialiszation, e.g. initialize EGL, create threads (if required), etc.
62 * @note When this function returns, the application Init signal should be emitted
67 * @brief Called AFTER the Init signal has been emitted.
69 * In other words, should be called AFTER the Init signal has been emitted and all messages for the first scene
70 * have been queued for update to process.
75 * @brief When called, update and rendering is paused.
80 * @brief Resumes update/rendering after a previous pause.
85 * @brief Stops update/rendering altogether.
87 * Will shutdown EGL, destroy threads (if required) etc.
92 * @brief Called by the adaptor when core requires another update
97 * @brief Called by the adaptor when core requires one update
99 * @note If Adaptor is paused, we do one update/render only
