31 * This class is used to communicate with Fence Sync objects, keeping access solely in
32 * the RenderThread to avoid having mutual exclusion locks or messages back to the UpdateThread.
48 * Creates a sync object for this tracker. Will delete any existing sync object.
50 * @param[in] graphicsController The graphics subsystem
52 Graphics::SyncObject* CreateSyncObject(Graphics::Controller& graphicsController);
55 * Check the Sync objects. This is called from Render Thread.
56 * If the SyncObject has been triggered, then atomically set the sync trigger
58 void PollSyncObject();
61 * Check the sync trigger. This is called from Update Thread, so atomically reads the sync trigger
62 * It clears the sync trigger if it was set.
63 * @return true if the tracker has been synced
68 * Atomically reset the sync trigger. This may be called from any thread
73 * Atomically sets the sync trigger. This may be called from any thread
