32 * the RenderThread to avoid having mutual exclusion locks or messages back to the UpdateThread.
39 * @param[in] glSyncAbstraction The GlSyncAbstraction
40 * @param[in] resourceId The resource ID of the framebuffer texture being tracked
42 RenderTracker(Integration::GlSyncAbstraction& glSyncAbstraction);
46 * Delete any outstanding sync objects?
51 * Creates a sync object for this tracker. Will delete any existing sync object.
53 void CreateSyncObject();
56 * Check the GL Sync objects. This is called from Render Thread.
57 * If the GlSyncObject has been triggered, then atomically set the sync trigger
59 void PollSyncObject();
62 * Check the sync trigger. This is called from Update Thread, so atomically reads the sync trigger
63 * It clears the sync trigger if it was set.
64 * @return true if the tracker has been synced
69 * Atomically reset the sync trigger. This may be called from any thread
74 * Atomically sets the sync trigger. This may be called from any thread
