| Invoked when data for the blob is received. | |
| virtual void | initializeFromCachedUnit (const QQmlPrivate::CachedQmlUnit *)=0 |
| virtual void | done () |
| Invoked once data has either been received or a network error occurred, and all dependencies are complete. | |
| virtual void | dependencyError (QQmlDataBlob *) |
| Called if blob, which was previously waited for, has an error. | |
| virtual void | dependencyComplete (QQmlDataBlob *) |
| Called if blob, which was previously waited for, has completed. | |

| Called when all blobs waited for have completed. | |
| virtual void | downloadProgressChanged (qreal) |
| Called when the download progress of this blob changes. | |
| virtual void | completed () |
