void | setError (const QQmlError &) |
Mark this blob as having errors. | |

void | setError (const QString &description) |
void | addDependency (QQmlDataBlob *) |
Wait for blob to become complete or to error. | |
virtual void | dependencyError (QQmlDataBlob *) |
Called if blob, which was previously waited for, has an error. | |
virtual void | allDependenciesDone () |
Called when all blobs waited for have completed. | |
virtual void | downloadProgressChanged (qreal) |
Called when the download progress of this blob changes. | |
virtual void | completed () |
Invoked on the main thread sometime after done() was called on the load thread. | |

Invoked when data for the blob is received.
Implementors should use this callback to determine a blob's dependencies. Within this callback you may call setError() or addDependency().

Invoked once data has either been received or a network error occurred, and all dependencies are complete.
You can set an error in this method, but you cannot add new dependencies. Implementors should use this callback to finalize processing of data.
The default implementation does nothing.
XXX Rename processData() or some such to avoid confusion between done() (processing thread) and completed() (main thread)
