◆ dataReceived()

void QQmlScriptBlob::dataReceived ( const SourceCodeData & )

overrideprotectedvirtual

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().

Implements QQmlDataBlob.

Here is the call graph for this function:

◆ done()

void QQmlScriptBlob::done ( )

overrideprotectedvirtual

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)
