MetaIO * avfDecoder::doCreateTagger

(

void

)

[virtual]

Create a MetaIO object for the format.

This method should be overwritten by subclasses to return an instance of the appropriate MetaIO subtype. It is used by Decoder::getMetadata, Decoder::readMetadata and Decoder::commitMetadata.

The default implementation returns a NULL pointer, which essentially means, that if the decoder does not overrider this method or all of the users (see previous paragraph), files that the decoder supports cannot be indexed using metadata in the file.

e.g. the avf decoder (AvfDecoder) implements this, whereas the audio CD decoder (CdDecoder) does not.

Returns:

an instance of MetaIO owned by the caller

Reimplemented from Decoder.

Definition at line 501 of file avfdecoder.cpp.

void avfDecoder::run

(

void

)

[private, virtual]

Runs the Qt event loop unless we have a QRunnable, in which case we run the runnable run instead.

Note:

If you override this method you must call RunProlog before you do any work and RunEpilog before you exit the run method.

Reimplemented from MThread.
