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 mp3 decoder (MadDecoder) implements this, whereas the audio CD decoder (CdDecoder) does not.

Returns:

an instance of MetaIO owned by the caller

Reimplemented from Decoder.
