Detailed Description

A class for pluggable file type resolution.

This class is used to add extend TagLib's very basic file name based file type resolution.

This can be accomplished with:

class MyFileTypeResolver : FileTypeResolver
{
{
if(someCheckForAnMP3File(fileName))
return new TagLib::MPEG::File(fileName);
return 0;
}
}
FileRef::addFileTypeResolver(new MyFileTypeResolver);

Naturally a less contrived example would be slightly more complex. This can be used to plug in mime-type detection systems or to add new file types to TagLib.

virtual File* TagLib::FileRef::FileTypeResolver::createFile ( FileName  fileName,
bool  readAudioProperties = true,
AudioProperties::ReadStyle  audioPropertiesStyle = AudioProperties::Average 
) const
pure virtual

This method must be overridden to provide an additional file type resolver. If the resolver is able to determine the file type it should return a valid File object; if not it should return 0.

Note
The created file is then owned by the FileRef and should not be deleted. Deletion will happen automatically when the FileRef passes out of scope.
