Description copied from class: AudioFileWriter

This is called when a tag has to be written in a file. Three parameters are provided, the tag to write (not empty) Two randomaccessfiles, the first points to the file where we want to write the given tag, and the second is an empty temporary file that can be used if e.g. the file has to be bigger than the original.

If something has been written in the temporary file, when this method returns, the original file is deleted, and the temporary file is renamed the the original name

If nothing has been written to it, it is simply deleted.

This method can assume the raf, rafTemp are pointing to the first byte of the file. The subclass must not close these two files when the method returns.

Specified by:
