* * Gst::IndexEntry::ID: the description of the ID, as a String.
* * Gst::IndexEntry::ASSOCIATION: an Array that contains the number of associations, a Gst::Format, the value of the format and the association flags (see Gst::Index::AssocFlags).
* * Gst::IndexEntry::FORMAT: an Array that contains a Gst::Format and its value.
* * Gst::IndexEntry::OBJECt: not yet implemented.

* Returns: the internal data of the entry.
