◆ MDUpdateListener()

ilLMObject::MDUpdateListener ( string $a_element )

Meta data update listener Important note: Do never call create() or update() method of ilObject here.

It would result in an endless loop: update object -> update meta -> update object -> ... Use static _writeTitle() ... methods instead.

Parameters

string $a_element md element
