AUTOUNLINK = [ "COsdItem", "COsdMenu", "CMenuText" ]
################################################################################
#
# Add auto unlink code to SWIG director destructors like:
#
# SwigDirector_<class>::~SwigDirector_<class>() {
# SWIG_RubyUnlinkObjects(this);
# SWIG_RubyRemoveTracking(this);
# }
#
# With this code, when a C++ instance is delete, it will automatically remove
# itself from the list of tracked objects and unlink itself from the Ruby object
# it is used by. This means, that any call to a method of the C++ class from the
# Ruby object will now throw an ObjectPreviouslyDeleted exception.
