ExternalizeContent

Writes this Cyberdog item to storage in multiple representations.

void ExternalizeContent (in ODStorageUnit su);

su

The ODStorageUnit object in which to store the CyberItem object.

DISCUSSION

This method should write this Cyberdog item to a storage unit in multiple formats, in decreasing order of fidelity. By convention, Cyberdog items are written in at least two formats: the Cyberdog item kind (kCyberItemKind) and the URL text. This method is called when a Cyberdog item must be written to a storage unit, such as when a Cyberdog item is dragged.

You read a Cyberdog item that has been written to a storage unit by calling the CyberSession::CreateCyberItemFromSU method.

If you subclass CyberItem, you must override this method. Your override must not call its inherited method; that is, your override method must implement this method's functionality completely.
