Unflatten

Reads this flattened Cyberdog item from a buffer.

long Unflatten (in Ptr buffer);

buffer

A pointer to a data buffer containing the flattened CyberItem object.

return value

The number of bytes read from the buffer.

DISCUSSION

This method should restore a Cyberdog item to its saved state from a flat representation stored in a buffer. The superclass implementation returns 0. This method is called by the CyberSession::CreateCyberItemFromSU method. The format of a flattened Cyberdog item is described in Table 7-1 (page 227).

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.
