IsLastModTimeAvailable

Tests whether the last modification time is available for data in this Cyberdog stream.

ODBoolean IsLastModTimeAvailable ();

return value

kODTrue if the last modification time is available; otherwise, kODFalse.

DISCUSSION

You call this method to determine whether the last modification time is available for data downloaded by a stream object. If the last modification time is available, you can retrieve it by calling the GetLastModTime method. If GetLastModTime returns kCDLastModTimeUnknowable, you do not need to continue to poll IsLastModTimeAvailable.

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