IsTotalDataSizeAvailable(Cyberdog)

Inside Macintosh: Cyberdog Programmer's Kit / Part 3 - Cyberdog Reference

Chapter 7 - Classes and Methods / CyberStream

IsTotalDataSizeAvailable
Tests whether the total size of this Cyberdog stream is available.
ODBoolean IsTotalDataSizeAvailable ();
return value
kODTrue if the total data size is available; otherwise, kODFalse.

DISCUSSION
You call this method to determine whether the total number of bytes to be downloaded by a stream object is available. If the total size is available, you can retrieve it by calling the GetTotalDataSize method. If GetTotalDataSize returns kCDTotalDataSizeUnknowable, you do not need to continue to poll IsTotalDataSizeAvailable.
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.
