ODBoolean IsValid ();

return value

kODTrue if this embedded-frames iterator is valid, otherwise kODFalse.

DISCUSSION

A client of this embedded-frames iterator calls this method if it wants to ensure that it makes calls only to a valid embedded-frames iterator, without generating an exception.

OVERRIDING

When you subclass ODEmbeddedFramesIterator, 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.
