Gets or sets a caller-owned THPDFCancellationToken reference, or nil when document operations should not use a shared token
使用上の注意
- The document does not own or free the assigned token
- The token must remain valid for the complete load, render, optimisation, or validation call and for every progressive session that inherits it
- Clear the property before freeing the token and create a new token for a later operation because cancellation is one-shot
