@property (nonatomic, assign) LTOcrProgressStatus status 
public OcrProgressStatus getStatus() 
public void setStatus(OcrProgressStatus value) 
property OcrProgressStatus Status { 
   OcrProgressStatus get(); 
   void set (    OcrProgressStatus ); 
} 
Status # get and set (IOcrProgressData) 

Property Value

The current status of the callback.
