The method is designed to cancel changes made in an entity instance.
procedure Cancel; overload;
The method cancels modifications made in an entity instance. If an instance was deleted with TCustomEntityContext.Delete, the entity is restored from the object cache on the method execution, database access doesn't occur. The method cancels only those changes, that were not saved with the TCustomEntityContext.Save or TDataContext.SubmitChanges methods.
The method performs a non-cascade cancelling. For cancel the entity changes cascade use the overloaded Cancel method instead.
