Syntax
public interface IQueryResultRemarks
A custom dataset implementor must supply an implementation of this interface. It is used as the return value from the ICustomDataSet.Query method, and should iterate over all features returned from the query.
Exceptions that are thrown by custom object implementations will be logged and then propagated by Carmenta Engine as an EngineException to the application. Also, the only way a C++ custom object implementation can include a relevant error message to an application is by throwing an EngineException.
