A custom implementation of the Sitecore IIntelResultTransformer to transform a DateTable with some useful properties

SampleOrderResultTransformer.cs

public class SampleOrderResultTransformer : IIntelResultTransformer, IResultTransformer<DataTable>
{
    private ResultSetExtender resultSetExtender;

    public SampleOrderResultTransformer()
    {
        this.resultSetExtender = ClientFactory.Instance.GetResultSetExtender();
    }

    public SampleOrderResultTransformer(ResultSetExtender resultSetExtender)
    {
        this.resultSetExtender = resultSetExtender;
    }

    public object Transform(ResultSet<DataTable> resultSet)
    {
        Assert.ArgumentNotNull((object) resultSet, "resultSet");
        this.resultSetExtender.AddRecency(resultSet, "VisitStartDateTime");
        return (object) resultSet;
    }
}
