  - withTopNMetricVal
```
public DimValHolder.Builder withTopNMetricVal(Object topNMetricVal)
```
  - withDimValue
```
public DimValHolder.Builder withDimValue(Comparable dimValue,
                                         ColumnType type)
```
    This method is called by TopNResultBuilder.addEntry(java.lang.Comparable, java.lang.Object, java.lang.Object[]) to store query results. The method accepts a type argument because Jackson will deserialize numbers as integers instead of longs if they are small enough. Similarly, type mismatch can arise when using floats when Jackson deserializes numbers as doubles instead. This method will ensure that any added dimension value is converted to the expected type.
    
    Parameters:
    
    dimValue - Dimension value from TopNResultBuilder
    
    type - Type that dimValue should have, according to the output type of the DimensionSpec associated with dimValue from the calling TopNResultBuilder
