Type Members

1. trait CatalystAverageable[In, Out] extends AnyRef

   

   When averaging Spark doesn't change these types: - BigDecimal -> BigDecimal - Double -> Double But it changes these types : - Int -> Double - Short -> Double - Long -> Double

2. trait CatalystCast[A, B] extends AnyRef

   

3. trait CatalystNumeric[A] extends AnyRef

   

4. trait CatalystOrdered[A] extends AnyRef

   

   Types that can be ordered/compared by Catalyst.

5. trait CatalystSummable[A, Out] extends AnyRef

   

   When summing Spark doesn't change these types: - Long -> Long - BigDecimal -> BigDecimal - Double -> Double

   When summing Spark doesn't change these types: - Long -> Long - BigDecimal -> BigDecimal - Double -> Double

   For other types there are conversions: - Int -> Long - Short -> Long

6. trait CatalystVariance[T] extends AnyRef
