Type Members

1. class Accumulable[R, T] extends Serializable

   A data type that can be accumulated, ie has an commutative and associative "add" operation, but where the result type, R, may be different from the element type being added, T.

2. trait AccumulableParam[R, T] extends Serializable

   Helper object defining how to accumulate values of a particular type.

3. class Accumulator[T] extends Accumulable[T, T]

   A simpler value of Accumulable where the result type being accumulated is the same as the types of elements being merged, i.

4. trait AccumulatorParam[T] extends AccumulableParam[T, T]

   A simpler version of org.apache.spark.AccumulableParam where the only data type you can add in is the same type as the accumulated value.
