Abstract Value Members

  1. abstract def init(index: Int, iters: Array[Iterator[InternalRow]]): Unit

    Initializes from array of iterators of InternalRow.

  2. abstract def processNext(): Unit

    Processes the input until have a row as output (currentRow).

    Processes the input until have a row as output (currentRow).

    After it's called, if currentRow is still null, it means no more rows left.
