Abstract Value Members
- abstract def init(index: Int, iters: Array[Iterator[InternalRow]]): Unit
Initializes from array of iterators of InternalRow.
- 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.
