RowIterator

An internal iterator interface which presents a more restrictive API than scala.collection.Iterator.

One major departure from the Scala iterator API is the fusing of the hasNext() and next() calls: Scala's iterator allows users to call hasNext() without immediately advancing the iterator to consume the next row, whereas RowIterator combines these calls into a single advanceNext() method.

new RowIterator()

Abstract Value Members

abstract def advanceNext(): Boolean

Advance this iterator by a single row.
Advance this iterator by a single row. Returns false if this iterator has no more rows and true otherwise. If this returns true, then the new row can be retrieved by calling getRow.
abstract def getRow: InternalRow

Retrieve the row from this iterator.
Retrieve the row from this iterator. This method is idempotent. It is illegal to call this method after advanceNext() has returned false.
