public abstract class AbstractValuesProcessor extends Object
Subclass of AbstractTupleProcessor provides a series of tuple. It takes a series of iterators of
Values and produces a stream of tuple.
The subclass implements the
next() method to provide the output of the stream. It can choose to return null in
next() to indicate that this particular iteration is a no-op. SQL processors depend on this semantic to implement filtering and nullable records.
