Constructor Detail

BaseListCalc

protected BaseListCalc(ResolvedFunCall call,
                       Calc[] calcs,
                       boolean mutable)

Method Detail

evaluateList

public TupleList evaluateList(Evaluator evaluator)

Description copied from interface: ListCalc

Evaluates an expression to yield a list of tuples.

The list is immutable if Calc.getResultStyle() yields ResultStyle.MUTABLE_LIST. Otherwise, the caller must not modify the list.

Parameters:

evaluator - Evaluation context

Returns:

A list of tuples, never null.

makeList

protected abstract TupleList makeList(TupleList l1,
                                      TupleList l2)
