Method Detail

evaluateList

TupleList evaluateList(Evaluator evaluator)

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.
