Constructor Detail

IterableTupleListCalc

public IterableTupleListCalc(TupleIterCalc iterCalc)

Creates an IterableListCalc.

Parameters:

iterCalc - Calculation that returns an iterable.

Method Detail

evaluateTupleList

public java.util.List<Member[]> evaluateTupleList(Evaluator evaluator)

Description copied from interface: TupleListCalc

Evaluates an expression to yield a list of tuples.

Each tuple is represented by an array of members.

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.
