Enclosing class:

SetFunDef

public static class SetFunDef.ExprIterCalc
extends AbstractIterCalc

Method Detail

getCalcs

public IterCalc[] getCalcs()

Description copied from class: AbstractCalc

Returns this expression's child expressions.

Overrides:

getCalcs in class AbstractCalc

evaluateIterable

public TupleIterable evaluateIterable(Evaluator evaluator)

Description copied from interface: IterCalc

Evaluates an expression to yield an Iterable of members or tuples.

The Iterable is immutable.

Parameters:

evaluator - Evaluation context

Returns:

An Iterable of members or tuples, never null.
