Iterable evaluateIterable(Evaluator evaluator)

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.

evaluateMemberIterable

Iterable<Member> evaluateMemberIterable(Evaluator evaluator)

evaluateTupleIterable

Iterable<Member[]> evaluateTupleIterable(Evaluator evaluator)
