ExpressionFunctionValueSource lazily evaluates in doubleValues: an expression like
condition ? f1 : f2 will only evaluate one of f1 or f2. At the same time, the advanceExact() call is greedy -- when you advance that expression it will also advance both f1 and f2. But here's the thing: it always returns true, regardless of whether f1 and f2 advance. Which makes sense from the point of view of the lazy evaluation -- if condition is true we don't care whether f2 advances or not. My question is whether we could defer these child advanceExact calls until ExpressionFunctionValues.doubleValue()? --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
