- type resolution for the function parameters
-
postOptimizationVerification
Description copied from interface:PostOptimizationVerificationAwareValidates the implementing expression - discovered failures are reported to the givenFailuresclass.Example: the
Bucketfunction, which produces buckets over a numerical or date field, based on a number of literal arguments needs to check if its arguments are all indeed literals. This is how this verification is performed:@Override public void postOptimizationVerification(Failures failures) { String operation = sourceText(); failures.add(isFoldable(buckets, operation, SECOND)) .add(from != null ? isFoldable(from, operation, THIRD) : null) .add(to != null ? isFoldable(to, operation, FOURTH) : null); }- Specified by:
