Can we then make a single abstract evaluator for all three instead of just append/prepend? Let's call it AbstractArrayInsertEval and it's subclasses will define where it gets array / position / values from. Does it make sense? https://asterix-gerrit.ics.uci.edu/#/c/2739/1/asterixdb/asterix-runtime/src/main/java/org/apache/asterix/runtime/functions/FunctionCollection.java File asterixdb/asterix-runtime/src/main/java/org/apache/asterix/runtime/functions/FunctionCollection.java: Line 381: fc.addGenerated(ArrayPrependDescriptor.FACTORY); As I mentioned in the array_insert() review it looks like you cannot use code-gened runtime for these evaluators because inserted values can be null. -- To view, visit https://asterix-gerrit.ics.uci.edu/2739 To unsubscribe, visit https://asterix-gerrit.ics.uci.edu/settings Gerrit-MessageType: comment Gerrit-Change-Id: Iccfe54e126700724fd393b5c6a6de6f3aa6db9ce Gerrit-PatchSet: 1 Gerrit-Project: asterixdb Gerrit-Branch: master Gerrit-Owner: Ali Alsuliman <[email protected]> Gerrit-Reviewer: Ali Alsuliman <[email protected]> Gerrit-Reviewer: Anon.
