feat(api/iota): endofunctors by poolcritter · Pull Request #1191 · FallingColors/HexMod

poolcritter · 2026-07-08T06:00:29Z

adds visit and visitChildren to iotas letting you apply a UnaryOperator to an entire tree of them. this is like hexal's IMappableIota except I don't know if that does self pre or post (or if it does self at all). awa.

I haven't tested this in prod; hex doesn't have anything that would use this yet. @IridescentVoid I believe you have a patch that may want to use this?

Issue: closes #1083
Prereq: #1195

IridescentVoid

github ate the comment I left on the file. see review below instead.

IridescentVoid

Code-Review: -1

Implementation of visitChildren should be made more readable. I would like to at least see full-length variable names.

I'd also like feedback from others on the API design since changing this later would be a breaking change.

+    @Override
+    protected Iota visitChildren(UnaryOperator<Iota> visitor) {
+        var out = new ArrayList();


Suggested change

var out = new ArrayList();

var out = new ArrayList<Iota>();

~~Other than this, looks good to merge if there are no other comments on the api design.~~ Not good to merge, I'm pretty sure the logic is wrong.

IridescentVoid

Code-Review: -1

Noticed a pretty major logic bug that I somehow missed during the initial review pass. We should probably test this more throughly before merging.

Request on using ArrayList<Iota> still applies.

IridescentVoid · 2026-07-09T22:34:59Z

+        var out = new ArrayList();
+        boolean conserve = true;
+        for (Iota orig : getList()) {
+            var replacement = visitor.apply(orig);


Suggested change

var replacement = visitor.apply(orig);

var replacement = orig.visit(visitor);

@IridescentVoid

adds `visit` and `visitChildren` to iotas letting you apply a UnaryOperator to an entire tree of them. this is like hexal's IMappableIota except I don't know if that does self pre or post (or if it does self at all). awa. I haven't tested this in prod; hex doesn't have anything that would use this yet. @IridescentVoid I believe you have a patch that may want to use this?

LGTM

Also closes #1195, since the changes there are bundled here.
