# Radix

|
Haxe port: in-place MSD radix sort (American flag sort) with an insertion sort fallback for small sub-ranges implemented in the Leenkx SDK by Riccardo Mazzucco

|
## Usage
|
||
|
|
|
||
|
|
```haxe
|
||
|
|
import radix.Radix;
|
||
|
|
|
||
|
|
// Stable sort: counting-sort scatter between `a` and `buffer`.
|
||
|
|
// Equal keys keep input order - matches haxe Array.sort semantics.
|
||
|
|
Radix.sortCopyKeyed(meshes, keys, meshesBuf, keysBuf);
|
||
|
|
|
||
|
|
// In-place MSD sort on the same (element, keys) arrays.
|
||
|
|
// No scratch buffer needed, but NOT stable - equal keys may reorder.
|
||
|
|
Radix.sortKeyed(meshes, keys);
|
||
|
|
|
||
|
|
// Or let the sorter build keys from an extractor
|
||
|
|
Radix.sort(meshes, function(m) {
|
||
|
|
return (m.depthRead ? 0x80000000 : 0) | (FPHelper.floatToI32(m.cameraDistance) >>> 1);
|
||
|
|
});
|
||
|
|
```
