Collectors

cajeta.collection.Collectors — standard Collector factories. Each method returns a Collector that Stream’s collect terminal can consume. The factories are method-level templated, so each call site monomorphizes per T, and every collector ships a combiner alongside the (seed, accumulator) pair so .parallel().collect(...) can merge per-worker partials.

// Stream -> collect -> owned list:
int32[] data = { 3, 1, 2 };
ArrayList<int32> xs = (heap ArrayStream<int32>(data, 3))
    .collect(Collectors.toList<int32>());

Methods

Signature
static #Collector<T, ArrayList<T>> toList<T>()Collect every element into a fresh ArrayList<T>; the combiner appends right onto left via appendAll
