Enclosing class:

WIntArrayList

public static class WIntArrayList.WReusableIntArrayList
extends WIntArrayList

Variant of WIntArrayList that doesn't reallocate smaller backing array on consecutive readFields/readElements calls, and so is suitable for reusable use. (and backing array will only grow on readFields/readElements calls)
