Enclosing class:

WLongArrayList

public static class WLongArrayList.WReusableLongArrayList
extends WLongArrayList

Variant of WLongArrayList 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)
