Enclosing class:

WFloatArrayList

public static class WFloatArrayList.WReusableFloatArrayList
extends WFloatArrayList

Variant of WFloatArrayList 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)
