Enclosing class:

WByteArrayList

public static class WByteArrayList.WReusableByteArrayList
extends WByteArrayList

Variant of WByteArrayList 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)
