Enclosing class:

WBooleanArrayList

public static class WBooleanArrayList.WReusableBooleanArrayList
extends WBooleanArrayList

Variant of WBooleanArrayList 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)
