Class ValueArrays

public final class ValueArrays
extends Object

Defensive-copy helpers for immutable result types.

Result and report classes copy their array and collection arguments once on construction and never hand out the internal copy. Callers read single elements through indexed accessors (no allocation) and ask for a copy only when they need the whole array. Collections are copied with List.copyOf or an unmodifiable ordered copy at the call site.
