public class VncTinyVector
extends VncVector

An immutable vector optimized for keeping 1 to 4 values. Returns a VncVector if the list grows beyond its max length.

Most of the vectors in a typical Venice application have less than 5 items. This optimized implementation for an immutable tiny vector is much faster than a VAVR persistent vector that can hold an arbitrary number of items.
