public final class Base64VLQ
extends Object

We encode our variable length numbers as base64 encoded strings with the least significant digit coming first. Each base64 digit encodes a 5-bit value (0-31) and a continuation bit. Signed values can be represented by using the least significant bit of the value as the sign bit.
