Class JsonOut

Object

gudusoft.gsqlparser.pp.score.json.JsonOut

public final class JsonOut
extends Object

Minimal, dependency-free JSON writer with deterministic output.

Handles Map (insertion order preserved), Collection, arrays, String, Number, Boolean, Enum (as its lower-case name) and null. Doubles are written with at most three decimals and no exponent so two runs over the same input produce byte-identical text.

Package-private on purpose: the JSON contract is owned by ScoreReport; nothing else should serialise ad hoc.
