Class TeaVmJson

java.lang.Object
net.sourceforge.plantuml.teavm.headless.TeaVmJson
public final class TeaVmJson extends Object
Small TeaVM helper to build JSON results from Java without hand-rolling the escaping.

Instead of assembling JSON text character by character (and getting quoting, newlines and control-character escapes right by hand), the headless entry point builds a native JS object/array through these @JSBody helpers and serializes it with the platform's JSON.stringify. This mirrors the stringify helper already used by TeaVmScriptLoader.

All methods are TeaVM-only (they compile to plain JS); they are not meant to be called from a normal JVM.
