Class SurfaceSerializer

java.lang.Object

com.codename1.surfaces.SurfaceSerializer

public final class SurfaceSerializer
extends Object

Serializes surface descriptors to the canonical wire format shared by every port: a compact JSON document plus PNG blobs named by content hash. This class is an internal seam between the core API and the platform bridges -- it is public only because ports live in separate artifacts; apps never call it.

The wire format is versioned ("v": 1) and deterministic: node maps preserve build order, state maps are emitted with sorted keys, timeline entries are sorted ascending by date and image names derive from a hash of the PNG bytes (identical art always gets the same name).
