Class ProtoJsonUtils

java.lang.Object
org.a2aproject.sdk.grpc.utils.ProtoJsonUtils
public final class ProtoJsonUtils extends Object
Protobuf-to-JSON serialization without HTML escaping.

JsonFormat.printer() delegates to Gson's JsonWriter which HTML-escapes <, >, and & by default. This utility removes those escape sequences via HtmlEscapeUtils.removeHtmlEscaping(String).
