Fork from http://code.google.com/p/protobuf-java-format/
Provide serialization and de-serialization of different formats based on Google’s protobuf Message. Enables overriding the default (byte array) output to text based formats such as XML, JSON and HTML.
##Example For XML output, use XmlFormat
Message someProto = SomeProto.getDefaultInstance();
String xmlFormat = XmlFormat.printToString(someProto);For XML input, use XmlFormat
Message.Builder builder = SomeProto.newBuilder();
String xmlFormat = _load xml document from a source_;
XmlFormat.merge(xmlFormat, builder);For Json output, use JsonFormat
Message someProto = SomeProto.getDefaultInstance();
String jsonFormat = JsonFormat.printToString(someProto);For Json input, use JsonFormat
Message.Builder builder = SomeProto.newBuilder();
String jsonFormat = _load json document from a source_;
JsonFormat.merge(jsonFormat, builder);For HTML output, use HtmlFormat
Message someProto = SomeProto.getDefaultInstance();
String htmlFormat = HtmlFormat.printToString(someProto);
