An implementation of MessagePack for Java ME.
ByteArrayOutputStream out = new ByteArrayOutputStream();
Packer packer = new MessagePack().createPacker(out);
packer.writeArrayBegin(4);
packer.write(1);
packer.write("Hello world");
packer.write(true);
packer.write(1.2f);
packer.writeArrayEnd();
packer.flush();
byte[] bytes = out.toByteArray();
ByteArrayInputStream in = new ByteArrayInputStream(bytes);
Unpacker unpacker = new MessagePack().createUnpacker(in);
unpacker.readArrayBegin();
int a = unpacker.readInt();
String b = unpacker.readString();
boolean c = unpacker.readBool();
float d = unpacker.readFloat();
unpacker.readArrayEnd();
unpacker.close();
