Examples of com.hazelcast.nio.Packet

com.hazelcast.nio.Packet
A Packet is a piece of data send over the line.


        UsernamePasswordCredentials credentials = new UsernamePasswordCredentials("test", "pass");
        ClientPrincipal principal = new ClientPrincipal("uuid", "uuid2");
        Data data = ss.toData(new AuthenticationRequest(credentials, principal));


        Packet packet = new Packet(data, ss.getPortableContext());
        ByteBuffer buffer = ByteBuffer.allocate(1024);
        assertTrue(packet.writeTo(buffer));


        SerializationService ss2 = createSerializationService(1);


        buffer.flip();
        packet = new Packet(ss2.getPortableContext());
        assertTrue(packet.readFrom(buffer));


        AuthenticationRequest request = ss2.toObject(packet.getData());
