Examples with Message io.protostuff.Message used on opensource projects

Example 1 with Message

use of io.protostuff.Message in project datawave by NationalSecurityAgency.

the class ProtostuffMessageBodyWriter method writeTo.

@SuppressWarnings("unchecked")
@Override
public void writeTo(Object message, Class<?> clazz, Type type, Annotation[] annotations, MediaType media, MultivaluedMap<String, Object> httpHeaders, OutputStream out) throws IOException, WebApplicationException {
    // TODO: Figure out a method to add the proto file location in the response headers.
    // This map must be mofified before any data is written to out,
    // since at that time the response headers will be flushed.
    Schema<Object> schema = null;
    if (message instanceof Message) {
        Message<Object> msg = (Message<Object>) message;
        schema = msg.cachedSchema();
    } else {
