Usage

From source file:de.terrestris.shogun.serializer.SimpleUserSerializer.java

@Override
public void serialize(User value, JsonGenerator jgen, SerializerProvider provider)
        throws IOException, JsonProcessingException {
    jgen.writeNumber(value.getId());

    // Also serialize the name of the user into a field "ownerName"
    // TODO We shouldn't assume that we always are serializing
    //      an "owner" (hence "ownerName" might be not very good decision)
    // TODO In case we have multiple User.class entities that are serialized
    //      this might lead to an illegal (?) JSON, as duplicate keys might
    //      be produced. I do not know how all parsers deal with this.
    //      "The names within an object SHOULD be unique."
    //      http://www.ietf.org/rfc/rfc4627.txt
    String ownerName = null;/*from w  w w.j  ava  2s  .  c  om*/
    if (value.getUser_firstname() != null) {
        ownerName = value.getUser_firstname();
    }

            ownerName = "";
        } else {
            ownerName += " ";
        }
