Why are these fields private?

[sammyjava]

I cannot access these fields because they are private in your package. But there are no getters, either. Is this a mistake? Or is there some other way I am supposed to access an Embedding? Right now it seems I need to make them public, or add getters, to be able to use them in my package.

/home/shokin/java/pure-gas/openai-pinecone/src/main/java/org/puregas/openai/EmbeddingTest.java:33: error: object is not public in Embedding; cannot be accessed from outside package
            System.out.println(embedding.object);
                                        ^
/home/shokin/java/pure-gas/openai-pinecone/src/main/java/org/puregas/openai/EmbeddingTest.java:34: error: index is not public in Embedding; cannot be accessed from outside package
            System.out.println(embedding.index);
                                        ^
/home/shokin/java/pure-gas/openai-pinecone/src/main/java/org/puregas/openai/EmbeddingTest.java:35: error: embedding is not public in Embedding; cannot be accessed from outside package
            System.out.println(embedding.embedding);

I have noticed that Embedding.toString() is public and returns a string that I can parse, but that is hugely error-prone and clearly not optimal.

Do you have lombok.jar installed in your dev environment? It should auto-magically generate all getters and setters.

Embedding.java does have object available.

https://github.com/TheoKanning/openai-java/blob/900e13bbda6c38adababebce8418f9aed0484d61/api/src/main/java/com/theokanning/openai/embedding/Embedding.java

If you have lombok installed and have cleaned and recompiled all the classes, you might have to Change the object serialized name as sometimes java reserved names conflict w/ variable names. Right before line 18 in Embedding.java....

    @SerializedName(value = "object")

Okay, I've never used lombok so I was a bit mystified by this. I thought I could just include your packages, but realize your stuff is built under the lombok umbrella. That will be a bit of research on my part, I'm just using a text editor and the gradle compile. I didn't think an IDE was required. Could you document how lombok is required and what one needs to do to use it? Or perhaps a link? Thanks!

GOT IT! These gradle packages allowed me to use Embedding.getIndex(), which of course is not present in the Javadoc. I've learned something, thanks for the tip.

Well in theory it should just work!

Try calling:

String e = embedding.getObject();
Integer i = embedding.getIndex();
List<Double> le = embedding.getEmbedding();

Make sure you have lombok.java in your java classpath. In the data classes there are two things:

import lombok.Data;

@Data 
public class ... {
}

compiling it w/ gradle or not, it should just work. You should be able to declare:

List<Embedding> embeddings = service.createEmbeddings(embeddingRequest).getData();
for (Embedding e : embeddings) {
  System.out.println(e.getObject());
}

Lombok takes any declared variables and the data annotation will create the constructors, mappings, and getters/setters, equals, and toString with the default behaviors. Any of these can be overridden.
