Constructor Details

ChromaEmbeddingStore

public ChromaEmbeddingStore(ChromaEmbeddingStore.Builder builder)

Initializes a new instance of ChromaEmbeddingStore with the specified parameters.

Parameters:

builder - The builder instance of ChromaEmbeddingStore.Builder.

ChromaEmbeddingStore

@Deprecated(since="1.7.0-beta13",
            forRemoval=true)
public ChromaEmbeddingStore(String baseUrl,
 String collectionName,
 Duration timeout,
 boolean logRequests,
 boolean logResponses)

Deprecated, for removal: This API element is subject to removal in a future version.

Only works with the V1 API, use the ChromaEmbeddingStore(Builder) constructor instead.

Initializes a new instance of ChromaEmbeddingStore (V1 API) with the specified parameters.

Parameters:

baseUrl - The base URL of the Chroma service.

collectionName - The name of the collection in the Chroma service. If not specified, "default" will be used.

timeout - The timeout duration for the Chroma client. If not specified, 5 seconds will be used.

logRequests - If true, requests to the Chroma service are logged.

logResponses - If true, responses from the Chroma service are logged.
