Constructors

constructor

new Embeddings(params): Embeddings
Parameters
- params: AsyncCallerParams
Returns Embeddings
- Defined in langchain-core/src/embeddings.ts:39

Properties

caller

caller: AsyncCaller

The async caller should be used by subclasses to make any async calls, which will thus benefit from the concurrency and retry logic.

Methods

`Abstract` embedDocuments

embedDocuments(documents): Promise<number[][]>
An abstract method that takes an array of documents as input and returns a promise that resolves to an array of vectors for each document.
Parameters
- documents: string[]
  
  An array of documents to be embedded.
Returns Promise<number[][]>
A promise that resolves to an array of vectors for each document.
Implementation of EmbeddingsInterface.embedDocuments
- Defined in langchain-core/src/embeddings.ts:50

`Abstract` embedQuery

embedQuery(document): Promise<number[]>
An abstract method that takes a single document as input and returns a promise that resolves to a vector for the query document.
Parameters
- document: string
  
  A single document to be embedded.
Returns Promise<number[]>
A promise that resolves to a vector for the query document.
