Method Details

embedAll

public Response<List<Embedding>> embedAll(List<TextSegment> textSegments)

Description copied from interface: EmbeddingModel

Embeds the text content of a list of TextSegments.

This is a convenience method over EmbeddingModel.embed(EmbeddingRequest), so listeners are notified and the model's default per-call parameters are applied here too. A provider implements its embedding logic by overriding EmbeddingModel.doEmbed(EmbeddingRequest) (preferred); it may still override this method for batch-specific behavior that the request/response API does not carry (for example applying a document title from TextSegment metadata).

Parameters:

textSegments - the text segments to embed.

Returns:

the embeddings.
