Method Summary

Modifier and Type	Method	Description
static Response<Embedding>	withListeners(EmbeddingModel model, TextSegment textSegment, Supplier<Response<Embedding>> operation)	Single-embedding overload of withListeners(EmbeddingModel, List, Supplier), for providers that override EmbeddingModel.embed(TextSegment) with a dedicated API call.
static Response<List<Embedding>>	withListeners(EmbeddingModel model, List<TextSegment> textSegments, Supplier<Response<List<Embedding>>> operation)	Notifies the model's listeners around a raw batch embedding operation that does not itself route through EmbeddingModel.embed(EmbeddingRequest).

Method Details

withListeners

public static Response<List<Embedding>> withListeners(EmbeddingModel model,
 List<TextSegment> textSegments,
 Supplier<Response<List<Embedding>>> operation)

Notifies the model's listeners around a raw batch embedding operation that does not itself route through EmbeddingModel.embed(EmbeddingRequest).

A provider that overrides EmbeddingModel.embedAll(List) to apply batch-specific behavior the request/response API does not carry (for example a document title from TextSegment metadata) can wrap the actual API call with this method so that listeners are still notified consistently. Callers must ensure the wrapped operation does not itself dispatch listeners, otherwise listeners are notified twice.

Parameters:

model - the embedding model whose listeners are notified.

textSegments - the segments being embedded.

operation - the raw embedding call.

Returns:

the result of operation.

withListeners

public static Response<Embedding> withListeners(EmbeddingModel model,
 TextSegment textSegment,
 Supplier<Response<Embedding>> operation)

Single-embedding overload of withListeners(EmbeddingModel, List, Supplier), for providers that override EmbeddingModel.embed(TextSegment) with a dedicated API call.

Parameters:

model - the embedding model whose listeners are notified.

textSegment - the segment being embedded.

operation - the raw embedding call.

Returns:

the result of operation.
