onLLMStreamingFrameReceived

fun onLLMStreamingFrameReceived(handler: suspend (eventContext: LLMStreamingFrameReceivedContext) -> Unit)(source)

Registers a handler to be invoked when stream frames are received during streaming.

This handler is called for each stream frame as it arrives from the language model, enabling real-time processing, monitoring, or aggregation of streaming content.

Parameters

handler

The handler function that receives a LLMStreamingFrameReceivedContext containing the run ID and the stream frame with partial response data.

Example:

onLLMStreamingFrameReceived { eventContext ->
    when (val frame = eventContext.streamFrame) {
        is StreamFrame.Append -> processText(frame.text)
        is StreamFrame.ToolCall -> processTool(frame)
    }
}
