FutureCallbacks

object FutureCallbacks

Java-friendly adapters for the engine's callback interfaces.

Every engine callback is an interface with a single suspend fun call(...), which no Java lambda or class can implement. Each factory pairs an engine callback with a CompletableFuture -returning functional interface and awaits it -- the same async idiom as the BaseFuture* SPI bases, with no blocking dispatcher. The sealed CallbackChoice return is built and read via Choices.

Functions

fun afterAgent(callback: FutureAfterAgentCallback): AfterAgentCallback

Runs after an agent.

fun afterModel(callback: FutureAfterModelCallback): AfterModelCallback

Runs after each model call; may rewrite the response.

fun afterTool(callback: FutureAfterToolCallback): AfterToolCallback

Runs after each tool call; may rewrite the result.

fun beforeAgent(callback: FutureBeforeAgentCallback): BeforeAgentCallback

Runs before an agent; return Choices.proceed to continue or Choices.breakWith to skip.

fun beforeModel(callback: FutureBeforeModelCallback): BeforeModelCallback

Runs before each model call; may rewrite the request or short-circuit with a response.

fun beforeTool(callback: FutureBeforeToolCallback): BeforeToolCallback

Runs before each tool call; may rewrite the arguments or short-circuit with a result.

fun onModelError(callback: FutureOnModelErrorCallback): OnModelErrorCallback

Runs when a model call throws; may swallow the error by returning a response.

fun onToolError(callback: FutureOnToolErrorCallback): OnToolErrorCallback

Runs when a tool throws; may swallow the error by returning a result.
