public @interface DecisionService

Registers a LangChain4j decision service: an interface whose methods are answered by a DecisionModel, created with DecisionServices.

The return type of a method determines the question: a boolean or described enum, a Choice, a Scale or an object of those, set with Decide.

The service uses the DecisionModel and ThresholdProvider beans named after the service, otherwise the default ones.

Since:
