Uses of DecisionAgentBuilder in dev.langchain4j.agentic

Methods in dev.langchain4j.agentic that return DecisionAgentBuilder

Modifier and Type	Method	Description
static <T> DecisionAgentBuilder<T>	AgenticServices.decisionAgentBuilder(Class<T> agentServiceClass)	Creates a builder for a decision agent: an agent whose implementation is a single call to a DecisionModel instead of a chat model.
default DecisionAgentBuilder<T>	AgenticServices.DeclarativeAgentCreationContext.decisionAgentBuilder()	The builder of the decision agent being created, or null when it is an AI agent.
DecisionAgentBuilder<T>	AgenticServices.DefaultDeclarativeDecisionAgentCreationContext.decisionAgentBuilder()

Constructors in dev.langchain4j.agentic with parameters of type DecisionAgentBuilder

Modifier	Constructor	Description
	DefaultDeclarativeDecisionAgentCreationContext(Class<T> agentServiceClass, DecisionAgentBuilder<T> decisionAgentBuilder)

Uses of DecisionAgentBuilder in dev.langchain4j.agentic.agent

Methods in dev.langchain4j.agentic.agent that return DecisionAgentBuilder

Modifier and Type	Method	Description
DecisionAgentBuilder<T>	DecisionAgentBuilder.activationCondition(String description, Predicate<AgenticScope> activationCondition)	Sets the condition under which this agent runs when it is invoked as a subagent of an agentic system, with a human-readable description used in logs, listeners and reports.
DecisionAgentBuilder<T>	DecisionAgentBuilder.activationCondition(Predicate<AgenticScope> activationCondition)	Sets the condition under which this agent runs when it is invoked as a subagent of an agentic system.
DecisionAgentBuilder<T>	DecisionAgentBuilder.agentInstanceFactory(Function<InternalAgent, Object> factory)
DecisionAgentBuilder<T>	DecisionAgentBuilder.async(boolean async)	Controls whether this agent executes asynchronously within an agentic system: the decision call then runs on the executor used for every asynchronous agent, and the agents reading its output wait for it.
DecisionAgentBuilder<T>	DecisionAgentBuilder.decisionModel(DecisionModel decisionModel)	Sets the DecisionModel answering the question(s) of this agent.
DecisionAgentBuilder<T>	DecisionAgentBuilder.decisionModelProvider(Function<AgenticScope, DecisionModel> decisionModelProvider)	Sets a provider that resolves the DecisionModel from the AgenticScope before each invocation, for example to pick a model depending on the state of the scope.
DecisionAgentBuilder<T>	DecisionAgentBuilder.description(String description)	Sets the description of this agent, overriding the one of @Agent.
DecisionAgentBuilder<T>	DecisionAgentBuilder.listener(AgentListener agentListener)	Adds a listener of the invocations of this agent, composed with the ones already registered.
DecisionAgentBuilder<T>	DecisionAgentBuilder.name(String name)	Sets the name of this agent, overriding the one of @Agent or the method name.
DecisionAgentBuilder<T>	DecisionAgentBuilder.optional(boolean optional)	Controls whether this agent is optional: when it is, it is skipped instead of failing when one of its arguments is missing from the AgenticScope.
DecisionAgentBuilder<T>	DecisionAgentBuilder.outputKey(Class<? extends TypedKey<?>> outputKey)	Sets the output key using a TypedKey class for type-safe scope access.
DecisionAgentBuilder<T>	DecisionAgentBuilder.outputKey(String outputKey)	Sets the key of the AgenticScope where the answer of this agent is written, overriding the one of @Agent.
DecisionAgentBuilder<T>	DecisionAgentBuilder.requestParameters(DecisionRequestParameters requestParameters)	Sets the parameters of every decision request of this agent, such as the model name, overriding the defaults of the decision model.
DecisionAgentBuilder<T>	DecisionAgentBuilder.threshold(double threshold)	Sets a fixed threshold for the boolean answers of this agent: the answer is true when the probability of "yes" is at least the threshold.
DecisionAgentBuilder<T>	DecisionAgentBuilder.thresholdProvider(ThresholdProvider thresholdProvider)	Sets the provider of the threshold of the boolean answers of this agent: the answer is true when the probability of "yes" is at least the threshold.
static <T> DecisionAgentBuilder<T>	DecisionAgentBuilder.withoutDeclarativeConfiguration(Class<T> agentServiceClass)

Uses of DecisionAgentBuilder in dev.langchain4j.agentic.declarative

Methods in dev.langchain4j.agentic.declarative with parameters of type DecisionAgentBuilder

Modifier and Type	Method	Description
static void	DeclarativeUtil.configureDecisionAgent(Class<?> agentType, DecisionAgentBuilder<?> builder)
static void	DeclarativeUtil.configureDecisionAgent(Class<?> agentType, DecisionAgentBuilder<?> builder, AgenticServices.AgentConfigurator agentConfigurator)	Applies the declarative configuration of the given decision agent interface to its builder: the DecisionModelSupplier, the DecisionThresholdSupplier, the AgentListenerSupplier, the ActivationCondition and the agent configurator.
