    • build

      public StateGraph<AgentExecutor.State> build() throws GraphStateException
      Builds and returns a StateGraph with the specified configuration. Initializes the stateSerializer if it's null. Then, constructs a new StateGraph object using the provided schema and serializer, adds an initial edge from the START node to "agent", and then proceeds to add nodes for "agent" and "action". It also sets up conditional edges from the "agent" node based on whether or not to continue.
      Returns:
      A configured StateGraph object.
      Throws:
      GraphStateException - If there is an issue with building the graph state.
