                                Method SummaryModifier and Type Method Description abstract TvisitOptions(ToolChoiceOptions options)Controls which (if any) tool is called by the model. abstract TvisitAllowed(ToolChoiceAllowed allowed)Constrains the tools available to the model to a pre-defined set. abstract TvisitTypes(ToolChoiceTypes types)Indicates that the model should use a built-in tool to generate a response. abstract TvisitFunction(ToolChoiceFunction function)Use this option to force the model to call a specific function. abstract TvisitMcp(ToolChoiceMcp mcp)Use this option to force the model to call a specific tool on a remote MCP server. abstract TvisitCustom(ToolChoiceCustom custom)Use this option to force the model to call a specific custom tool. Tunknown(JsonValue json)Maps an unknown variant of ToolChoice to a value of type T. -

                                        visitOptionsabstract T visitOptions(ToolChoiceOptions options) Controls which (if any) tool is called by the model. nonemeans the model will not call any tool and instead generates a message.automeans the model can pick between generating a message or calling one or more tools.requiredmeans the model must call one or more tools.

                                        visitTypesabstract T visitTypes(ToolChoiceTypes types) Indicates that the model should use a built-in tool to generate a response. Learn more about built-in tools.

                                        visitFunctionabstract T visitFunction(ToolChoiceFunction function) Use this option to force the model to call a specific function.

                                        visitMcpabstract T visitMcp(ToolChoiceMcp mcp) Use this option to force the model to call a specific tool on a remote MCP server.

                                        unknownT unknown(JsonValue json) Maps an unknown variant of ToolChoice to a value of type T. An instance of ToolChoice can contain an unknown variant if it was deserialized from data that doesn't match any known variant. For example, if the SDK is on an older version than the API, then the API may respond with new variants that the SDK is unaware of.
