Class ChatConversationalAgentOutputParser

Class that represents an output parser for the ChatConversationalAgent class. It extends the AgentActionOutputParser class and provides methods for parsing the output of the MRKL chain into agent actions.

Hierarchy

Constructors

Methods

  • Returns the format instructions as a string. If the 'raw' option is true, returns the raw FORMAT_INSTRUCTIONS.

    Returns string

    Format instructions as a string.

  • Calls the parser with a given input and optional configuration options. If the input is a string, it creates a generation with the input as text and calls parseResult. If the input is a BaseMessage, it creates a generation with the input as a message and the content of the input as text, and then calls parseResult.

    Parameters

    • input: string | BaseMessage

      The input to the parser, which can be a string or a BaseMessage.

    • Optional options: BaseCallbackConfig

      Optional configuration options.

    Returns Promise<AgentAction | AgentFinish>

    A promise of the parsed output.

  • Parses the given text into an AgentAction or AgentFinish object. If an output fixing parser is defined, uses it to parse the text.

    Parameters

    • text: string

      Text to parse.

    Returns Promise<AgentAction | AgentFinish>

    Promise that resolves to an AgentAction or AgentFinish object.

  • Create a new runnable sequence that runs each individual runnable in series, piping the output of one runnable into another runnable or runnable-like.

    Type Parameters

    • NewRunOutput

    Parameters

    Returns RunnableSequence<string | BaseMessage, Exclude<NewRunOutput, Error>>

    A new runnable sequence.

  • Stream all output from a runnable, as reported to the callback system. This includes all inner runs of LLMs, Retrievers, Tools, etc. Output is streamed as Log objects, which include a list of jsonpatch ops that describe how the state of the run has changed in each step, and the final state of the run. The jsonpatch ops can be applied in order to construct state.

    Parameters

    • input: string | BaseMessage
    • Optional options: Partial<BaseCallbackConfig>
    • Optional streamOptions: Omit<LogStreamCallbackHandlerInput, "autoClose">

    Returns AsyncGenerator<RunLogPatch, any, unknown>

  • Default implementation of transform, which buffers input and then calls stream. Subclasses should override this method if they can start producing output while input is still being generated.

    Parameters

    Returns AsyncGenerator<AgentAction | AgentFinish, any, unknown>

  • Bind lifecycle listeners to a Runnable, returning a new Runnable. The Run object contains information about the run, including its id, type, input, output, error, startTime, endTime, and any tags or metadata added to the run.

    Parameters

    • params: {
          onEnd?: ((run, config?) => void | Promise<void>);
          onError?: ((run, config?) => void | Promise<void>);
          onStart?: ((run, config?) => void | Promise<void>);
      }

      The object containing the callback functions.

      • Optional onEnd?: ((run, config?) => void | Promise<void>)
          • (run, config?): void | Promise<void>
          • Called after the runnable finishes running, with the Run object.

            Parameters

            Returns void | Promise<void>

      • Optional onError?: ((run, config?) => void | Promise<void>)
          • (run, config?): void | Promise<void>
          • Called if the runnable throws an error, with the Run object.

            Parameters

            Returns void | Promise<void>

      • Optional onStart?: ((run, config?) => void | Promise<void>)
          • (run, config?): void | Promise<void>
          • Called before the runnable starts running, with the Run object.

            Parameters

            Returns void | Promise<void>

    Returns Runnable<string | BaseMessage, AgentAction | AgentFinish, BaseCallbackConfig>
