Class OutputFixingParser<T>

constructor

• new OutputFixingParser<T>(__namedParameters): OutputFixingParser<T>

• Type Parameters

  • T

  Parameters

  • __namedParameters: {
        parser: BaseOutputParser<T>;
        retryChain: LLMChain<string, LLMType>;
    }

    • parser: BaseOutputParser<T>

    • retryChain: LLMChain<string, LLMType>

  Returns OutputFixingParser<T>

parser

retryChain

getFormatInstructions

• getFormatInstructions(): string

• Method to get the format instructions for the parser.

  Returns string

  The format instructions for the parser.

parse

• parse(completion, callbacks?): Promise<T>

• Method to parse the completion using the parser. If the initial parsing fails, it uses the retryChain to attempt to fix the output and retry the parsing process.

  Parameters

  • completion: string

    The completion to be parsed.

  • Optional callbacks: Callbacks

    Optional callbacks to be used during parsing.

  Returns Promise<T>

  The parsed output.

Static fromLLM

• fromLLM<T>(llm, parser, fields?): OutputFixingParser<T>

• Static method to create a new instance of OutputFixingParser using a given language model, parser, and optional fields.

  Type Parameters

  • T

  Parameters

  • llm: BaseLanguageModel<any, BaseLanguageModelCallOptions>

    The language model to be used.

  • parser: BaseOutputParser<T>

    The parser to be used.

  • Optional fields: {
        prompt?: BasePromptTemplate<any, BasePromptValue, any>;
    }

    Optional fields which may contain a prompt.

    • Optional prompt?: BasePromptTemplate<any, BasePromptValue, any>

  Returns OutputFixingParser<T>

  A new instance of OutputFixingParser.
