    Constructors

    • Parameters

      • Optionalkwargs: SerializedFields
      • ..._args: never[]

      Returns RecordManager

    Properties

    lc_kwargs: SerializedFields
    lc_namespace: string[] = ...

    A path to the module that contains the class, eg. ["langchain", "llms"] Usually should be the same as the entrypoint the class is exported from.

    lc_serializable: boolean = false

    Accessors

    • get lc_aliases(): undefined | { [key: string]: string }

      A map of aliases for constructor args. Keys are the attribute names, e.g. "foo". Values are the alias that will replace the key in serialization. This is used to eg. make argument names match Python.

      Returns undefined | { [key: string]: string }

    • get lc_attributes(): undefined | SerializedFields

      A map of additional attributes to merge with constructor args. Keys are the attribute names, e.g. "foo". Values are the attribute values, which will be serialized. These attributes need to be accepted by the constructor as arguments.

      Returns undefined | SerializedFields

    • get lc_id(): string[]

      The final serialized identifier for the module.

      Returns string[]

    • get lc_secrets(): undefined | { [key: string]: string }

      A map of secrets, which will be omitted from serialization. Keys are paths to the secret in constructor args, e.g. "foo.bar.baz". Values are the secret ids, which will be used when deserializing.

      Returns undefined | { [key: string]: string }

    • get lc_serializable_keys(): undefined | string[]

      A manual list of keys that should be serialized. If not overridden, all fields passed into the constructor will be serialized.

      Returns undefined | string[]

    Methods

    • Creates schema in the record manager.

      Returns Promise<void>

      Promise

    • Deletes keys from the record manager.

      Parameters

      • keys: string[]

        List of keys to delete

      Returns Promise<void>

    • Checks if keys exist in the record manager.

      Parameters

      • keys: string[]

        List of keys to check

      Returns Promise<boolean[]>

      List of booleans indicating if key exists in same order as provided keys

    • Returns current time from the record manager.

      Returns Promise<number>

      Current time

    • Lists keys from the record manager.

      Parameters

      Returns Promise<string[]>

      List of keys

    • Updates keys in the record manager.

      Parameters

      • keys: string[]

        List of keys to update

      • OptionalupdateOptions: UpdateOptions

      Returns Promise<void>

      Promise

      Error if timeAtLeast is provided and current time is less than timeAtLeast

      Error if number of keys does not match number of groupIds

    • The name of the serializable. Override to provide an alias or to preserve the serialized module name in minified environments.

      Implemented as a static method to support loading logic.

      Returns string
