Get Signature

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

Defined in: node_modules/@langchain/core/dist/callbacks/base.d.ts:164 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;
};

Defined in: node_modules/@langchain/core/dist/callbacks/base.d.ts:161 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 | { [key: string]: string; }

};

Defined in: node_modules/@langchain/core/dist/callbacks/base.d.ts:158 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; }

Inherited from

(
  _BaseCallbackHandler as typeof import("@langchain/core/callbacks/base").BaseCallbackHandler
