`Abstract` lc_namespace

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.

Methods

`Abstract` mdelete

mdelete(keys): Promise<void>
Abstract method to delete multiple keys.
Parameters
- keys: K[]
  
  An array of keys to delete.
Returns Promise<void>
- A Promise that resolves when the operation is complete.
Implementation of BaseStoreInterface.mdelete
- Defined in langchain/src/schema/storage.ts:60

`Abstract` mget

mget(keys): Promise<(undefined | V)[]>
Abstract method to get multiple values for a set of keys.
Parameters
- keys: K[]
  
  An array of keys.
Returns Promise<(undefined | V)[]>
- A Promise that resolves with array of values or undefined if key not found.
Implementation of BaseStoreInterface.mget
- Defined in langchain/src/schema/storage.ts:46

`Abstract` mset

mset(keyValuePairs): Promise<void>
Abstract method to set a value for multiple keys.
Parameters
- keyValuePairs: [K, V][]
  
  An array of key-value pairs.
Returns Promise<void>
- A Promise that resolves when the operation is complete.
Implementation of BaseStoreInterface.mset
- Defined in langchain/src/schema/storage.ts:53

toJSON

toJSON(): Serialized
Returns Serialized
Inherited from Serializable.toJSON
- Defined in langchain/src/load/serializable.ts:147

toJSONNotImplemented

toJSONNotImplemented(): SerializedNotImplemented
Returns SerializedNotImplemented
Inherited from Serializable.toJSONNotImplemented
- Defined in langchain/src/load/serializable.ts:221

`Abstract` yieldKeys

yieldKeys(prefix?): AsyncGenerator<string | K, any, unknown>
Abstract method to yield keys optionally based on a prefix.
Parameters
- Optional prefix: string
  
  Optional prefix to filter keys.
Returns AsyncGenerator<string | K, any, unknown>
- An asynchronous generator that yields keys on iteration.
Implementation of BaseStoreInterface.yieldKeys
- Defined in langchain/src/schema/storage.ts:67
