langchain_core.stores.InMemoryBaseStore¶
- class langchain_core.stores.InMemoryBaseStore[source]¶
In-memory implementation of the BaseStore using a dictionary.
Initialize an empty store.
Methods
__init__()Initialize an empty store.
amdelete(keys)Async delete the given keys and their associated values.
amget(keys)Async get the values associated with the given keys.
amset(key_value_pairs)Async set the values for the given keys.
ayield_keys([prefix])Async get an async iterator over keys that match the given prefix.
mdelete(keys)Delete the given keys and their associated values.
mget(keys)Get the values associated with the given keys.
mset(key_value_pairs)Set the values for the given keys.
yield_keys([prefix])Get an iterator over keys that match the given prefix.
- async amdelete(keys: Sequence[str]) None[source]¶
Async delete the given keys and their associated values.
- Parameters
keys (Sequence[str]) – A sequence of keys to delete.
- Return type
None
- async amget(keys: Sequence[str]) List[Optional[V]][source]¶
Async get the values associated with the given keys.
- Parameters
keys (Sequence[str]) – A sequence of keys.
- Returns
A sequence of optional values associated with the keys. If a key is not found, the corresponding value will be None.
- Return type
List[Optional[V]]
- async amset(key_value_pairs: Sequence[Tuple[str, V]]) None[source]¶
Async set the values for the given keys.
- Parameters
key_value_pairs (Sequence[Tuple[str, V]]) – A sequence of key-value pairs.
- Returns
None
- Return type
None
- async ayield_keys(prefix: Optional[str] = None) AsyncIterator[str][source]¶
Async get an async iterator over keys that match the given prefix.
- Parameters
prefix (str, optional) – The prefix to match. Defaults to None.
- Yields
AsyncIterator[str] – An async iterator over keys that match the given prefix.
- Return type
AsyncIterator[str]
- mdelete(keys: Sequence[str]) None[source]¶
Delete the given keys and their associated values.
- Parameters
keys (Sequence[str]) – A sequence of keys to delete.
- Return type
None
- mget(keys: Sequence[str]) List[Optional[V]][source]¶
Get the values associated with the given keys.
- Parameters
keys (Sequence[str]) – A sequence of keys.
- Returns
A sequence of optional values associated with the keys. If a key is not found, the corresponding value will be None.
- Return type
List[Optional[V]]
