In-memory store implementation for testing and single-process use.

Thread-safe via mutex. Items are stored in a std::map keyed by a composite string of namespace + key.

delete_item()

void neograph::graph::InMemoryStore::delete_item ( const Namespace &  ns, const std::string &  key  )

overridevirtual

Delete a single item.

Parameters

ns	Namespace path.
key	Item key to delete.

Implements neograph::graph::Store.

get()

std::optional< StoreItem > neograph::graph::InMemoryStore::get ( const Namespace &  ns, const std::string &  key  ) const

overridevirtual

Retrieve a single item.

Parameters

ns	Namespace path.
key	Item key.

Returns

The item, or std::nullopt if not found.

Implements neograph::graph::Store.

list_namespaces()

std::vector< Namespace > neograph::graph::InMemoryStore::list_namespaces ( const Namespace &  prefix = {} ) const

overridevirtual

List all namespaces under a prefix.

Parameters

prefix

Namespace prefix to filter by (empty = list all).

Returns

Vector of unique Namespace paths.

Implements neograph::graph::Store.

put()

void neograph::graph::InMemoryStore::put ( const Namespace &  ns, const std::string &  key, const json &  value  )

overridevirtual

Store a value (create or update).

Parameters

ns	Namespace path for the item.
key	Item key within the namespace.
value	JSON value to store.

Implements neograph::graph::Store.

search()

std::vector< StoreItem > neograph::graph::InMemoryStore::search ( const Namespace &  ns_prefix, int  limit = 100  ) const

overridevirtual

Search items under a namespace prefix.

Parameters

ns_prefix	Namespace prefix to match (e.g., {"users"} matches all user items).
limit	Maximum number of items to return (default: 100).

Returns

Vector of matching StoreItem objects.

Implements neograph::graph::Store.

size()

size_t neograph::graph::InMemoryStore::size

(

)

const

Get the total number of stored items.

Returns

Total item count.
