Methods

checkDimensions(List<VectorRecord> records) → void

Available on VectorStore, provided by the VectorStoreOperations extension

Validates records against this store's dimensions.
checkNamespace(String? namespace) → void

Available on VectorStore, provided by the VectorStoreOperations extension

Validates namespace against this store's capabilities.
clear({String? namespace}) → Future<void>
Removes everything in namespace, or everywhere when it is null.
inherited
