Method Details

getRemoteCache

public org.infinispan.client.hotrod.RemoteCache<String, LangChainInfinispanItem> getRemoteCache()

Gets the underlying Infinispan remote cache

Returns:

RemoteCache

add

public String add(Embedding embedding)

Description copied from interface: EmbeddingStore

Adds a given embedding to the store.

Specified by:

add in interface EmbeddingStore<TextSegment>

Parameters:

embedding - The embedding to be added to the store.

Returns:

The auto-generated ID associated with the added embedding.

add

public void add(String id,
 Embedding embedding)

Description copied from interface: EmbeddingStore

Adds a given embedding to the store.

Specified by:

add in interface EmbeddingStore<TextSegment>

Parameters:

id - The unique identifier for the embedding to be added.

embedding - The embedding to be added to the store.

add

public String add(Embedding embedding,
 TextSegment textSegment)

Description copied from interface: EmbeddingStore

Adds a given embedding and the corresponding content that has been embedded to the store.

Specified by:

add in interface EmbeddingStore<TextSegment>

Parameters:

embedding - The embedding to be added to the store.

textSegment - Original content that was embedded.

Returns:

The auto-generated ID associated with the added embedding.

addAll

public List<String> addAll(List<Embedding> embeddings)

Description copied from interface: EmbeddingStore

Adds multiple embeddings to the store.

Specified by:

addAll in interface EmbeddingStore<TextSegment>

Parameters:

embeddings - A list of embeddings to be added to the store.

Returns:

removeAll

public void removeAll()

Description copied from interface: EmbeddingStore

Removes all embeddings from the store.

Specified by:

removeAll in interface EmbeddingStore<TextSegment>

removeAll

public void removeAll(Filter filter)

Description copied from interface: EmbeddingStore

Removes all embeddings that match the specified Filter from the store.

Specified by:

removeAll in interface EmbeddingStore<TextSegment>

Parameters:

filter - The filter to be applied to the Metadata of the TextSegment during removal. Only embeddings whose TextSegment's Metadata match the Filter will be removed.
