public class CoherenceEmbeddingStore extends Object implements dev.langchain4j.store.embedding.EmbeddingStore<dev.langchain4j.data.segment.TextSegment>
An EmbeddingStore backed by an Oracle Coherence NamedMap.

  • Field Details

    • DEFAULT_MAP_NAME

      public static final String DEFAULT_MAP_NAME
      The default NamedMap name.

    • documentChunks

      protected final com.tangosol.net.NamedMap<com.oracle.coherence.ai.DocumentChunk.Id,com.oracle.coherence.ai.DocumentChunk> documentChunks
      The NamedMap used to store the document chunks.

    • normalizeEmbeddings

      protected final boolean normalizeEmbeddings

  • Constructor Details

    • CoherenceEmbeddingStore

      protected CoherenceEmbeddingStore(com.tangosol.net.NamedMap<com.oracle.coherence.ai.DocumentChunk.Id,com.oracle.coherence.ai.DocumentChunk> namedMap, boolean normalizeEmbeddings)
      Create an CoherenceEmbeddingStore.

      This method is protected, instances of CoherenceEmbeddingStore are created using the builder.

      Parameters:
      namedMap - the NamedMap to contain the document chunks
      normalizeEmbeddings - true if this CoherenceEmbeddingStore should call Embedding.normalize() on embeddings when adding or searching
