  • Method Details

    • tableName

      public final String tableName()

      The name or Amazon Resource Name (ARN) of the table containing the vector index.

      Returns:
      The name or Amazon Resource Name (ARN) of the table containing the vector index.

    • indexName

      public final String indexName()

      The name of the vector index to search. The index must be in the ACTIVE state.

      Returns:
      The name of the vector index to search. The index must be in the ACTIVE state.

    • returnConsumedCapacity

      public final ReturnConsumedCapacity returnConsumedCapacity()
      Returns the value of the ReturnConsumedCapacity property for this object.

      If the service returns an enum value that is not available in the current SDK version, returnConsumedCapacity will return ReturnConsumedCapacity.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from returnConsumedCapacityAsString().

      Returns:
      The value of the ReturnConsumedCapacity property for this object.

    • returnConsumedCapacityAsString

      public final String returnConsumedCapacityAsString()
      Returns the value of the ReturnConsumedCapacity property for this object.

      If the service returns an enum value that is not available in the current SDK version, returnConsumedCapacity will return ReturnConsumedCapacity.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from returnConsumedCapacityAsString().

      Returns:
      The value of the ReturnConsumedCapacity property for this object.

    • hasExpressionAttributeNames

      public final boolean hasExpressionAttributeNames()
      For responses, this returns true if the service returned a value for the ExpressionAttributeNames property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

    • expressionAttributeNames

      public final Map<String,String> expressionAttributeNames()

      One or more substitution tokens for attribute names in an expression. Use the # character in an expression to dereference an attribute name.

      Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasExpressionAttributeNames() method.

      Returns:
      One or more substitution tokens for attribute names in an expression. Use the # character in an expression to dereference an attribute name.

    • hasExpressionAttributeValues

      public final boolean hasExpressionAttributeValues()
      For responses, this returns true if the service returned a value for the ExpressionAttributeValues property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

    • expressionAttributeValues

      public final Map<String,AttributeValue> expressionAttributeValues()

      One or more values that can be substituted in an expression. Use the : character in an expression to dereference an attribute value.

      Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasExpressionAttributeValues() method.

      Returns:
      One or more values that can be substituted in an expression. Use the : character in an expression to dereference an attribute value.

    • projectionExpression

      public final String projectionExpression()

      A string that identifies one or more attributes to retrieve from the index. Separate attribute names with commas. If not specified, the operation returns all attributes projected into the vector index.

      Only attributes projected into the vector index can be retrieved.

      Returns:
      A string that identifies one or more attributes to retrieve from the index. Separate attribute names with commas. If not specified, the operation returns all attributes projected into the vector index.

      Only attributes projected into the vector index can be retrieved.

    • hasSearchVector

      public final boolean hasSearchVector()
      For responses, this returns true if the service returned a value for the SearchVector property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

    • searchVector

      public final List<AttributeValue> searchVector()

      The search vector to compare against the indexed vectors. Each element is a 32-bit IEEE-754 floating point number, provided in DynamoDB list format.

      The number of dimensions must match the number of dimensions configured for the vector index.

      Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasSearchVector() method.

      Returns:
      The search vector to compare against the indexed vectors. Each element is a 32-bit IEEE-754 floating point number, provided in DynamoDB list format.

      The number of dimensions must match the number of dimensions configured for the vector index.

    • searchConditionExpression

      public final String searchConditionExpression()

      A condition expression used to filter the vector search results. The expression can reference attributes defined in the vector index search schema, including HASH and INLINE_FILTER key elements.

      Only the equality operator (=) is supported for HASH attributes. Comparison and range operators are supported for INLINE_FILTER attributes. Only top-level attributes from the search schema can be referenced.

      Returns:
      A condition expression used to filter the vector search results. The expression can reference attributes defined in the vector index search schema, including HASH and INLINE_FILTER key elements.

      Only the equality operator (=) is supported for HASH attributes. Comparison and range operators are supported for INLINE_FILTER attributes. Only top-level attributes from the search schema can be referenced.

    • topK

      public final Integer topK()

      The number of most similar results to return.

      Returns:
      The number of most similar results to return.
