AddFeatures

APP_ERROR AddFeatures(int n, const float16_t *features, const idx_t *indices) override;

Inserts n feature vectors with specified indexes into the feature database and modifies a feature vector if it already exists.

int n: number of feature vectors to be inserted.

const float16_t *features: feature vectors to be inserted. The length is n × dim (vector dimension).

const idx_t *indices: index corresponding to a feature vector to be inserted. The valid length is n.

N/A

APP_ERROR: return status. For details, see Return Code Reference.

• indices: The range of each feature index is [0, capacity).
• n: The value range is [0, capacity].
• features and indices must be non-null pointers and their lengths must meet the requirements. Otherwise, an out-of-bounds read/write error may occur, causing program breakdown.
