API Definition

int Add(int nb, const float *xb, int consecutive, int level);

int Add(int nb, const float *xb, int consecutive, int reorder, int level);

Function

Builds a graph index.

Parameters

Parameter	Data Type	Description	Value Range
nb	int	Data volume of the vector base library.	≥ 1. It is recommended that the value be less than 1 billion.
xb	const float *	Data of the vector base library.	The value cannot be null. The length is nb × dim (data volume × feature dimension).
consecutive	int	Block size.	[1, 31]
level	int	Quantization level.	[0, 3] 0: FP32 quantization. 1: SQ8U quantization. 2: SQ4U quantization. 3: FP16 quantization.
reorder	int	Indicates whether to enable base library vector reordering.	0 or 1.

Return Value

Data Type	Description
int	If the parameter value is not within the value range, −1 is returned. If this API is called after calling Load/Deserialize/LoadGraph, −1 is returned. Otherwise, 0 is returned.
