      • withVectors

        @Deprecated
public SearchIteratorParam.Builder withVectors​(List<?> vectors)
        Deprecated.
        Sets the target vectors. Note: Deprecated in v2.4.0, for the reason that the sdk cannot know a ByteBuffer is a BinarVector or Float16Vector/BFloat16Vector. Replaced by withFloatVectors/withBinaryVectors/withFloat16Vectors/withBFloat16Vectors/withSparseFloatVectors. It still works for FloatVector/BinarVector/SparseVector, don't use it for Float16Vector/BFloat16Vector.
        Parameters:
        vectors - list of target vectors: if vector type is FloatVector, vectors is List of List Float; if vector type is BinaryVector, vectors is List of ByteBuffer; if vector type is SparseFloatVector, values is List of SortedMap[Long, Float];
        Returns:
        Builder
