Enum VectorEncoding

    • Enum Constant Detail

      • BYTE

        public static final VectorEncoding BYTE
        Encodes vector using 8 bits of precision per sample. Values provided with higher precision (eg: queries provided as float) *must* be in the range [-128, 127]. NOTE: this can enable significant storage savings and faster searches, at the cost of some possible loss of precision.
      • FLOAT32

        public static final VectorEncoding FLOAT32
        Encodes vector using 32 bits of precision per sample in IEEE floating point format.
    • Field Detail

      • byteSize

        public final int byteSize
        The number of bytes required to encode a scalar in this format. A vector will nominally require dimension * byteSize bytes of storage.
    • Method Detail

      • values

        public static VectorEncoding[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
        for (VectorEncoding c : VectorEncoding.values())
        an array containing the constants of this enum type, in the order they are declared
      • valueOf

        public static VectorEncoding valueOf​(String name)
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
        name - the name of the enum constant to be returned.
        the enum constant with the specified name
        IllegalArgumentException - if this enum type has no constant with the specified name
        NullPointerException - if the argument is null
