Constructors

ProjectiveECCPoint({required CurveFp curve, required BigInt x, required BigInt y, required BigInt z, BigInt? order, bool generator = false}): Constructs a ProjectiveECCPoint from the given coordinates and optional order and generator flag. The curve parameter specifies the elliptic curve. x, y, and z are the projective coordinates of the point. order is the order of the point, and generator indicates if the point is a generator.
factory
ProjectiveECCPoint.fromAffine(BaseProjectivePointNative point, {bool generator = false}): Constructs a ProjectiveECCPoint from an BaseProjectivePointNative in affine coordinates.
factory
ProjectiveECCPoint.fromBytes({required CurveFp curve, required List<int> data, BigInt? order}): Constructs a ProjectiveECCPoint from a byte representation. The curve parameter specifies the elliptic curve, and data is the byte data. order is the order of the point.
factory
ProjectiveECCPoint.infinity(CurveFp curve): Constructs a special ProjectiveECCPoint representing infinity on the elliptic curve. The curve parameter specifies the elliptic curve.
