Constructor & Destructor Documentation

GivaroMontg (  const integer &  p  )  [inline]

Constructor from an integer this constructor use the ZpzDom<TAG> constructor

Member Function Documentation

integer& characteristic (  integer &  c  )  const [inline]

Characteristic. Return integer representing characteristic of the domain. Returns a positive integer to all domains with finite characteristic, and returns 0 to signify a domain of infinite characteristic. Returns: integer representing characteristic of the domain.

integer& cardinality (  integer &  c  )  const [inline]

Cardinality. Return integer representing cardinality of the domain. Returns a non-negative integer for all domains with finite cardinality, and returns -1 to signify a domain of infinite cardinality. Returns: integer representing cardinality of the domain

Element& init (  Element &  x, const integer &  y = 0 )  const [inline]

Initialization of field base Element from an integer. Behaves like C++ allocator construct. This function assumes the output field base Element x has already been constructed, but that it is not already initialized. We assume that the type of Element is short int. this methos is just a simple cast. Returns: reference to field base Element. Parameters: x  field base Element to contain output (reference returned). y  integer.

integer& convert (  integer &  x, const Element &  y )  const [inline]

Conversion of field base element to an integer. This function assumes the output field base element x has already been constructed, but that it is not already initialized. Returns: reference to an integer. Parameters: x  integer to contain output (reference returned). y  constant field base element.
