Detailed Description

This template class is define just to be in phase with the LinBox archetype. Most of all methods are inherited from GFqDom<long> class of Givaro. these class allow to construct only extension field with a prime characteristic.

Member Function Documentation

integer cardinality (    )  const [inline]

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

int32 characteristic (    )  const [inline]

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.

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

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.

Element& init (  Element &    x, const double    y = 0.0 )  const [inline]

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.
