Detailed Description

This class encapsulates a set of UnivariatePolynomials and its helping methods.

It is important to now that the class is based on the functionality of std::unordered_set but it ensures that only UnivariatePolynomials of the same main variable are inserted.

Member Function Documentation

pair< UnivariatePolynomialSet::iterator, bool > GiNaCRA::UnivariatePolynomialSet::insert ( const UnivariatePolynomial & x ) throw ( invalid_argument )

Inserts an element x into the set.

Throws an exception if the main variable does not fit to the main variables already in the set.

Parameters:

x	the element to insert

Returns:: an iterator to the element and true if it has been inserted and false it has been there before.

template<class InputIterator >

void GiNaCRA::UnivariatePolynomialSet::insert	(	InputIterator	first,
		InputIterator	last
	)		throw ( invalid_argument )

Insert the elements between the iterators into the set.

Throws an exception if only of the inserted polynomials has a different main variable then the main variable of the polynomials already in the set.

Parameters:

first	iterator marking the beginning of the elements to insert
last	iterator marking the end of the elements to insert

Definition at line 68 of file UnivariatePolynomialSet.cpp.

const bool GiNaCRA::UnivariatePolynomialSet::isConstant ( symbol & x ) const

Checks whether the whole set is constant in x.

Parameters:

x	the variable to check for

Returns:: true if the set is constant otherwise false.

Definition at line 41 of file UnivariatePolynomialSet.cpp.

const UnivariatePolynomialSet GiNaCRA::UnivariatePolynomialSet::makePrimitive ( )

Replaces all polynomials by its primitive part.

Returns:: this set where all polynomials are replaced by their primitive part
