Public Member Functions | |
Construction | |
Constant_Polynomial_Iterator (const Constant_Polynomial *, bool at_end=false) | |
Creates an iterator for poly and starts at the leading term. | |
Destruction | |
~Constant_Polynomial_Iterator () | |
Iteration | |
virtual void | restart_iteration () |
This should move the iterator to the leading term. | |
virtual void | moveRight () |
Moves right in the polynomial, to the next smaller monomial. | |
virtual void | moveLeft () |
Moves left in the polynomial, to the next larger monomial. | |
virtual bool | canMoveRight () const |
Can this iterator move right, or would it fall off? | |
virtual bool | canMoveLeft () const |
Can this iterator move left, or would it fall off? | |
virtual bool | fellOff () const |
Reports true iff the iterator no longer points to a valid monomial. More... | |
Data access | |
virtual const Monomial & | currMonomial () const |
Reports the monomial at the current position. | |
virtual const Prime_Field_Element & | currCoeff () const |
Reports the coefficient at the current position. | |
![]() | |
virtual | ~Polynomial_Iterator ()=0 |
needed to avoid undefined behavior when disposing | |
const Polynomial_Iterator & | operator++ () |
Moves right in the polynomial, to the next smaller monomial. | |
virtual const Abstract_Polynomial * | my_poly () const |
Reports the polynomial on which this is iterating. | |
const Polynomial_Term | operator* () const |
C++11 iteration. | |

Reports true iff the iterator no longer points to a valid monomial.
This is NOT the same as pointing to a monomial with coefficient zero; this is true when the iterator would probably report inaccurate data.
Implements Polynomial_Iterator.
