Kinetic::RootStack Concept Reference

Definition

 The root of a function.
 

Creation

 RootStack ()

 RootStack (Function f, Root lb, Root ub, Traits tr)
 Construct a Kinetic::RootStack over the roots of f in the half open interval [lb to ub).

bool empty ()
 Return true if there are known to be no more roots left. More...
 

Member Function Documentation

bool Kinetic::RootStack::empty ( )

Return true if there are known to be no more roots left.

There might not actually be any roots of the polynomial left in the interval, but the work necessary to prove this has been delayed.

void Kinetic::RootStack::pop ( )

Advance to the next root.

As a precondition, empty() must be false.

Root Kinetic::RootStack::top ( )

Return the current root.

As a precondition, empty() must be false. Note that the Root returned might not actually be in the interval (since the solver has not yet proved that there are no more roots).
