Constructor.

void First()

Goto first point on circle.

bool IsElm() const

At valid position ?

operator bool() const

At a valid position ?

const Index2dC & Data() const

Get point.
Largest error from radius should be less than 0.5

const Index2dC & operator *() const

Get current point.

bool Next()

Goto next point.
Returns true if we're now at a valid point.

bool operator ++(int)

Goto next point.
Returns true if we're now at a valid point.

void Dummy()
