//! Most of the time, a domain is defined by two extremities.

//! An extremity is made of :
|
|
//! - a point in 2d-space (Pnt2d from gp),
|
|
//! - a parameter on the curve,
|
|
//! - a tolerance in the 2d-space.
|
|
//! Sometimes, it can be made of 0 or 1 point ( for an infinite
|
|
//! or semi-infinite line for example).
|
|
//!
|
|
//! For Intersection algorithms, Ellipses and Circles
|
|
//! Domains must be closed.
|
|
//! So, SetEquivalentParameters(.,.) method must be called

|
//! after initializing the first and the last bounds.
