void IntPatch_ALine::AddVertex ( const IntPatch_Point Pnt)

To add a vertex in the list.

void IntPatch_ALine::ComputeVertexParameters ( const Standard_Real  Tol)

Set the parameters of all the vertex on the line. if a vertex is already in the line, its parameter is modified else a new point in the line is inserted.

Standard_Boolean IntPatch_ALine::D1 ( const Standard_Real  U,
gp_Pnt P,
gp_Vec Du

Returns Standard_True when the derivative at parameter U is defined on the analytic intersection line. In that case, Du is the derivative. Returns Standard_False when it is not possible to evaluate the derivative. In both cases, P is the point at parameter U on the intersection.

Standard_Boolean IntPatch_ALine::FindParameter ( const gp_Pnt P,
