Member Function Documentation

◆ IsDone()

Standard_Boolean GccAna_Lin2dTanPar::IsDone ( ) const

Returns True if the algorithm succeeded.

◆ NbSolutions()

Standard_Integer GccAna_Lin2dTanPar::NbSolutions ( ) const

Returns the number of solutions. Raises NotDone if the construction algorithm didn't succeed.

◆ Tangency1()

void GccAna_Lin2dTanPar::Tangency1 ( const Standard_Integer  Index,
Standard_Real ParSol,
Standard_Real ParArg,
gp_Pnt2d Pnt 
) const

Returns informations about the tangency point between the result number Index and the first argument. ParSol is the intrinsic parameter of the point on the solution curv. ParArg is the intrinsic parameter of the point on the argument curv. ParArg is equal 0 when the solution is passing thrue a point. Raises NotDone if the construction algorithm didn't succeed. It raises OutOfRange if Index is greater than the number of solutions.

◆ ThisSolution()

gp_Lin2d GccAna_Lin2dTanPar::ThisSolution ( const Standard_Integer  Index) const

Returns the solution number Index and raises OutOfRange exception if Index is greater than the number of solutions. Be careful: the Index is only a way to get all the solutions, but is not associated to those outside the context of the algorithm-object. raises NotDone if the construction algorithm didn't succeed. It raises OutOfRange if Index is greater than the number of solutions.

◆ WhichQualifier()

void GccAna_Lin2dTanPar::WhichQualifier ( const Standard_Integer  Index,
GccEnt_Position Qualif1 
) const

Returns the informations about the qualifiers of the tangency arguments concerning the solution number Index. It returns the real qualifiers (the qualifiers given to the constructor method in case of enclosed, enclosing and outside and the qualifiers computed in case of unqualified). Raises NotDone if the construction algorithm didn't succeed. It raises OutOfRange if Index is greater than the number of solutions.
