Public Member Functions | |
| GccAna_Lin2dTanPar (const gp_Pnt2d &ThePoint, const gp_Lin2d &Lin1) | |
| This method implements the algorithms used to create a 2d line passing through a point and parallel to another line. More... | |
| GccAna_Lin2dTanPar (const GccEnt_QualifiedCirc &Qualified1, const gp_Lin2d &Lin1) | |
| This method implements the algorithms used to create a 2d line tangent to a circle and parallel to another line. It raises BadQualifier in case of EnclosedCirc. Exceptions GccEnt_BadQualifier if a qualifier is inconsistent with the argument it qualifies (for example, enclosed for a circle). More... | |
| Standard_Boolean | IsDone () const |
| Returns True if the algorithm succeeded. More... | |
| Standard_Integer | NbSolutions () const |
| Returns the number of solutions. Raises NotDone if the construction algorithm didn't succeed. More... | |
| gp_Lin2d | 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. More... | |
| void | 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. More... | |
| void | 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. More... | |
