void  Results (const Geom2dGcc_Circ2dTanOnRadGeo &Circ) 
Standard_Boolean  IsDone () const 
Returns true if the construction algorithm does not fail (even if it finds no solution). Note: IsDone protects against a failure arising from a more internal intersection algorithm which has reached its numeric limits. More...  
Standard_Integer  NbSolutions () const 
Returns the number of circles, representing solutions computed by this algorithm. Exceptions: StdFail_NotDone if the construction fails. More...  
gp_Circ2d  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 carefull: the Index is only a way to get all the solutions, but is not associated to theses outside the context of the algorithmobject. Exceptions Standard_OutOfRange if Index is less than zero or greater than the number of solutions computed by this algorithm. StdFail_NotDone if the construction fails. More...  
void  WhichQualifier (const Standard_Integer Index, GccEnt_Position &Qualif1) const 
Returns the qualifier Qualif1 of the tangency argument for the solution of index Index computed by this algorithm. The returned qualifier is: More...  
void  Tangency1 (const Standard_Integer Index, Standard_Real &ParSol, Standard_Real &ParArg, gp_Pnt2d &PntSol) 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. PntSol is the tangency point on the solution curv. PntArg is the tangency point on the argument curv. Exceptions Standard_OutOfRange if Index is less than zero or greater than the number of solutions computed by this algorithm. StdFail_NotDone if the construction fails. More...  
void  CenterOn3 (const Standard_Integer Index, Standard_Real &ParArg, gp_Pnt2d &PntSol) const 
Returns the center PntSol on the second argument (i.e. line or circle) of the solution of index Index computed by this algorithm. ParArg is the intrinsic parameter of the point on the argument curv. PntSol is the center point of the solution curv. PntArg is the projection of PntSol on the argument curv. Exceptions: Standard_OutOfRange if Index is less than zero or greater than the number of solutions computed by this algorithm. StdFail_NotDone if the construction fails. More...  
Standard_Boolean  IsTheSame1 (const Standard_Integer Index) const 
Returns true if the solution of index Index and the first argument of this algorithm are the same (i.e. there are 2 identical circles). If Rarg is the radius of the first argument, Rsol is the radius of the solution and dist is the distance between the two centers, we consider the two circles to be identical if Rarg  Rsol and dist are less than or equal to the tolerance criterion given at the time of construction of this algorithm. OutOfRange is raised if Index is greater than the number of solutions. notDone is raised if the construction algorithm did not succeed. More...
