void  Results (const GccAna_Circ2d2TanRad &Circ) 
void  Results (const Geom2dGcc_Circ2d2TanRadGeo &Circ) 
Standard_Boolean  IsDone () const 
This method returns True if the algorithm succeeded. Note: IsDone protects against a failure arising from a more internal intersection algorithm, which has reached its numeric limits. More...  
Standard_Integer  NbSolutions () const 
This method returns the number of solutions. NotDone is raised if the algorithm failed. 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. Warning This indexing simply provides a means of consulting the solutions. The index values are not associated with these solutions outside the context of the algorithm object. 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, GccEnt_Position &Qualif2) const 
Returns the qualifiers Qualif1 and Qualif2 of the tangency arguments for the solution of index Index computed by this algorithm. The returned qualifiers are: 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 PntSol on the solution curv. ParArg is the intrinsic parameter of the point PntSol on the argument curv. OutOfRange is raised if Index is greater than the number of solutions. notDone is raised if the construction algorithm did not succeed. More...  
void  Tangency2 (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 second argument. ParSol is the intrinsic parameter of the point PntSol on the solution curv. ParArg is the intrinsic parameter of the point PntSol on the argument curv. OutOfRange is raised if Index is greater than the number of solutions. notDone is raised if the construction algorithm did not succeed. More...  
Standard_Boolean  IsTheSame1 (const Standard_Integer Index) const 
Returns true if the solution of index Index and, respectively, the first or second argument of this algorithm are the same (i.e. there are 2 identical circles). If Rarg is the radius of the first or second 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...  
Standard_Boolean  IsTheSame2 (const Standard_Integer Index) const 
Returns true if the solution of index Index and, respectively, the first or second argument of this algorithm are the same (i.e. there are 2 identical circles). If Rarg is the radius of the first or second 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.
