GccAna_Lin2dTanObl Class Reference

This class implements the algorithms used to
create 2d line tangent to a circle or a point and
making an angle with a line.
The angle is in radians.
The origin of the solution is the tangency point
with the first argument.
Its direction is making an angle Angle with the
second argument.

Standard_EXPORT GccAna_Lin2dTanObl (const gp_Pnt2d &ThePoint, const gp_Lin2d &TheLine, const Standard_Real TheAngle)
 This class implements the algorithms used to
create 2d line passing through a point and
making an angle with a line.
.
Standard_EXPORT GccAna_Lin2dTanObl (const GccEnt_QualifiedCirc &Qualified1, const gp_Lin2d &TheLine, const Standard_Real TheAngle)
 This class implements the algorithms used to
create 2d line tangent to a circle and
making an angle with a line.
Exceptions
GccEnt_BadQualifier if a qualifier is inconsistent with
the argument it qualifies (for example, enclosed for a circle).
.
Standard_EXPORT Standard_Boolean IsDone () const
 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.
.
Standard_EXPORT Standard_Integer NbSolutions () const
 Returns the number of of lines, representing solutions computed by this algorithm.
Raises NotDone if the construction algorithm didn't succeed.
.
Standard_EXPORT gp_Lin2d ThisSolution (const Standard_Integer Index) const
 Returns the solution number Index.
Be careful: the Index is only a way to get all the
solutions, but is not associated to theses 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.
.
Standard_EXPORT 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:
- that specified at the start of construction when the
solutions are defined as enclosing or outside with
respect to the argument, or
- that computed during construction (i.e. enclosing or
outside) when the solutions are defined as unqualified
with respect to the argument, or
- GccEnt_noqualifier if the tangency argument is a point.
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.
.
Standard_EXPORT 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 ParSol on
the solution curv.
ParArg is the intrinsic parameter of the point ParArg on
the argument curv. Raises NotDone if the construction algorithm
didn't succeed.
It raises OutOfRange if Index is greater than the number of solutions.
.
Standard_EXPORT void Intersection2 (const Standard_Integer Index, Standard_Real &ParSol, Standard_Real &ParArg, gp_Pnt2d &PntSol) const
 Returns informations about the intersection between the
result number Index and the third argument.
Raises NotDone if the construction algorithm didn't succeed.
It raises OutOfRange if Index is greater than the number of solutions.
.
