| bool | IsExtendAtStart () const override |
| bool | IsExtendAtEnd () const override |
| void | SetTrim (const occ::handle< Geom2d_Curve > &Cu) |
| Trim <me> by a domain defined by the curve <Cu>. This domain is the set of the points which are nearest from <Cu> than the extremitis of <Cu>. | |
| void | SetTrim (const double uf, const double ul) |
| Trim <me> by a domain defined by uf and ul. | |
| void | Reverse () override |
| Changes the direction of parametrization of <me>. The "FirstParameter" and the "LastParameter" are not changed but the orientation of the curve is modified. If the curve is bounded the StartPoint of the initial curve becomes the EndPoint of the reversed curve and the EndPoint of the initial curve becomes the StartPoint of the reversed curve. | |
| double | ReversedParameter (const double U) const override |
| Computes the parameter on the reversed curve for the point of parameter U on this curve. Note: The point of parameter U on this curve is identical to the point of parameter ReversedParameter(U) on the reversed curve. | |

| Returns the order of continuity of the curve. Raised if N < 0. | |
| occ::handle< Geom2d_Geometry > | Copy () const override |
| void | Transform (const gp_Trsf2d &T) override |
| Transformation of a geometric object. This transformation can be a translation, a rotation, a symmetry, a scaling or a complex transformation obtained by combination of the previous elementaries transformations. (see class Transformation of the package Geom2d). The following transformations have the same properties as the previous ones but they don't modified the object itself. A copy of the object is returned. | |
| double | FirstParameter () const override |
| Returns the value of the first parameter. Warnings : It can be RealFirst or RealLast from package Standard if the curve is infinite. | |
| double | LastParameter () const override |
| Value of the last parameter. Warnings : It can be RealFirst or RealLast from package Standard if the curve is infinite. | |
| bool | IsClosed () const override |
| Returns true if the curve is closed. Examples : Some curves such as circle are always closed, others such as line are never closed (by definition). Some Curves such as OffsetCurve can be closed or not. These curves are considered as closed if the distance between the first point and the last point of the curve is lower or equal to the Resolution from package gp which is a fixed criterion independent of the application. | |
| bool | IsPeriodic () const override |
| Returns true if the parameter of the curve is periodic. It is possible only if the curve is closed and if the following relation is satisfied : for each parametric value U the distance between the point P(u) and the point P (u + T) is lower or equal to Resolution from package gp, T is the period and must be a constant. There are three possibilities : . the curve is never periodic by definition (SegmentLine) . the curve is always periodic by definition (Circle) . the curve can be defined as periodic (BSpline). In this case a function SetPeriodic allows you to give the shape of the curve. The general rule for this case is : if a curve can be periodic or not the default periodicity set is non periodic and you have to turn (explicitly) the curve into a periodic curve if you want the curve to be periodic. | |

| Standard_Transient * | This () const |
| Returns non-const pointer to this object (like const_cast). For protection against creating handle to objects allocated in stack or call from constructor, it will raise exception Standard_ProgramError if reference counter is zero. | |
| int | GetRefCount () const noexcept |

| void | IncrementRefCounter () noexcept |
| Increments the reference counter of this object. Uses relaxed memory ordering since incrementing only requires atomicity, not synchronization with other memory operations. | |

| Decrements the reference counter of this object; returns the decremented value. Uses release ordering for the decrement to ensure all writes to the object are visible before the count reaches zero. An acquire fence is added only when the count reaches zero, ensuring proper synchronization before deletion. This is more efficient than using acq_rel for every decrement. | |
