     BRepMesh_BaseMeshAlgo ()
     Constructor.
     ~BRepMesh_BaseMeshAlgo () override
     Destructor.
    void Perform (const IMeshData::IFaceHandle &theDFace, const IMeshTools_Parameters &theParameters, const Message_ProgressRange &theRange=Message_ProgressRange()) override
     Performs processing of the given face.
    Public Member Functions inherited from IMeshTools_MeshAlgo
     ~IMeshTools_MeshAlgo () override=default
     Destructor.
    Public Member Functions inherited from Standard_Transient
     Standard_Transient ()
     Empty constructor.
     Standard_Transient (const Standard_Transient &)
     Copy constructor – does nothing.
    Standard_Transient & operator= (const Standard_Transient &)
     Assignment operator, needed to avoid copying reference counter.
    virtual ~Standard_Transient ()=default
     Destructor must be virtual.
    virtual const opencascade::handle< Standard_Type > & DynamicType () const
     Returns a type descriptor about this object.
    bool IsInstance (const opencascade::handle< Standard_Type > &theType) const
     Returns a true value if this is an instance of Type.
    bool IsInstance (const char *const theTypeName) const
     Returns a true value if this is an instance of TypeName.
    bool IsKind (const opencascade::handle< Standard_Type > &theType) const
     Returns true if this is an instance of Type or an instance of any class that inherits from Type. Note that multiple inheritance is not supported by OCCT RTTI mechanism.
    bool IsKind (const char *const theTypeName) const
     Returns true if this is an instance of TypeName or an instance of any class that inherits from TypeName. Note that multiple inheritance is not supported by OCCT RTTI mechanism.
    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
     Get the reference counter of this object.
    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.
    int DecrementRefCounter () noexcept
     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.
    virtual void Delete () const
     Memory deallocator for transient classes.

    Protected Member Functions

    void generateMesh (const Message_ProgressRange &theRange) override
     Generates mesh for the contour stored in data structure.

     Returns size of cell to be used by acceleration circles grid structure.
    virtual void postProcessMesh (BRepMesh_Delaun &, const Message_ProgressRange &)
     Performs processing of generated mesh. By default does nothing. Expected to be called from method generateMesh() in successor classes.

    virtual int registerNode (const gp_Pnt &thePoint, const gp_Pnt2d &thePoint2d, const BRepMesh_DegreeOfFreedom theMovability, const bool isForceAdd)
     Registers the given point in vertex map and adds 2d point to mesh data structure. Returns index of node in the structure.
