void	Perform (const IMeshData::IFaceHandle &theDFace, const IMeshTools_Parameters &theParameters, const Message_ProgressRange &theRange=Message_ProgressRange()) override
	Performs processing of the given face.

	~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.

virtual void	buildBaseTriangulation ()=0
	Builds base triangulation using custom triangulation algorithm.

virtual std::pair< int, int >	getCellsCount (const int)
	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.

Protected Member Functions inherited from BRepMesh_BaseMeshAlgo
const IMeshData::IFaceHandle &	getDFace () const
	Gets discrete face.

const IMeshTools_Parameters &	getParameters () const
	Gets meshing parameters.

	Gets common allocator.

const occ::handle< BRepMesh_DataStructureOfDelaun > &	getStructure () const
	Gets mesh structure.

const occ::handle< VectorOfPnt > &	getNodesMap () const
	Gets 3d nodes map.

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.

virtual int	addNodeToStructure (const gp_Pnt2d &thePoint, const int theLocation3d, const BRepMesh_DegreeOfFreedom theMovability, const bool isForceAdd)
	Adds the given 2d point to mesh data structure. Returns index of node in the structure.

virtual gp_Pnt2d	getNodePoint2d (const BRepMesh_Vertex &theVertex) const
	Returns 2d point associated to the given vertex.

virtual bool	initDataStructure ()
	Performs initialization of data structure using existing model data.
