Default constructor

	Destructor.
	BRepMesh_IncrementalMesh (const TopoDS_Shape &theShape, const double theLinDeflection, const bool isRelative=false, const double theAngDeflection=0.5, const bool isInParallel=false)
	Constructor. Automatically calls method Perform.
	BRepMesh_IncrementalMesh (const TopoDS_Shape &theShape, const IMeshTools_Parameters &theParameters, const Message_ProgressRange &theRange=Message_ProgressRange())
	Constructor. Automatically calls method Perform.
void	Perform (const Message_ProgressRange &theRange=Message_ProgressRange()) override
	Performs meshing of the shape.
void	Perform (const occ::handle< IMeshTools_Context > &theContext, const Message_ProgressRange &theRange=Message_ProgressRange())
	Performs meshing using custom context;.
Public Member Functions inherited from BRepMesh_DiscretRoot
	~BRepMesh_DiscretRoot () override
	Destructor.
void	SetShape (const TopoDS_Shape &theShape)
	Set the shape to triangulate.
const TopoDS_Shape &	Shape () const
bool	IsDone () const
	Returns true if triangualtion was performed and has success.
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.
