	Returns flag to fill in triangulation using double or single precision; FALSE by default.

void	SetDoublePrecision (bool theIsDouble)
	Sets flag to fill in triangulation using double or single precision.

bool	ToSkipDegenerates () const
	Returns TRUE if degenerated triangles should be skipped during mesh loading (only indexes will be checked).

	Starts and reset internal object that accumulates nodes/triangles statistic during data reading.

void	StopStatistic ()
	Stops and nullify internal object that accumulates nodes/triangles statistic during data reading.

void	PrintStatistic () const
	Prints loading statistic. This method should be used between StartStatistic() and StopStatistic() calls for correct results.

bool	Load (const occ::handle< RWMesh_TriangulationSource > &theSourceMesh, const occ::handle< Poly_Triangulation > &theDestMesh, const occ::handle< OSD_FileSystem > &theFileSystem) const
	Loads primitive array.

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
virtual bool	load (const occ::handle< RWMesh_TriangulationSource > &theSourceMesh, const occ::handle< Poly_Triangulation > &theDestMesh, const occ::handle< OSD_FileSystem > &theFileSystem) const =0

virtual bool	finalizeLoading (const occ::handle< RWMesh_TriangulationSource > &theSourceMesh, const occ::handle< Poly_Triangulation > &theDestMesh) const
	Performs additional actions to finalize data loading.
