Additional Inherited Members
Public Types inherited from Standard_Transient
typedef void	base_type
	Returns a type descriptor about this object.
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.

Member Function Documentation

ComputeAbsoluteDeflection()

static double BRepMesh_Deflection::ComputeAbsoluteDeflection ( const TopoDS_Shape & theShape, const double theRelativeDeflection, const double theMaxShapeSize )

static

Returns absolute deflection for theShape with respect to the relative deflection and theMaxShapeSize.

Parameters

theShape	shape for that the deflection should be computed.
theRelativeDeflection	relative deflection.
theMaxShapeSize	maximum size of the whole shape.

Returns

absolute deflection for the shape.

ComputeDeflection() [1/3]

static void BRepMesh_Deflection::ComputeDeflection ( const IMeshData::IEdgeHandle & theDEdge, const double theMaxShapeSize, const IMeshTools_Parameters & theParameters )

static

Computes and updates deflection of the given discrete edge.

ComputeDeflection() [2/3]

static void BRepMesh_Deflection::ComputeDeflection ( const IMeshData::IFaceHandle & theDFace, const IMeshTools_Parameters & theParameters )

static

Computes and updates deflection of the given discrete face.

ComputeDeflection() [3/3]

static void BRepMesh_Deflection::ComputeDeflection ( const IMeshData::IWireHandle & theDWire, const IMeshTools_Parameters & theParameters )

static

Computes and updates deflection of the given discrete wire.

IsConsistent()

static bool BRepMesh_Deflection::IsConsistent ( const double theCurrent, const double theRequired, const bool theAllowDecrease, const double theRatio = 0.1 )

static

Checks if the deflection of current polygonal representation is consistent with the required deflection.

Parameters

[in]	theCurrent	Current deflection.
[in]	theRequired	Required deflection.
[in]	theAllowDecrease	Flag controlling the check. If decrease is allowed, to be consistent the current and required deflections should be approximately the same. If not allowed, the current deflection should be less than required.
[in]	theRatio	The ratio for comparison of the deflections (value from 0 to 1).
