Public Member Functions
	IVtkOCC_Shape (const TopoDS_Shape &theShape, const occ::handle< Prs3d_Drawer > &theDrawerLink=occ::handle< Prs3d_Drawer >())
	Constructor for OCC IShape implementation.

	~IVtkOCC_Shape () override
	Destructor.

IVtk_IdType	GetSubShapeId (const IVtk_IShape::Handle &) const
	Returns unique ID of the given sub-shape within the top-level shape.

const TopoDS_Shape &	GetShape () const
	Get the wrapped original OCCT shape.

IVtk_IdType	GetSubShapeId (const TopoDS_Shape &theSubShape) const
	Get local ID of a sub-shape.

NCollection_List< IVtk_IdType >	GetSubIds (const IVtk_IdType) const override
	Get ids of sub-shapes composing a sub-shape with the given id.

const TopoDS_Shape &	GetSubShape (const IVtk_IdType theId) const
	Get a sub-shape by its local ID.

void	SetSelectableObject (const occ::handle< SelectMgr_SelectableObject > &theSelObj)
	Stores a handle to selectable object used by OCCT selection algorithm in a data field. This object internally caches selection data so it should be stored until the shape is no longer selectable. Note that the selectable object keeps a pointer to OccShape.

const occ::handle< SelectMgr_SelectableObject > &	GetSelectableObject () const

const occ::handle< Prs3d_Drawer > &	Attributes () const
	Return presentation attributes.

void	SetAttributes (const occ::handle< Prs3d_Drawer > &theDrawer)

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.

Additional Inherited Members
Static Public Member Functions inherited from Standard_Transient
static constexpr const char *	get_type_name ()
	Returns a type descriptor about this object.

static const opencascade::handle< Standard_Type > &	get_type_descriptor ()
	Returns type descriptor of Standard_Transient class.

IVtkOCC_Shape::IVtkOCC_Shape	(	const TopoDS_Shape &	theShape,
		const occ::handle< Prs3d_Drawer > &	theDrawerLink = occ::handle< Prs3d_Drawer >() )

Constructor for OCC IShape implementation.

Parameters

[in]	theShape	shape to display
[in]	theDrawerLink	default attributes to link

◆ ~IVtkOCC_Shape()

IVtkOCC_Shape::~IVtkOCC_Shape ( )

override

Destructor.

Member Function Documentation

◆ Attributes()

const occ::handle< Prs3d_Drawer > & IVtkOCC_Shape::Attributes ( ) const

inline

Return presentation attributes.

◆ GetSelectableObject()

const occ::handle< SelectMgr_SelectableObject > & IVtkOCC_Shape::GetSelectableObject ( ) const

inline

Returns: Handle to the selectable object for this shape.

◆ GetShape()

const TopoDS_Shape & IVtkOCC_Shape::GetShape ( ) const

inline

Get the wrapped original OCCT shape.

Returns: TopoDS_Shape the wrapped original OCCT shape

◆ GetSubIds()

NCollection_List< IVtk_IdType > IVtkOCC_Shape::GetSubIds ( const IVtk_IdType ) const

overridevirtual

Get ids of sub-shapes composing a sub-shape with the given id.

Implements IVtk_IShape.

◆ GetSubShape()

const TopoDS_Shape & IVtkOCC_Shape::GetSubShape ( const IVtk_IdType theId ) const

Get a sub-shape by its local ID.

Parameters

[in] id local ID of a sub-shape

Returns: TopoDS_Shape& a sub-shape

◆ GetSubShapeId() [1/2]

IVtk_IdType IVtkOCC_Shape::GetSubShapeId ( const IVtk_IShape::Handle & ) const

Returns unique ID of the given sub-shape within the top-level shape.

◆ GetSubShapeId() [2/2]

IVtk_IdType IVtkOCC_Shape::GetSubShapeId ( const TopoDS_Shape & theSubShape ) const

Get local ID of a sub-shape.

Returns unique ID of the given sub-shape within the top-level shape. Note that the sub-shape ID remains unchanged until the top-level is modified by some operation.

Parameters

[in] subShape sub-shape whose ID is returned

Returns: local ID of the sub-shape.

◆ SetAttributes()

void IVtkOCC_Shape::SetAttributes ( const occ::handle< Prs3d_Drawer > & theDrawer )

◆ SetSelectableObject()

void IVtkOCC_Shape::SetSelectableObject ( const occ::handle< SelectMgr_SelectableObject > & theSelObj )

inline

Stores a handle to selectable object used by OCCT selection algorithm in a data field. This object internally caches selection data so it should be stored until the shape is no longer selectable. Note that the selectable object keeps a pointer to OccShape.

Parameters

[in] selObj Handle to the selectable object
