Inheritance diagram for TopoDS_TCompound:

Public Member Functions
	TopoDS_TCompound ()
	Creates an empty TCompound.
occ::handle< TopoDS_TShape >	EmptyCopy () const override
	Returns an empty TCompound.
Public Member Functions inherited from TopoDS_TShape
bool	Free () const
	Returns the free flag.
void	Free (bool theIsFree)
	Sets the free flag.
bool	Locked () const
	Returns the locked flag.
void	Locked (bool theIsLocked)
	Sets the locked flag.
bool	Modified () const
	Returns the modification flag.
void	Modified (bool theIsModified)
	Sets the modification flag.
bool	Checked () const
	Returns the checked flag.
void	Checked (bool theIsChecked)
	Sets the checked flag.
bool	Orientable () const
	Returns the orientability flag.
void	Orientable (bool theIsOrientable)
	Sets the orientability flag.
bool	Closed () const
	Returns the closedness flag.
void	Closed (bool theIsClosed)
	Sets the closedness flag.
bool	Infinite () const
	Returns the infinity flag.
void	Infinite (bool theIsInfinite)
	Sets the infinity flag.
bool	Convex () const
	Returns the convexness flag.
void	Convex (bool theIsConvex)
	Sets the convexness flag.
TopAbs_ShapeEnum	ShapeType () const
	Returns the type as a term of the ShapeEnum enum: VERTEX, EDGE, WIRE, FACE, SHELL, SOLID, COMPSOLID, COMPOUND. The type is embedded in the lower 4 bits of the state.
int	NbChildren () const
	Returns the number of direct sub-shapes (children).
virtual void	DumpJson (Standard_OStream &theOStream, int theDepth=-1) const
	Dumps the content of me into the stream.
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.

	Set a bit flag.
