Inheritance diagram for Graphic3d_BoundBuffer:

Public Member Functions
	Graphic3d_BoundBuffer (const occ::handle< NCollection_BaseAllocator > &theAlloc)
	Empty constructor.
bool	Init (const int theNbBounds, const bool theHasColors)
	Allocates new empty array.
void	DumpJson (Standard_OStream &theOStream, int theDepth=-1) const override
	Dumps the content of me into the stream.
Public Member Functions inherited from NCollection_Buffer
	NCollection_Buffer (const occ::handle< NCollection_BaseAllocator > &theAlloc, const size_t theSize=0, uint8_t *theData=nullptr)
	Default constructor. When theData is NULL but theSize is not 0 than buffer of specified size will be allocated.
	~NCollection_Buffer () override
	Destructor.
const uint8_t *	Data () const noexcept
uint8_t *	ChangeData () noexcept
bool	IsEmpty () const noexcept
size_t	Size () const noexcept
	Return buffer length in bytes.
const occ::handle< NCollection_BaseAllocator > &	Allocator () const noexcept
void	SetAllocator (const occ::handle< NCollection_BaseAllocator > &theAlloc)
	Assign new buffer allocator with de-allocation of buffer.
bool	Allocate (const size_t theSize)
	Allocate the buffer.
void	Free ()
	De-allocate buffer.
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.

Data Fields
NCollection_Vec4< float > *	Colors
	pointer to facet color values
int *	Bounds
	pointer to bounds array
int	NbBounds
	number of bounds
int	NbMaxBounds
	number of allocated bounds

Additional Inherited Members
typedef void	base_type
	Returns a type descriptor about this object.
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.
Protected Attributes inherited from NCollection_Buffer
uint8_t *	myData
	data pointer
size_t	mySize
	buffer length in bytes
occ::handle< NCollection_BaseAllocator >	myAllocator
	buffer allocator
