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_tData () const noexcept
 
uint8_tChangeData () 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_Transientoperator= (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_TransientThis () 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
 
intBounds
 pointer to bounds array
 
int NbBounds
 number of bounds
 
int NbMaxBounds
 number of allocated bounds
 

Additional Inherited Members

- Public Types inherited from Standard_Transient
typedef void base_type
 Returns a type descriptor about this object.
 
- Static Public Member Functions inherited from Standard_Transient
static constexpr const charget_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_tmyData
 data pointer
 
size_t mySize
 buffer length in bytes
 
occ::handle< NCollection_BaseAllocatormyAllocator
 buffer allocator
