Inheritance diagram for OpenGl_ShadowMapArray:

Public Member Functions
	OpenGl_ShadowMapArray ()=default
	Empty constructor.

void	Release (OpenGl_Context *theCtx)
	Releases all OpenGL resources.

bool	IsValid () const
	Return TRUE if defined.

size_t	EstimatedDataSize () const
	Returns estimated GPU memory usage for holding data without considering overheads and allocation alignment rules.

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.

const_iterator	begin () const noexcept

iterator	begin () noexcept

const_iterator	cbegin () const noexcept

iterator	end () noexcept

const_iterator	end () const noexcept

const_iterator	cend () const noexcept

	NCollection_Array1 () noexcept

	NCollection_Array1 (const int theLower, const int theUpper)

	NCollection_Array1 (const_reference theBegin, const int theLower, const int theUpper, const bool theUseBuffer=true)

	NCollection_Array1 (const size_t theSize)
	Zero-based constructor: allocates theSize elements with lower bound 0. Use At()/ChangeAt() or STL iterators for optimal access (no offset subtraction).

	NCollection_Array1 (pointer theBegin, const size_t theSize)
	Zero-based buffer-reuse constructor: wraps an existing C array of theSize elements. The array does NOT own the buffer and will NOT free it on destruction. Use At()/ChangeAt() or STL iterators for optimal access (no offset subtraction).

	NCollection_Array1 (const NCollection_Array1 &theOther)
	Copy constructor.

	NCollection_Array1 (NCollection_Array1 &&theOther) noexcept
	Move constructor.

virtual	~NCollection_Array1 ()

void	Init (const_reference theValue)
	Initialise the items with theValue.

size_t	Size () const noexcept
	Size query.

int	Length () const noexcept
	Length query (legacy int-returning API).

bool	IsEmpty () const noexcept
	Return TRUE if array has zero length.

int	Lower () const noexcept
	Lower bound.

int	Upper () const noexcept
	Upper bound.

NCollection_Array1 &	Assign (const NCollection_Array1 &theOther)
	Replaces this array by a copy of theOther array. Bounds and length are copied from theOther. When this array wraps an external (non-owned) buffer:

NCollection_Array1 &	CopyValues (const NCollection_Array1 &theOther)
	Copies values from theOther array without changing this array bounds. This array should be pre-allocated and have the same length as theOther; otherwise exception Standard_DimensionMismatch is thrown.

NCollection_Array1 &	Move (NCollection_Array1 &&theOther) noexcept
	Move assignment. This array will borrow all the data from theOther. The moved object will keep pointer to the memory buffer and range, but it will not free the buffer on destruction.

NCollection_Array1 &	Move (NCollection_Array1 &theOther) noexcept

NCollection_Array1 &	operator= (const NCollection_Array1 &theOther)
	Assignment operator;.

NCollection_Array1 &	operator= (NCollection_Array1 &&theOther) noexcept
	Move assignment operator;.

const_reference	First () const noexcept

reference	ChangeFirst () noexcept

const_reference	Last () const noexcept

reference	ChangeLast () noexcept

const_reference	Value (const int theIndex) const
	Constant value access.

const_reference	operator() (const int theIndex) const
	operator() - alias to Value

reference	operator() (const int theIndex)
	operator() - alias to ChangeValue

const_reference	operator[] (const int theIndex) const
	operator[] - alias to Value

reference	operator[] (const int theIndex)
	operator[] - alias to ChangeValue

reference	ChangeValue (const int theIndex)
	Variable value access.

const_reference	At (const size_t theIndex) const
	0-based checked access independent of Lower()/Upper().

reference	ChangeAt (const size_t theIndex)
	0-based checked mutable access independent of Lower()/Upper().

void	SetValue (const int theIndex, const value_type &theItem)
	Set value.

void	SetValue (const int theIndex, value_type &&theItem)
	Set value.

reference	EmplaceValue (const int theIndex, Args &&... theArgs)
	Emplace value at the specified index, constructing it in-place.

void	UpdateLowerBound (const int theLower) noexcept
	Changes the lowest bound. Do not move data.

void	UpdateUpperBound (const int theUpper) noexcept
	Changes the upper bound. Do not move data.

void	Resize (const int theLower, const int theUpper, const bool theToCopyData)
	Resizes the array to specified bounds. No re-allocation will be done if length of array does not change, but existing values will not be discarded if theToCopyData set to FALSE.

void	Resize (const size_t theSize, const bool theToCopyData)
	Resizes the array to theSize elements, keeping the lower bound unchanged.

bool	IsDeletable () const noexcept
