Public Member Functions
	CFixedBuffer (const int Capacity)
	Constructor allocates memory so that the specified number of elements of type T can be stored in this buffer object.
void	alloc (const int Capacity)
	Allocates memory so that the specified number of elements of type T can be stored in this buffer object.
void	free ()
	Deallocates a previously allocated buffer.
	operator T* () const
	Returns pointer to the first element of the allocated buffer, nullptr, if not allocated.
void	realloc (const int PrevCapacity, const int NewCapacity)
	Reallocates memory so that the specified number of elements of type T can be stored in this buffer object. Previously allocated data is copied to the new memory buffer.

Detailed Description

template<typename T>
class r8b::CFixedBuffer< T >

Templated memory buffer class for element buffers of fixed capacity.

Fixed memory buffer object. Supports allocation of a fixed amount of memory. Does not store buffer's capacity - the user should know the actual capacity of the buffer. Does not feature "internal" storage, memory is always allocated via the R8B_MEMALLOCCLASS class's functions. Thus the object of this class can be moved in memory.

This class manages memory space only - it does not perform element class construction nor destruction operations.

This class applies 64-byte memory address alignment to the allocated data block.

Template Parameters

T	The type of the stored elements (e.g., double).

Constructor & Destructor Documentation

CFixedBuffer()

template<typename T>

r8b::CFixedBuffer< T >::CFixedBuffer

(

const int

Capacity

)

Constructor allocates memory so that the specified number of elements of type T can be stored in this buffer object.

Parameters

Capacity

Storage for this number of elements to allocate.

Member Function Documentation

alloc()

template<typename T>

void r8b::CFixedBuffer< T >::alloc

(

const int

Capacity

)

Allocates memory so that the specified number of elements of type T can be stored in this buffer object.

Parameters

Capacity

Storage for this number of elements to allocate.

realloc()

template<typename T>

void r8b::CFixedBuffer< T >::realloc	(	const int	PrevCapacity,
		const int	NewCapacity )

Reallocates memory so that the specified number of elements of type T can be stored in this buffer object. Previously allocated data is copied to the new memory buffer.

Parameters

PrevCapacity	Previous capacity of this buffer.
NewCapacity	Storage for this number of elements to allocate.
