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

)

Function 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.

free()

template<typename T >

void r8b::CFixedBuffer< T >::free

(

)

Function deallocates a previously allocated buffer.

operator T*()

template<typename T >

r8b::CFixedBuffer< T >::operator T*

(

)

const

Returns

Pointer to the first element of the allocated buffer, NULL if not allocated.

realloc()

template<typename T >

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

Function 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.
