Very basic paged memory arena class. More...

Public Member Functions
void	reserve (MemoryArenaEntry &entry, std::size_t newSize)
MemoryArenaEntry	allocate (std::size_t size)
void	deallocate (MemoryArenaEntry &entry)
void	set (const MemoryArenaEntry &entry, unsigned short bytePosition, unsigned char value)
char	get (const MemoryArenaEntry &entry, unsigned short bytePosition)
std::size_t	pagesFree () const

Static Public Attributes
static constexpr std::size_t	Size = MaxSize
	The Maximum size to use for data (doesn't include page table)
static constexpr std::size_t	PageSize = AllocationSize
	The allocation size for each page. Note total mem usage is Size + (Size / PageSize) Thus for MemoryArena<2048,10>() you use 2048 + (2048 / 10) = 2253 bytes.

Detailed Description

template<std::size_t MaxSize, std::size_t AllocationSize>
class herald::datatype::MemoryArena< MaxSize, AllocationSize >

Very basic paged memory arena class.

Can be used one arena per dynamic allocation class, or used by multiple classes. In this non-global implementation, pass it as a static reference variable to the class once during application startup after allocation in a main class or similar.
