Detailed Description

This class implements a pool memory resource.

The pool allocates chunks of memory and splits them into blocks managed by a free list. Allocations return pointers from the free list, and deallocations return pointers to the free list.

Member Function Documentation

allocate()

void * sleipnir::PoolResource::allocate ( size_t  bytes, size_t  alignment = alignof(std::max_align_t)  )

inline

Returns a block of memory from the pool.

Parameters

bytes	Number of bytes in the block.
alignment	Alignment of the block (unused).

blocks_in_use()

size_t sleipnir::PoolResource::blocks_in_use ( ) const

inlinenoexcept

Returns the number of blocks from this pool resource that are in use.

deallocate()

void sleipnir::PoolResource::deallocate ( void *  p, size_t  bytes, size_t  alignment = alignof(std::max_align_t)  )

inline

Gives a block of memory back to the pool.

Parameters

p	A pointer to the block of memory.
bytes	Number of bytes in the block (unused).
alignment	Alignment of the block (unused).

is_equal()

bool sleipnir::PoolResource::is_equal ( const PoolResource &  other ) const

inlinenoexcept

Returns true if this pool resource has the same backing storage as another.

operator=() [1/2]

PoolResource & sleipnir::PoolResource::operator= ( const PoolResource &  )

delete

operator=() [2/2]

PoolResource & sleipnir::PoolResource::operator= ( PoolResource &&  )

default
