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.

Constructor & Destructor Documentation

PoolResource() [1/3]

slp::PoolResource::PoolResource ( size_t  blocks_per_chunk )

PoolResource() [3/3]

slp::PoolResource::PoolResource ( PoolResource &&  )

default

Move constructor.

Member Function Documentation

allocate()

void * slp::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).

Returns

A block of memory from the pool.

blocks_in_use()

size_t slp::PoolResource::blocks_in_use ( ) const

inlinenoexcept

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

Returns

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

deallocate()

void slp::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 slp::PoolResource::is_equal ( const PoolResource &  other ) const

inlinenoexcept

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

Parameters

other

The other pool resource.

Returns

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

operator=() [1/2]

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

delete

Copy assignment operator.

Returns

This pool resource.

operator=() [2/2]

PoolResource & slp::PoolResource::operator= ( PoolResource &&  )

default

Move assignment operator.

Returns

This pool resource.
