A simple pool allocator built on top of a bump allocator.

The pool contains objects of type T, or objects of some type derived from type T.

Function documentation

template<typename T, size_t Size, size_t Align> template<typename TSubClass, typename... Args>
TSubClass* slang::PoolAllocator<T, Size, Align>::emplace(Args && ... args)

Allocates and constructs a new object of type TSubClass, reusing pooled memory if any is available and requesting more from the underlying BumpAllocator if not.

template<typename T, size_t Size, size_t Align> template<typename... Args>
T* slang::PoolAllocator<T, Size, Align>::emplace(Args && ... args)

Allocates and constructs a new object of type T, reusing pooled memory if any is available and requesting more from the underlying BumpAllocator if not.

template<typename T, size_t Size, size_t Align> template<typename TSubClass>
void slang::PoolAllocator<T, Size, Align>::destroy(TSubClass* elem)

Destroys the given object and returns its memory to the pool to be reused by future allocations.
